Episode 2:   

 • Richard Dawkins - Sex, Death and the ...  

Why does an atheist bother to get up in the morning?

That's the question Richard Dawkins seeks to answer as he continues his exploration of the big questions of life in a world shaking off religious faith.

In a journey that takes him from the casinos of Las Vegas to Buddhist monasteries in the foothills of the Himalayas, Richard Dawkins examines how both religious and non-religious people struggle to find meaning in their lives.

He looks at how our existence is ruled by chance, meeting people whose fate was to be born into extreme poverty in India's slums and the survivors of a natural disaster in Joplin, Missouri, a city ripped apart in 2011 by a tornado on a random course.

In the face of what appears to be a blindly indifferent universe, Dawkins argues that we each have to forge our own sense of meaning.

He meets the comedian Ricky Gervais, an atheist since the age of seven, for whom meaning comes through doing something creative.

For Dawkins, it is the awe and wonder in scientific enquiry - from the human genome to the quest for the Higgs Boson - that get him up in the morning.

0:04
We are all going to die. We just don't know how, or when.
0:11
Easily snuffed out in an instant, what is life's meaning?
0:16
Oh, man! I see it, I see it. We're gonna get closer, we're gonna get closer.
0:22
Over 1,000 tornadoes rip through the United States every year. Most do little damage. This one was different.
0:31
There it is. Oh, my gosh! It's going to go down that road right there.
0:37
Oh, gosh, that is a monster tornado!
0:49
Right up there on the back wall, that was the sanctuary, that's where the altar was. Behind that was the house that I was in, just real close to it.
1:02
The tornado destroyed the city of Joplin, Missouri and killed 162 people.
1:11
That was Green Briar Nursing Home, and there were five people died in there. It's a terrible, terrible sight. It's an awful sight.
1:19
In the face of catastrophe, this Catholic priest finds comfort in his religious faith.
1:26
I have to believe there's a plan and that God is going to accomplish something through this.
1:32
I feel like God is doing something for us. I think we have to see somewhere a higher power.
1:39
Father Monaghan's faith must have been tested to the limit by this terrible experience.
1:46
For those of us who don't believe in any kind of Gods, how do we cope?
1:58
More and more people now realise there is no God.
2:03
Yet religious values have dominated our lives for hundreds of years and still have a hold over us.
2:11
In this series I'm exploring what reason and science can offer us in the place of religion
2:17
to bring comfort in the face of death, help us tell right from wrong,
2:24
or provide meaning in an indifferent and uncaring universe.
2:31
So do you think that we in the west are too materialistic? So do you think that we in the west are too materialistic? I think so. I suppose Jesus is an unpaid babysitter.
2:39
It's like, if I'm not watching you, Jesus is. Do you think mothers are ever going to meet their babies again? Do you think mothers are ever going to meet their babies again? Yes.
2:46
The mothers believe it, and the fathers.
2:54
If there is no God, what is the meaning of life?
3:00
Some of the greatest minds in history have battled depression and even toyed with suicide, struggling to answer
3:07
the ultimate question that we all face - what's the point?
3:13
For many, there is no point if there is no God. One of the questions I'm most often asked after giving a lecture
3:21
is, "Why do you bother to get up in the mornings?" This film is my attempt to answer that question.
3:50
Like most English children, I was sent to Christian schools and I was confirmed into the Church of England at the age of 13.
3:57
I believed in the Christian God. A couple of years later, I realised it wasn't true.
4:03
There was no God. There was nothing out there. Many people have had that experience
4:09
and different people respond to it in very different ways.
4:18
One of the oddest reactions to facing up to life without God was that of the great Russian novelist Leo Tolstoy.
4:29
Like me, Tolstoy was brought up a Christian and, as a young man, lost his faith.
4:34
He had wealth, a family, and celebrity status thanks to his novels War And Peace and Anna Karenina.
4:42
But in his late 40s, he began to question everything.
4:48
Tolstoy was in despair, staring into an abyss of suicidal depression.
4:53
He could find no answer to what tormented him.
4:58
Why do I live? Is there any meaning in my life that will not be annihilated
5:05
by the inevitability of death? Desperate to believe that life had a greater purpose,
5:11
Tolstoy scoured philosophy and the sciences for what it might be, but his torment only deepened.
5:19
You are a temporary incidental accumulation of particles. You are a randomly-united lump of something.
5:35
Eventually, Tolstoy found an answer and stepped back from the abyss.
5:51
Mount St Bernard Abbey in Leicestershire is home to 36 Cistercian monks.
5:57
And this, in essence, was Tolstoy's solution - spiritual retreat and devotion.
6:06
There are no special announcements this morning.
6:11
Our order is what's called a contemplative order so we stay within the confines of the monastery.
6:17
We don't have schools, hospitals or parishes. We stay within the monastery.
6:23
And you're silent for part of the day, is that right? We are, for a good part of the day, especially in the early morning. We are, for a good part of the day, especially in the early morning. Yes.
6:30
So the library is just up here. Yes.
6:36
Oh, my, this is very nice. It is a very nice library indeed, yes. 'Like Tolstoy, these monks live between two worlds.
6:44
'Their library is better than I would have expected.' Stephen Hawking's Universe, Just Six Numbers, Carl Sagan.
6:52
Excellent, very good. I wish I'd brought some of my books to present to you!
6:58
Oh, there's one, there! We have one. Oh, there's one, there! We have one. Oh, really? Richard Dawkins, Modern Science Writing. Oh, excellent! The Oxford Book of Modern Science Writing. Very good.
7:06
There may be others, erm... Well, I won't do that usual thing authors do of looking for them!
7:17
Tolstoy's answer to the threat of meaninglessness was to go back and consciously embrace God.
7:26
He does exist. I had only to recognise this for an instant and I would feel the possibility and joy of living.
7:36
I returned to a belief in God. I now knew that I could not live without it.
7:45
As an old man, Tolstoy separated himself from society to lead a Christian sect.
7:51
He ended up, like these monks, a religious recluse.
7:56
But I want to know, can a person find meaning and fulfilment, devoting himself to spiritual life?
8:04
Brother Michael, one of the youngest monks in the order, has, like Tolstoy, given up the world and earthly possessions.
8:15
My life I direct towards God and finding a relationship with God, and I find meaning in that,
8:21
and as...hopefully I grow towards God, I'll grow towards other people. What do you miss about the life you could've had?
8:29
Erm... This morning I had to go to the chemist, and on the way out, there was a young lady with her child
8:39
and as they walked down the street, they had Tigger the tiger holding between their hands.
8:44
Tigger from Winnie the Pooh? Tigger from Winnie The Pooh, and it stirred my heart. My heart sort of...
8:49
You feel you'd have liked to have had a child of your own? Yeah. It's just like...yeah. I've given up a family, which is part of the life.
8:58
I worry that these men are running from reality and squandering their lives.
9:04
Isn't facing up to the challenges of the real world what makes life worthwhile?
9:10
Can you talk while polishing? Yes. Brother William gave up a career as a banker
9:16
to join the monastery ten years ago. The meaning of life for me
9:21
is being there for other people. Yes. And it's a sacrifice that I'm willing to make.
9:30
But if you want to do good to other people, it seems a slightly odd way to go about it
9:36
to shut yourself away in a monastery. Couldn't you do more good if you were out there in the outside world?
9:42
You can see how our prayers affect people's lives, and how they've come through a personal problem,
9:51
that they've felt our support here. (THEY CHANT)
9:57
These monks find meaning in devotion to God, in prayer and solitude.
10:10
They're entitled to their beliefs of course. But, what a slender life to lead
10:16
when you could be out there in the real world, teaching, learning, maybe doing good.
10:26
It seemed to me to be a sort of sadly inadequate life. Not really a life at all.
10:34
Just very, very sad.
10:40
Of course, I don't believe in God, but I do understand Tolstoy's predicament.
10:46
I just don't see how cloistering yourself away like this can add meaning to life.
10:56
Perhaps a better approach would be to embrace life's uncertainties and take a few risks?
11:18
Many of our greatest minds have struggled with the idea that if there is no God, life has no meaning.
11:29
One of the bleakest reactions was that of Graham Greene. Greene was of course to become one of the great Catholic writers of the 20th century,
11:37
but as a young man he was agnostic. He was also reckless and extremely bored.
11:43
He carried what he called his "war against boredom" to a shocking and dangerous extreme.
11:50
Greene lived to the ripe old age of 86, but statistically he shouldn't have made it past 19.
11:59
"I remember very clearly the afternoon I found the revolver "in the brown deal corner cupboard
12:04
"in a bedroom which I shared with my elder brother. "It was the early autumn of 1923.
12:11
"I slipped the revolver into my pocket "and the next I remember, was crossing the Berkhamstead Common towards Ashridge Beaches."
12:19
Greene had been reading a book about soldiers during the Russian Civil War.
12:25
Away from the frontline, they invented hazardous games to avoid boredom. "This was not suicide, whatever a coroner's jury might have said,
12:34
"it was a gamble with five chances to one against an inquest.
12:40
"I slipped a bullet into a chamber and holding the revolver behind my back spun the chambers round.
12:51
"I put the muzzle of the revolver into my right ear."
12:58
CHAMBER CLICKS "There was a minute click and looking down I could see the charge had moved into the firing position.
13:07
"I was out by one." Graham Greene lived by chance. He had absolutely no control
13:14
over the outcome when he pulled the trigger. What Greene did was utterly crazy. No matter how bored I was,
13:22
I would never trust my life to chance in such a way. But the reality is that we have less control over our lives than we might like to think.
13:47
When a tornado struck Joplin, Missouri in May 2011,
13:52
death and destruction were indiscriminate. The young Graham Greene would have embraced the truth of that tornado.
14:03
Joplin's fate hung on chance, just like his game of Russian roulette.
14:11
While 7,000 buildings were blown away, others survived unscathed.
14:22
There is tremendous survivor's guilt in the community. That, I haven't experienced before.
14:28
Survivor's guilt meaning why did I survive when someone else died?
14:33
Why did that little child die, I'm 70 years of age, why didn't you take me, God? Why should that mother lose that child?
14:43
But do you think he could have stopped the tornado? Of course he could, he could stop anything he wants. Of course he could, he could stop anything he wants. Then, why didn't he?
14:49
Er...because we don't understand, it's a mystery, he is a mystery. I can't intellectually explain that.
14:56
And if someone tries to do that, they're gonna come to a dead end and say it makes no sense.
15:07
It's almost moving the way religious people struggle, twist and turn to find some excuse for this,
15:13
some sort of meaning, some part of God's plan. If it was part of anybody's plan, what an unthinkably awful plan it would have to be.
15:26
But even if you're an atheist, the idea of living or dying by chance alone is hard to accept.
15:33
Atheists may think they've given up God, but it's only human to cling to the idea that "things happen for a reason".
15:42
If you look at the misfortune and fortune in human life, in the universe generally,
15:50
there is no pattern as relates to people, the pattern is entirely related to physics.
15:56
The universe has exactly the properties we'd expect if there was no plan, no design,
16:02
no aim, just blind indifferent...forces of nature.
16:19
If, like Graham Greene, you understand life as a game of chance, and if you believe there is no God pulling your strings, making plans for you, why not just play the game?
16:28
The great gambling game of life.
16:37
Unbelievable place. It's sort of trying to be the seven wonders of the world.
16:44
Look at that medieval castle there. There's the Statue of Liberty.
16:53
There's a replica of Venice somewhere. There's the Chrysler Building. I'm often told that my vision of a godless future is just as devoid of meaning as Las Vegas.
17:04
That without God, all you're left with is materialism and mindless slot machines.
17:11
But I've come here because I think Las Vegas reveals something fascinating, humanity's deep-seated belief that we can prevail over chance.
17:23
People come here filled with hope. Everybody knows the casinos have a terrific mark-up percentage for the house
17:30
and yet they still go on feeding that hope and feeding the slot machines and losing their money.
17:38
Hey, Richard. How's it going? Hey, Richard. How's it going? OK. You winning? You winning? No, I've lost every time so far.
17:43
Well, now your luck's gonna change, because I know physics! OK. He may look like a card sharp, but the gentleman in the shades is actually a physicist.
17:52
Leonard Mlodinow is fascinated by how human beings are incapable of understanding chance.
18:02
32. I won and I lost.
18:07
When people are playing these games we see around us, am I right that many of them, even if there's absolutely no bias between red and black,
18:16
many people will say, "Oh, well it has been red, red, red, red for such a long time, it's black's turn." That's right. That's called The Gambler's Fallacy.
18:25
I you flip a coin a zillion times, you're going to get about half a zillion heads and half a zillion tails.
18:31
So people's thinking goes, if they bothered to logically think about it, is that, "OK, I've seen 10 tails in a row,
18:38
"so if it's gonna be half heads and half tails, the heads better catch up." But that's not the way it works. But that's not the way it works. OK.
18:44
You could throw it a zillion times and get all heads.
18:49
The point about our brain is that it insists on seeing order, meaning and pattern even where thereis none.
18:56
It's a very human characteristic to fool ourselves that we are in control.
19:02
In today's world, it seems that we make more mistakes seeing patterns that aren't there rather than missing patterns that are there.
19:09
In fact, there's a great experiment on that, they put a rat in front of a red light and a green light.
19:14
And the red light and the green light flash without any pattern, at random. But the green light flashes 75% of the time, and the red light flashes 25% of the time.
19:24
And the rat, if it guesses correctly which is going to flash, it gets a little sugar water. So when they let the rats do this,
19:30
they see after a while that the green light is flashing more than the red light and they just start guessing green, green, green, green, green every time.
19:37
And they get it right 75% of the time and are happy with that. That's what you should do. That's what you should do. Yeah.
19:42
But people, we think we know better, right? So when they put humans in front of such an experiment,
19:50
they won't do what the rat does. They've seen that it's 75% green and they'll guess a pattern. They'll go, green, green, red, green, green, green, red.
19:56
They'll start spewing out these red and greens in some weird pattern that's tailored to be 75% green and 25% red,
20:04
thinking that they can beat the system, just like the people here in the casino think they can.
20:09
And when you do that, you end up about, I think, 60% of the time you get it right, instead of 75%. And so the humans are out performed by a rat.
20:15
That's because we see patterns where there aren't any. That's just the way our minds work.
20:21
Too clever by half. Or too clever by three quarters, in this case. Too clever by half. Or too clever by three quarters, in this case. Yes. I'm going to throw everything on my birthday.
20:28
Yours is the 26th? Mine is the 26th! Yours is the 26th? Mine is the 26th! Oh, wow! Both our birthdays are the 26th! So... (LAUGHS)
20:35
26 is even so I'm going to win that too. Maybe I should put this on odd?
20:41
Perhaps this is part of the explanation why religion evolved in the first place,
20:47
it satisfied our desperate desire to find meaning and order in the chaos.
20:52
In playing the ultimate game of chance, Russian roulette,
20:57
the young Graham Greene grasped what so many of us fail to, there is no pattern.
21:03
26! 26! We have no control. Ooh! We came so close!
21:10
Greene took his chances and pulled the trigger on another five occasions before the effect of what he called "his adrenaline drug" wore off.
21:23
What Greene did may seem crazy, but there is a grim logic to it. Seize the reins. Dance with death.
21:29
You're going to die anyway. You're going to die anyway. CHAMBER CLICKS Happily for Greene, he beat the odds.
21:40
Greene would later convert to Roman Catholicism, but Russian roulette of a kind stayed with him.
21:46
As a journalist and spy, Greene risked his life in numerous war zones.
21:54
"The fear of ambush served me just as effectively "as the revolver from the corner cupboard in the life-long war against boredom."
22:06
Tolstoy found meaning by hiding himself away. Greene went in the opposite direction.
22:13
But the next great mind I shall consider tried to argue meaning into even the most meaningless toil imaginable.
22:35
More and more of us now do not believe in God or life after death. We live and then we die, and that's it.
22:44
We are born by chance and our lives are shaped by chance events.
22:53
I know this is a difficult pill to swallow for many people, especially those for whom religion still has a hold over their lives.
23:01
Many people have struggled to come to terms with the reality of a purely physical universe. So, how do we find meaning?
23:19
The Second World War laid bare the extent of man's capacity for evil.
23:28
In Paris, philosophers like Albert Camus met in cafes like this
23:33
to try to make sense of the brutality. "Without the aid of eternal values, it is legitimate
23:41
"and necessary to wonder whether life has a meaning."
23:47
Camus was interested in what he called "the absurd", that our life must have meaning for us to value it,
23:54
but we live in a world that offers no meaning. Unlike Tolstoy and Graham Greene, Camus rejected religion
24:02
as a source of the meaning he craved. He found inspiration in another myth.
24:08
The story of a man whom the Ancient Greek gods had cursed.
24:15
Camus consoled himself with the myth of Sisyphus, in which Sisyphus was condemned to spend his whole time
24:20
rolling a boulder up a mountain and then it rolled to the bottom again, he went to the bottom and rolled it up again,
24:26
and this went on forever. For Camus, accepting even this most futile and repetitive of tasks
24:36
and not giving up, itself had value. "The struggle itself towards the heights
24:42
"is enough to fill a man's heart. "We must imagine Sisyphus happy."
24:50
Camus took comfort from this because by going to the bottom of the mountain again and rolling the stone back up, he was at least doing something.
24:59
But can we really find meaning in futile work?
25:05
Sisyphus may seem admirable to a French intellectual, but I don't see the appeal of resigning oneself
25:12
to life's injustices.
25:25
India - one of the fastest developing and most unequal economies in the world.
25:32
The human condition doesn't come much more human than this, or much more extreme. Everything's going on - the noise, the bustle.
25:41
It's like an ant-heap of activity. It's a terrifying and yet rather a moving sight.
25:53
This latter-day Sisyphus is called Hori Lal. His struggle is to clean the streets
26:00
and the public lavatory here in Varanasi. His task is as endless as Sisyphus' boulder-rolling.
26:07
These streets are never clean. Do you enjoy your job?
26:13
TRANSLATION: Yes, yes. I enjoy doing my job. Do you do the same thing every day?
26:18
TRANSLATION: Yes, I do it every day. How long have you been doing this job? TRANSLATION: It must be 20 years now.
26:27
What hope do you have for the future? TRANSLATION: What hope can I have? I have a job to do and I will continue doing it.
26:36
It's fate. What we have been made, we will remain. It can't be changed.
26:45
I suppose there is something a bit inspiring about Hori Lal's cheerfulness and good humour in the face of life's hardships.
26:53
Perhaps it's what Camus saw in the myth of Sisyphus, and it's certainly a wonderful antidote to us whingers
26:59
in the rich West, when we dare to moan about patchy mobile phone reception, or the cost of supermarket food.
27:11
But what bothers me is why Hori Lal has been cursed like Sisyphus. It's because here, life's lottery begins at birth,
27:19
thanks to the confines of the ancient caste system. This is the Sunday edition of the Hindustan Times
27:27
and it's got a section called "Matrimonials", in which fathers advertise for husbands for their daughters.
27:36
And there's a section called "Brides", where men advertise for wives.
27:43
And the men are usually described as handsome. The women are often described as homely, which I presume means home-loving.
27:50
But a curious thing about this matrimonials page is the way it's classified. There are headings like Brahmin,
27:58
and other names from the ancient Hindu caste system, whereby society is stratified into levels, into separate castes,
28:09
which are not supposed to marry each other.
28:14
Ancient Hindu scripture divided society into four distinct groups that you could be born into -
28:20
scholars... warriors...
28:25
merchants... and labourers. Falling outside this system were the Dalits, the untouchables,
28:34
who, like Hori Lal, were condemned to shovel the excrement of the higher castes.
28:51
This is where I think Camus got it wrong. Rather than accept fate, surely meaning is found
28:58
when we revolt against outrageous fortune?
29:04
Mahendra? Yes. Very nice to meet you. Please come. Thank you.
29:12
TRANSLATION: When my father died, I was told that because there is no money in the family now, you can't study any more.
29:19
At that time I was very sad because I had this dream from the start, I have to study.
29:30
Like Hori Lal, Mahendra is a Dalit. His father died when he was 14 years old, leaving the family penniless.
29:39
Mahendra spent the next four years working as a bonded labourer, weaving saris.
29:44
But, unlike Sisyphus, Mahendra defied the gods and threw his boulder away.
29:51
TRANSLATION: I had to face so much discrimination in the society for being a Dalit that I felt education could be a good medium
29:59
to get out of the system. A lot of people in your position would probably have given up.
30:06
I hugely admire you for not giving up, but what drove you at that time?
30:12
TRANSLATION: I had always felt that I have to become a part of the mainstream society.
30:20
And that is why I have this thing that I have to study a lot and earn money so that I can reach mainstream society.
30:33
Today, Mahendra is studying for a master's degree and wants to fight the Dalit cause -
30:38
help other boulder-rollers break free from their struggle.
30:44
It is wonderful to see how an individual can bring himself out of poverty and downtrodden-ness.
30:54
With Mahendra, we come closer to finding at least one worthwhile meaning of life. He is creating his own meaning,
31:01
but it has a deeper purpose, making a difference to others as well.
31:07
We can find meaning in struggle, but we have to define our own meaning in our own struggle,
31:13
not one dictated by the gods, by authority or by accident of birth.
31:31
So I think meaning is subjective, something personal we may not all agree on.
31:37
But that shouldn't be an invitation to egotism or self-absorption.
31:44
Here in northern India, Westerners still come in droves
31:49
in the hope of finding some deeper meaning in Eastern mysticism.
31:58
People go up mountains for refreshment, they go up mountains for wisdom. Moses went up Mount Sinai and came down
32:05
with the tablets of traditional Hebrew wisdom. There are lots of people who come from all over the world
32:11
to a place like this, up a mountain like this, where there's a Tibetan monastery, seeking what they would call spiritual wisdom.
32:23
Geshe Lhakdor is a Master of Tibetan Buddhism. He's the Dalai Lama's official translator and archivist.
32:33
The complete teaching of the Buddha is aimed towards transforming your mental outlook
32:40
because the ultimate purpose is to remove all kinds of problems and sufferings, and problems and sufferings and disturbances
32:49
cannot be removed by relying on external forces or external material sources, or your relatives and friends.
32:56
At the end of the day, the real source of long-lasting peace and happiness has to come from within.
33:04
For a Buddhist, what matters is accepting that reality will always change. To be happy in this changing reality, Buddhists teach that
33:13
we must eliminate our attachments to people and possessions. I sort of half understand that.
33:23
They try to get that sense of direction or happiness from material accumulation, from marriage, from wealth, from name,
33:31
but in all these cases here or there, they get a lot of problems, a lot of difficulties.
33:38
So do you think that we in the West are too materialistic in our way of life?
33:43
I think so, to be honest. I think so, I think so. I think I would agree with you that one doesn't want to devote
33:49
one's life to accumulating material, hedonistic happiness. I'm not sure that I would look inward though.
33:56
I think I would I might get happiness from... music and from science....
34:02
Exactly. When you do something that is creative, something that really satisfies your inner arts, you know.
34:08
Yes, but meditating and looking inwards doesn't sound to me as though that's really doing that. Perhaps it helps...
34:15
Of course, of course. The peace and happiness, the tranquillity that you get when you know how to stay alone
34:22
and go within cannot be measured by anything else.
34:28
While I agree that an unhealthy consumerism dominates our lives today, how convincing is it
34:34
that we should detach ourselves from the real world through meditation?
34:45
The great minds we've looked at, Tolstoy, Greene and Camus, all stood out in deeply religious times.
34:52
But we are now at a point in history, in the West at least, when more people than ever are atheist.
34:59
So if we are finally shaking off the influence of God, how nowadays do we find meaning?
35:06
I'm going to talk to an outspoken satirist of modern life. That's that. No. That's that.
35:12
Religion is that "nooooo!"
35:29
We've seen that there isn't a simple, single answer to the meaning of life in a world without God.
35:35
Meaning is something we need to carve out for ourselves.
35:40
We have to find our own meaning from the opportunities and challenges that life throws our way,
35:47
even if that does mean defying convention sometimes. I'm going to meet a man who has definitely defined his own way
35:55
and made a huge success of it, but he has ruffled quite a few feathers in doing so.
36:01
Thanks to everyone in the room for being good sports. Thanks to NBC. Thanks to Hollywood Foreign Press.
36:06
Um, thank you for watching at home. And thank you to God for making me an atheist.
36:12
When I signed off the Golden Globes by saying... and thanked God for making me an atheist,
36:19
now, clearly, that was a play on words. Um, it was a little bit of
36:24
a redressing the balance to everyone who thanks God for winning an award. I've never seen so much outrage
36:31
as thanking God for making me an atheist. Now, correct me if I'm wrong. If God exists, He did make me an atheist, didn't he?
36:38
Didn't He? Why did He do that? I read about that. It was astonishing. It really did cause outrage, did it?
36:44
You usually have to murder and eat someone
36:49
to get that much publicity in America. How funny. How funny. Yeah. How funny. Yeah. How very funny. When did you first realise that you didn't believe in God?
36:57
My next brother, Bob, when I was about eight... He was 11 years older than me so he was about 19.
37:03
And I was drawing a picture of Jesus for Bible studies
37:08
and he, er... He came in and he looked at it and he went, "Why do you believe in God?"
37:16
And my mum went "Bob!" And I knew from body language. Why didn't she even want the question?
37:25
Oh. She was hiding something from me. And I thought about it and it all made sense.
37:31
Then I started reading and, um, I've, er... I've been an atheist for 40 years.
37:39
I love that some people mistake atheists for Satanists. Oh, yes.
37:45
I go, "No, I don't believe in him either." He's just as ludicrous. I don't believe in him.
37:50
Why can't God sort out Satan? Why can't he? He's all-powerful. What's he doing? What's he doing?
37:59
'So, why does a 21st-century British atheist get up in the morning?' I think you have to have worth.
38:06
I think you have to feel in yourself you have worth. Friends, family, a loving relationship...
38:14
Um... Just because we're human and that's how we're built.
38:20
And for me personally, something creative. It doesn't have to be painting the Sistine Chapel.
38:28
It can be gardening, but I think you have to do something and enjoy it and fill you free time and stand back and think, "I did that."
38:37
These are all reasons to stay around for as long as you can.
38:42
I would agree with all that, and I think I would add "understanding" as well.
38:58
Religious believers tell me they're puzzled that non-believers like Ricky Gervais and me
39:03
can find any meaning or purpose in a godless existence.
39:09
But, for me, the world teems with meaning. It is up to each of us to give our own lives meaning
39:17
through our work, our relationships, and passions, and, I think, through one other thing - understanding who we are,
39:23
and trying to understand why we're here.
39:29
That has been the mission of Western science, the most important tool I believe mankind has ever invented.
39:38
For centuries, human eyes could see clearly no further than only a few miles.
39:44
Telescopes enabled our eyes to leap outwards, and see distant stars millions of miles away.
39:51
Even better than that, a telescope is a kind of time machine. Because it takes light so long to reach us from a distant star,
39:59
when you look at a distant star you're looking backwards in time, maybe hundreds of millions of years.
40:06
And if you look at a distant galaxy, you may be looking at the origin of the universe itself.
40:13
You're looking at the very beginning of space and time -
40:18
the Big Bang.
40:31
Humanity's gaze has also turned towards inner space. Microscopes have unlocked our understanding of the cells
40:38
that make up all living things and revealed the world of the smallest and simplest organisms
40:44
around us and in us. The new science of genetics has unexpectedly completely revolutionised
40:52
and unified our understanding of life on Earth. Meanwhile, physics has discovered particles smaller by far
41:00
even than the atom. And at laboratories like CERN, scientists studying the collisions of these particles
41:08
are on the cusp of understanding how the universe got started in the first place.
41:15
The poet John Keats voiced what many people fear about science -
41:22
..that, in explaining the world, it makes it less amazing, less extraordinary, somehow banal.
41:31
"Philosophy will clip an Angel's wings, "Conquer all mysteries by rule and line,
41:39
"Empty the haunted air and gnomed mine - "Unweave a rainbow."
41:48
Keats could not have been more wrong. Isaac Newton's unweaving of the rainbow
41:54
led directly to a massive deepening and widening of our understanding of the universe.
41:59
It led to James Clerk Maxwell's theory of electromagnetism and from there to Einstein's special theory of relativity.
42:08
If you think the rainbow has poetic mystery, you should try relativity.
42:16
Science does the opposite of making things banal. It's about unleashing curiosity and uncovering more mysteries to solve.
42:25
We take so much for granted, we've become anaesthetised by our familiarity with what's around us.
42:32
Science shakes off the anaesthetic and we look again with new and clearer eyes.
42:40
If you found a bramble in your garden, you'd probably think it an annoying weed. But like every other plant and every other animal,
42:47
it is an astonishing piece of natural engineering. A leaf is a chemical factory.
42:54
It's a flat-roofed factory and on the flat roof are solar panels gathering sunlight to drive the machinery of the factory.
43:02
There are wheels, almost literally wheels going round and round, biochemical wheels,
43:08
driven by the energy from the sun and manufacturing food for the plant - sugars.
43:15
And the sugars are then piped in this, what almost looks like a river system,
43:20
into the central stem and into the rest of the plant. That's where all the food for the plant comes from
43:27
and even OUR food comes from that because we eat plants, or we eat animals that eat plants,
43:33
and so the energy that drives our bodies, every one of our trillions of cells comes ultimately from the sun
43:40
and it flows down a river system like this ultimately into us.
43:46
It gets even better - the genetic code that's used by this plant is the same as the one that's used by you.
43:54
Even 50% of the genes are the same. This plant is your cousin.
44:00
Just a weed? 'Some people would say that
44:07
'the scientific view is rather bleak and cold. Do you find it bleak?' There's no God-fearing person of any religion
44:14
who...feels as much awe as me as when I see...
44:20
a mountain or a tree. Or the stars. Or the stars. Or the stars. Or, um...
44:27
anything in science and nature and art. And you and I are privileged to be here to enjoy it,
44:34
even if for a short time. That's a wonderful thought. We cherish this life.
44:42
It's sacred... so enjoy it. This is all we've got and it's brilliant.
44:49
Make the most of it. Make the most of it. It's brilliant! It's amazing!
44:59
We are lucky to be born. We win the lottery just in being here at all.
45:05
Your unique identity is the result of one sperm amongst hundreds of millions fertilising one particular egg in one particular sexual exchange.
45:14
And the same lucky break had to favour your ancestors in every generation back to the very beginning of life.
45:23
And we are luckier still as individuals to have been born NOW. We have so much available to us -
45:29
possible only through the understanding that science has already given us.
45:35
Just look how far we've come in my lifetime - we've got life-saving medicine, super-computers, the internet.
45:43
We can travel further and faster, higher and deeper than ever before. We constantly push at the frontiers of possibility.
45:53
Imagine what's still to come!
45:59
We are made by the laws of physics working through four billion years of evolution.
46:05
We have a brief window of life through which to see the universe and understand how we came to be in it.
46:12
The truth may not always be comforting in the face of suffering, but it has a majesty of its own.
46:20
That's what I tell people when they ask me, "Why do you bother to get up in the mornings?"

Part 3:   

 • Richard Dawkins — Sex, Death and the ...  

Evolutionary biologist Richard Dawkins asks if science can provide answers to the big questions we used to entrust to religion.

It's a journey that takes him from Hindu funeral pyres in India to genetics labs in New York.

Dawkins brings together the latest neuroscience, evolutionary and genetic theory to examine why we crave life after death, why we evolved to age and how the human genome is something like real immortality - traits inherited from our distant ancestors that we pass on to future generations.

He meets a Christian dying of motor neurone disease, reminisces about the Wall Street Crash with a 105-year-old stockbroker, and interviews James Watson, the geneticist who co-discovered the structure of DNA.

Dawkins admits to sentimentality in imagining his own church funeral, but he argues we must embrace the truth, however hard that is.

In a television first, he has his entire genome sequenced to reveal the genetic indicators of how he himself may die.

0:12
The novelist Aldous Huxley once wrote that... ..."Most human beings behave as though death were no more than an unfounded rumor".
0:25
But, what happens when you realize the rumor is true?
0:31
Let's face it. None of us, until it hits us in the face, think we're going to die.
0:36
I can still sort of picture the consultant's room. He said "well, I've got some bad news for you"
0:42
"We think you've got within your disease" As we filmed this, Richard Chell has only months to live.
0:50
His comfort lies in his religious faith. For him, death is not the end.
0:57
Death to me, the actual process of dying, is not something I'm scared of. For me, it's going through a door into another room.
1:04
What do you mean by that? I'm a christian, therefore I do believe in a life after death. I do believe that this life is just part of a process...
1:12
...and there's another part of that process to complete. I know very well your feelings about religion and the rest of it...
1:18
...but I would say having a view that is finite is a bit like having half a meal.
1:25
It will leave you hungry at the end of the day. But, of course, the existence of hunger doesn't mean that there's food.
1:32
No, but it means there's a need. And I would argue that there is a food. If you'd face the situation where, like myself, say...
1:39
...you were certainly said well death is very close. And you're going to die.
1:45
Do you think you would feel any differently? Or, are you clear in your own mind, if that was the situation...
1:51
...I'd know exactly how I'd respond and exactly how I'd feel.
1:59
It is a fair question. I follow reason and I don't believe in God.
2:06
But this series is not about whether God exists or not. It's about a more difficult problem.
2:13
What, if anything, can take God's place? Religion has shaped our understanding of life for thousands of years.
2:24
Ideas of the soul, sin and the afterlife...
2:32
are hard to shake off even for non-religious people like me.
2:38
As more and more of us realize there is no God, ... ...what happens as we leave religion behind?
2:45
I have to believe there's a plan... and that God is going to accomplish something through this.
2:51
I suppose Jesus is an unpaid babysitter It's like if I'm not watching you Jesus is.
2:57
So, do you think that we in the West are too materialistic? I think so.
3:03
In this film, to death. Religion has traditionally been thought to bring comfort at the end of life.
3:12
But, does it really? What can science and reason tell us?
3:21
How does someone like me, who has no religion, face death?
3:50
Varanasi, India, one of the oldest cities in the world.
3:58
It has a macabre speciality. It's main business is the industry of death.
4:13
Every year a million Hindu pilgrims visit Varanasi dragging with them some 40,000 corpses...
4:19
to be cremated on the banks of the Ganges.
4:29
This is the holiest place in whole Hinduism. This is the place where Indians aspire to come to die..
4:37
to escape from the cycle of death and rebirth.
4:42
It is the most amazing scene. It's probably been going on like this for centuries, even millennia.
4:48
It looks that there are ashes down here, in the river swirling around.
5:04
As an atheist for whom death is a full stop... I suppose I shouldn't feel sentimental about the carcases.
5:11
They are X people who've ceased to be.
5:24
Yet, I find something a little bit shocking here... The partially burned corpses,
5:33
the locals casually searching for precious metals in the burned remains
5:41
and the rejected dead.
5:48
Although this is clearly steeped in religion, there's a surprising lack of evident reverence or solemnity.
5:57
The people standing around the funeral pyres are doing a job of work and a pretty matter-of-fact way.
6:06
But there is a kind of logic behind the apparent lack of reverence.
6:12
In this religious tradition, the flesh is no longer important. What matters here is releasing the spirit, or soul.
6:25
This is where religion plays its strongest card, the body may not live forever, but the soul does.
6:35
On the face of it, it's a comforting idea and a challenge for an atheist like me.
6:52
If you want to hear the challenge starkly expressed, you can go to a place like this in Kansas City.
7:06
This Catholic hospice, Alexander's house, ... ...is for babies who die within hours of birth.
7:14
These are clearly fatal disorders. Babies perhaps with anencephaly, Potter syndrome, ...
7:19
...or they have no kiddies, severe genetic heart disease, etc. So they're all going to die, ...
7:25
...and so the normal recommendation by the medical profession would probably be an abortion.
7:33
This may, you know, be hard for some people to see. These are many of our babies for whom we've cared.
7:38
Some who have lived here. But all of them that we've cared for. So this is leading us up to where the families stay.
7:50
Over the last 11 years, ... ...Patty Lewis has helped the families of over 500 babies...
7:56
...who've died within these walls. Do you think that mothers are ever going to meet their babies again?
8:02
Yes, I think the mothers believe that too, ... ...and the fathers and the siblings.
8:13
I do sympathize with the desire to meet again somebody... ...whom you've known and loved, ...
8:18
...but newborn baby... I feel very sorry for these parents, but still...
8:25
Reality may be raw, but we have to face it. The baby was born on Saturday 7, 9:11, ...
8:39
...and she came into the world at 6pm and she lived 30 minutes, ... ...and those 30 minutes seemed so short and so precious.
8:48
We hold her, and loved her, ... ...and got to give her a little bath, and put her in a christening outfit, ...
8:55
...and we baptized her, ... ...and the family was there with us, ...
9:00
...and it was a very precious time. Can you talk us through when you first found out that...
9:07
...there was a problem with the baby? We found out in January that we were expecting and...
9:13
...it would be our third. We were overjoyed and we go in for ultrasound... ...to find out if it was born a girl.
9:20
She did the scan and told us there were no kidneys. That was the first time that we had heard that diagnosis...
9:28
...and she called it a lethal pregnancy. So that's when you, sort of, went into shock? More so, yes.
9:34
Did it occur to you that the total sum... ...of suffering would be much less if you'd...
9:40
...drawn a line under it then and restarted your life? You've got to restart your life now and...
9:46
why did you decide to go on for the remaining months?
9:51
Well, there's hope and... ...God can do great things. So, you were hoping for a miracle?
9:57
Hoping for a miracle, but if it wasn't it was still... ...going to be precious and it's a baby and... ...it's a life and it's not my decision to...
10:04
...terminate that. It's not my choice and... ...I carried it and loved it and...
10:09
...could feel it move every single day. And also the 30 minutes or so that we've...
10:14
...got to spend with her was was worth. I didn't have any of the pain, ... ...but I would say it was worth all of the trial...
10:22
...of getting to where we were. No, we didn't get to spend 30 minutes with her, ... ...we got to be with her for like 12 hours.
10:30
You know she wasn't with us spiritually, ... ...but we got to hold her. And you took photographs?
10:36
Oh, yes. They have a form that we printed off.
10:41
She was beautiful, she was perfect. Looks just like her mom right down to her fingernails. Yes, beautiful.
10:49
Wouldn't have changed her for anything. Do you think you'll ever meet the baby?
10:54
Oh, of course, there's great hope in that. We will meet the baby. It's in heaven with God.
11:08
I feel for Renee and Lee. They sincerely think they're gaining reassurance from their faith.
11:21
So now i need to understand how this... ...relationship between death and religion... ...has evolved to be so strong.
11:44
Religion denies death is real. It sets up instead the forbidding prospect of eternity, ...
11:50
...either in heaven, or worse, in hell. For me what's frightening is not death itself, but eternity, ...
11:58
...whether you're there or not. Yet, people still reach instinctively for religion...
12:03
...and its rituals when it comes to the end. Why?
12:10
It's a very very artificial situation. We see the person lying down.
12:16
Unless you're intimately acquainted with... ...someone, you don't really see them lying down. And they may well be dressed in...
12:22
...their own clothes lying down with their... ...eyes closed in an artificial situation. They're inside a wooden box, no?
12:29
All of these things bring us to realism, ... ...but despite that, people are very very...
12:35
...focused on the fact that the last... ...physical connection that they have that... ...person is lying in that coffin and...
12:42
...that's what they're saying farewell to. So, why do people go on with these strange rituals?
12:53
It's the business of walking away from... ...the funeral and feeling that was well done.
13:00
We liked what they've done for us... ...and we feel that we live someone who... ...we cared about very deeply to rest...
13:06
...in a very dignified and meaningful way. Even if the beautiful oak coffin is then...
13:12
...burned or buried, somehow you feel you've... ...given the person a good send-off. Very much so.
13:25
More and more of us have no faith in God, ... ...but be cling to the rituals.
13:32
Even in secular woodland burial sites, ... ...we find death brings illogical superstition.
13:41
It is fascinating to see people thinking... ...of themselves as part of this place.
13:46
They're anticipating their post-mortem identity, ... ...so that when people talk about, ... ...as they can in this pretty face in any...
13:54
...direction. So someone to look up the hill, ... ...someone to look down the hill, ... ...someone to look towards the Sun.
14:00
They are buried in different spatial directions. Douglas Davis is an anthropologist...
14:06
...fascinated by the fasts and trappings... ...surrounding death. You think part of what's going on is a reluctance to believe that...
14:14
...the dead person is really dead? Yes, one baby, the father used to farm around here.
14:20
And so he's been buried looking at towards the hill.
14:26
And to her this is dreadfully important, ... ...because the relatives too are... thinking about their dead after they've died.
14:33
Yes. I find I'm not immune to these notions.
14:39
There's a place in Cornwall where my mother's family come from and...
14:44
...where we used to spend childhood holidays, ... ...called Dollar cove. I think I'm right in saying that's the place where... ...the little tiny Church, mores are on the...
14:52
...beach, more is built in the sand and I've... ...sometimes fantasized about being burried there. With someone the sea crashing in, ...
14:59
...and the tide coming in and out. What is the earlier that would be there for you...
15:04
...in a location for your body? It's totally illogical. It's pure sentimentality.
15:09
I suppose there's no rational defense for it whatever. I mean, one should say just stick stick me in a dustbin bag and turn me away.
15:17
But you don't want to be in a dustbin bag. No, that's right and it is pure sentiment. I mean, we are sentimental animals, ...
15:22
...as well as social animals.
15:28
So, why do even atheists like me carry around this sentimental baggage?
15:38
When did these illogical thoughts first develop?
15:47
As a child, I don't think I worried about God looking down at me... ...and seeing what I was doing.
15:52
I worried about ancestors. I worried about my great-uncles and great aunts... ...looking down from heaven and seeing everything that I did.
16:01
Childish perhaps, but don't let's be too quick to dismiss it.
16:13
From an early age we start to believe that... ...there's more to us than just our physical bodies.
16:19
As this experiment reveals. Should give him a little tickle.
16:25
He's very sweet, isn't he? This is a fake machine to fool children into thinking live beings can be duplicated.
16:36
It's Icky. And there's Icky.
16:44
As scientists, we seem to be committed to... ...the view that if you could take a person... ...and make an exact copy, ...
16:49
...molecule by molecule, that copy would have exactly... ...the same thoughts and memories.
16:55
Would be the same person. But intuition revels. We seem to want to believe that there's...
17:02
...some essence of ourselves, something that... ...would not go across with all those... molecules, something that a religious...
17:09
...person might want to call a soul.
17:16
This is an attempt to look at an old philosophical problem, ... ...which is imagine if you could copy anything, ...
17:23
...and what we've done in these experiments, rather than... ...getting children to imagine that we... ...reproduce a machine which looks as if it...
17:29
...can duplicate and copy anything. A bit like a photocopier for objects.
17:36
Now there's two! We've shown in previous studies that they believe it can copy toys very easily, ...
17:45
...but the question is: ... Would they really extend that to something like a living thing, like a hamster?
17:50
Should we tell him your name? You want to wishper? And so, what copies over is the body of the hamster, ...
17:57
...the ideas of the hamster, ... ....the memories of the hamster? We believe that the intuition is that the physical...
18:03
...object can be copied and therefore the... ...physical body can be copied, ... ...but we're not so sure that children think that the...
18:08
...mind can be copied, just like adults. They have this sense that maybe the mind is... ...different to the physical body.
18:14
Now, the reason this is really interesting is... ...because if you believe that the mind is... ...separate to the physical body, ...
18:19
...then it means that the body goes, but maybe the... ...mind can stay on and exist. And, of course, this allows for all sorts of notions of...
18:27
...spirits and the soul as being something... ...entirely untethered to the fisical world. Disembodied ghosts after death or
18:34
surviving death in other ways. The soul goes on.
18:39
So, these young children believe bodies... ...can be copied, but not minds. Should we have a look?
18:46
One! Two!
18:51
They're already thinking there's... ...something in charge of each being that... ...is unique.
18:56
Something like a soul. Did this hamster see your picture?
19:01
Yes. Does this hamster know what your picture is? No. Does this hamster know your name?
19:07
[Nodding] Does this hamster know your name? No.
19:14
Evolutionary psychology suggest that we have evolved... ...a sense of separate mind or soul, ...
19:20
...because it's useful to us. Because the experience of being in control your body is so pervasive.
19:27
You just feel that you've you've made a decision. You're gonna have a cup of coffee. These things, you feel like you're driving this very complex machine.
19:34
And if you didn't feel like that, ... ...you wouldn't really be very well adapted. To be a fully functional animal, ...
19:40
...which is what are ancestors were, ... ...hunting and feeding and running and escaping from predators, ...
19:47
...you need to feel it like a soul that's in control of the body.
20:02
This is one reason why it's so hard... ...to shake off the religious way of death.
20:08
We are programmed to believe in something like a soul.
20:15
Now, of course, I don't believe in a soul But I, too, have the feeling that there is...
20:20
...some sort of essence of Richard Dawkins, ... ...that makes me who I am. That gives me my unique personal identity.
20:31
To understand more about this, ... ...I need to look at the role our memories play.
20:37
With the person who's known me longest, my mother.
20:43
So, what do we got here? We've got... your first birthday party.
20:49
I have no memory of this at all. That's presumably me, is it? Yes, that's you, in a little dress that your granny sent out.
20:59
Our memories are hugely important to our sense of who we are.
21:06
That's Kilimanjaro. Oh, yes. You used to like saying words like Kilimanjaro.
21:13
Alright! But our memories drives us into a false sense of certainty.
21:19
They are fallible, riddled with errors. Another early memory was being stung by a scorpion.
21:28
- ...and you suddenly jumped off your chair without your shoes on, ...
21:36
...which you weren't allowed to do, ... ...and set on a Scorpion.
21:42
And Ally, our African boy, rushed in and got your foot, ...
21:51
...squeezed it and sucked it for hours.
21:56
And you were screaming. We had to hold you while he sucked your foot.
22:02
My memory is slightly different. My memory's that I was walking along the floor, ... ...and I saw this creature walking across.
22:10
And I thought it was a lizard. I didn't step on it, ... ...I put my foot in the way of it to let it crawl over my foot.
22:18
You jumped off your chair. I don't remember the pain. Don't you? That's interesting because that was a terrible bit.
22:29
We think back to our first memory, ... ...our first big adventure, ... ...and it's almost as though there was a movie camera in our head recording every detail.
22:38
But that's not the way it is, that's an illusion. What we're remembering is a memory of a memory of a memory...
22:44
...of perhaps the real thing. A man may wear a wristwatch when he's 20, ...
22:50
...and the same watch when he's 50. It's the same watch, but is not the same man inside.
22:55
Every atom in his body has changed, has turned over. I'm not the child I once was.
23:02
The child I once was is dead.
23:10
So, the physical cells that once made me are long gone. And my memories are more tenuous than I would wish.
23:19
The connection between younger Richard Dawkins and older Richard Dawkins... ...isn't as strong as I might like it to be.
23:28
And I think this is why the religious idea of something permanent, the soul, is so plausible.
23:37
Now, I want to explore the reality of why we die.
23:56
Religion still dominates our thinking about death. If we get rid of God, what's left?
24:06
I'm on a voyage to tell you the extraordinary truth that science reveals about death.
24:18
According to evolutionary science, ... ...death is not something to be overcome at all. It's a necessary part of the picture.
24:29
I'm joining the scientists on board, ... ...Banger University's Research Vessel, ... ...on the Irish Sea.
24:38
They're studying the lifespan of a species of clam, ... ...called Arctica islandica.
24:43
They may look rather ordinary, ... ...but they have one attribute that is really quite amazing.
24:50
These clams are among the longest living animals on earth.
24:58
Save that one along. The reason why we're so interested in this, ...
25:04
..is that this is a very long live species. We can pull it from the wild, ... ...and we can assign a year almost, you know, to within one year...
25:11
...and how old it is. Basically, the shell grows incremental steps. Each ring is an anual ring, so the growth is very much like a tree.
25:20
Can you guess from this one how old it is? The size growth curve and this is probably 80 to 150 years old.
25:27
The oldest of them, reach what sort of age? Umm, around the UK it's around 220 years.
25:34
In iceland, in the far north, the paint 50, 54 hundred, maybe 500 years.
25:45
Only recently this research team found a clam that... ...had lived for more than half a millennium.
25:55
It's amazing to think that... ...some of these clams that we're dredging up... ...were born before Darwin, ...
26:00
...even before Elizabeth I. So, why do they live so long?
26:09
Any evolutionary explanation of why aging happens has to do two things.
26:14
It has to be able to explain why you see aging in many species.
26:19
It also has to be able to explain... ...why you see enormously long lifespans, ...
26:24
...or possibly, no aging, in a very few species. And, the clams, I think, may be an example of this, ...
26:32
...because you've seen them and handled them yourself. They have enormously thick shells. I don't think there are very many things down there...
26:39
...that can actually fight through them. And so, they can sit around.
26:45
And they can just carry on producing offspring once they reach a certain size.
26:52
These clams are continuing to pass on their genes to the next generation, ...
26:57
...even a 200 and 300 years old. So, from the evolutionary point of view...
27:04
...it's not just that the individuals are well-protected against being eaten. Because there are well protected against being eaten, ...
27:11
...it's a good gamble to stay alive along a long time, ... ...because you've got a good chance of reproducing later.
27:18
Whereas something like a salmon, ... ...has a very poor chance of reproducing again.
27:23
So, it might as well throw everything it's got into one big gamble now. Yeah, there is no point in spending resources to make a body that will last 400 years, ...
27:35
...if your chance of making it through the night is pretty slim.
27:47
So, evolutionary science tells us a lot about aging and death.
27:54
The clams are able to reproduce when there are hundreds of years old. And so, as long as they are able to reproduce, ...
28:00
...their genes keep them alive. We need to see death from a gene's eye point of view.
28:12
Our bodies are survival machines for our genes. Once our genes have got us to reproductive age...
28:19
...and copy themselves into a new generation, ... ...our bodies have less purpose.
28:24
Time bombs inside us go off. We age, we die.
28:33
So, rather than looking upon aging as a wearing out of the body, ... ...perhaps we should see it as a side effect of how genes work.
28:46
Even extraordinary exceptions throw light on this truth.
28:53
This is Irving Kahn, ... ...a financial trader on New York's Madison Avenue, ...
28:59
who's come to work every day since 1927. Irving is a 105 years old.
29:08
Do you remember the wall street crash? Oh yeah, they came just in about...
29:14
...three or four months before the main peak with summer of 1928-29.
29:22
And that was one reason I didn't like the business.
29:27
Because I came here, went to the exchange on Wall Street... ...and found after we got on the floor...
29:34
...that it was like working in a casino.
29:39
I understand that, not just you, ... ...but many members of your family, ... ...are extremly long live.
29:45
Yes, my brother Peter is 103. I'm a 105.
29:51
I have limited regular weight... ...and limited here side... ...and I hope the right number of models.
30:00
Yes, you've got a lot of models, I think. What about your sister, how old is she? She's a 108.
30:06
Mr. Khan, is it possible to give us an idea what ot what it feels like to be your age?
30:12
It's much better and it's much worse.
30:20
So, why do some people's genes keep their bodies going for so much longer?
30:27
The curious case of Irving Kahn and his family... ...has intrigued scientists, ... ...who are trying to answer this very question.
30:36
When we aske our people, ... ...you know, why do you think you'll live to be so old?
30:42
One of the things they're saying... ..."hey it's in my family, my mother was 102, my grandfather was 108".
30:48
Irving can show that... ...he has four other siblings that live to be 100.
30:57
The study looked at 500 aged Ashkenazi Jews, ... ...like Irving Kahn, ...
31:03
...from the same geographical area, ... ...whose environment and genes can be easily compared.
31:13
For Irving and, especially, for for his sister Helen, ... ...she's been smoking for 95 years.
31:20
Two packs for 95 years, ... ...which shows you that if you smoke for 95 years, you life a long life.
31:27
I you can assure that it's true. And Irving have smoked for about 30 years in his life, ...
31:34
...so the point here is that... ...our centenarians, as a group, did not interact...
31:40
...with the environment the way... ...the doctors tell their patients.
31:46
That you have to watch your weight, ... ...you have to exercise, ... ...you shouldn't smoke... ...and you should drink one cup of alcohol a day...
31:54
...and all the things that we know to tell them, ... ...it doesn't matter for them.
31:59
So, for some, lifestyle and environment don't play as... ...larger role as we've been told.
32:06
But, if Irving's genes hold the secret to long life, ... ...why hasn't evolution given us all genes like his?
32:15
If there are genes... ...that increase longevity out into the hundreds, ... ...why didn't actual selection favor those genes...
32:22
...in our ancestral past? Well, I'll tell you there's something very upsetting... ...in this sense in our group.
32:30
First of all, third of the centenarians... ...in the world don't have children. Ok? So, I don't know, is it to having children?
32:37
Raising them? Rearing them? I don't know what. But the point is that... ...there is some exchange between reproduction and aging.
32:45
But also, in my study, ... ...the centenarians had less kids on a much later age...
32:51
...than my control population. So, if the control population has...
32:56
...three to five kids on average, ... ...our centenarians have 1.7 kids on average.
33:01
So, if you're thinking that way, ... ...we're losing longevity genes, right?
33:08
Because in every generation... ...we populate more with kids of the people who...
33:13
...don't have longevity genes... ...that have longevity genes.
33:20
Our genes appear to trade long life for reproduction.
33:25
Longevity seems to be connected... ...to later reproduction, ... ...or no children at all.
33:33
So, how long we live and why we died are dependent on our genes. And i'm about to look my own genetic code...
33:40
...straight in the face.
33:47
Advances in genetic science mean... ...it is now possible for me... ...to get my entire genome decoded.
33:58
There's something very personal and intimate about it as well. And this is something that is absolutely unique to me.
34:04
There's never ever been, ... ...in the history of the world, nor ever will there be again, ... ...a genome which is the same as mine, ...
34:11
...or the same as yours, ... ...or the same as anybody else's.
34:22
This new science is still in its infancy. I'm going to be one of just a dozen people in the world...
34:28
...and the first person in Britain publicly, ... ...to have their whole genome secuenced.
34:39
What we're doing here is very new for us actually, ... ...and it's actually very exciting for us. We're taking the genome of a healthy person...
34:47
...and we're asking what can we learn about that person. The most important bit of information about you...
34:54
...is your genome sequence. But, on a serious note, of course we may find information in your genome...
34:59
...that has clinical or health implications. Yes, I have thought about that.
35:05
And let's go, let's go and do it.
35:12
Having my blood taken... ...is only the first stage in a complex process.
35:18
The most painless blood test I've ever had. Having my genome decoded is, in effect, ...
35:25
...a way of narrowing down how when i'm going to die. My journey to understand death has become personal.
35:33
You have a few hundred mutations... ...which have been reported... ...as being associated with a disease.
35:52
I maybe one of a handful of individuals... ...in the world to have their genome sequenced.
35:58
But, before I find out my results, ... ...I'm off to meet the man who was first.
36:04
And he isn't just anyone. He's one of the two men who made this new science possible.
36:10
James Watson. Well, it's certainly a very beautiful thing.
36:16
Together with Francis Crick, James Watson... ...discovered that genes are digital codes...
36:21
...written on DNA molecules. Watson and Crick's names will live forever.
36:29
And Watson isn't shy about it. So now, I realize how, you know, except for Hawking, ...
36:37
...in the most famous scientists alife.
36:42
I've turned out to be helped by people... ...looking at my DNA. In what way? It revealed that I have a genetic polymorphism...
36:51
...which metabolizes drugs, ... ... and I have one which acts very slowly, ... ...so if I take a beta blocker...
37:00
...it stays in my system for a week, ... ...instead of going away for a day. And so, they have been given them for, you know, ...
37:08
...to help control my blood pressure. And i went to sleep.
37:14
Watson took a personal risk... ...in making his genome available for study.
37:20
Exposing all its imperfections to public scrutiny... ...for the sake of advancing genetic research.
37:27
You get great pleasure from ideas? No, I get pleasure from understanding.
37:33
So, understanding... everything falls into... ...place when you understand. Yes, so you move from... its understanding...
37:39
...er- ....it gives you happiness. And I think it's one of the unique human features, ...
37:48
...because it's not limited to me, ... ...but, it clearly, you know, when you're able to do something.
38:03
This, for me, is what it says thrilling about science. Understanding things, ... ...such as how the DNA molecule underlies all life on earth.
38:15
It's because Watson... ...discovered the structure of DNA... ...over half a century ago, ... ...that today I'm able to have my own genome analyzed.
38:23
And understand what makes me live... ...and how and when I might die.
38:32
Today is a very special day for me. In 50 years lots of people will be able to say this, ...
38:37
...but today I'm one of very few people... ...who's had their entire genome sequenced.
38:43
And today is the big day, ... ...when I get to see the results.
38:50
So Richard, it's a long time... ...since you were in Oxford and... ...we took an armful of your blood. We've had a team busy working since then, ...
38:57
...trying to extract the DNA and... ...reconstruct your genome. To understand my genes, ...
39:03
...Gil McVean matches them... ...against the human reference genome. A composite of anonymous donors,...
39:09
...that took 10 years to decode and construct. And what we're really interested in is not saying where
39:17
you agree with this reference but finding places where you differ in that we find over 4 million differences
39:23
between your genome and that reference we have about 50,000 variants we've seen
39:28
you for the very first time completely new to science it is extraordinary that
39:33
this enormous quantity of data reveals incredibly precise details about me
39:39
elements of my private world that I've never shared with anyone before or known
39:44
myself we have a classic European mutation that means you got bunny ear wax you've got
39:50
another one which means that you can smell asparagus in your own urine you've gotta another one that means you
39:55
can taste broccoli they sound frivolous but at the same time they probably point
40:00
to an evolutionary process and that's probably to do with your ability to detect toxins know you there are certain
40:08
plants have different toxins across the world there's local adaptation to the toxins that you would you need to be
40:14
able to recognize to survive that buried in my genome is the story of my
40:19
own survival but also clues about how i made i do I have ticking time bombs in
40:27
my genetic code you have roughly hundred mutations which had been seen before and
40:34
in clinical settings and have been reported as being associated with the disease having these mutations doesn't
40:41
mean you definitely going to get the disease it just alters your chance of getting that these are the variance that
40:47
you carry which had been associated with a whole range of common disorders
40:53
everything from cancer to type 2 diabetes and to schizophrenia let's just take an example of this zoom
41:01
in on chromosome 11 you've got a mutation which the literature tells you is associated or causes porphyria which
41:08
is at the disease that people hypothesize for a while cause the madness of King George it's a nasty
41:15
disease you would know if you had it you should have like a seventy percent chance of getting for so I've dodged
41:22
that bullet but there are other threats it's so impressively precise my genome
41:29
reveals that if i smoked I would have been in the most high-risk group for developing lung cancer like here of
41:36
changes your genotype doubles your risk of getting lung cancer but actually the way it does it is from doubling your
41:43
risk of smoking in a particular way so this this variant influences your risk
41:48
of getting lung cancer because it changes the way people smoke the smoke deeper breaths they smoke closer to the
41:54
end of the cigarette what it actually does is change or smoking
41:59
how fascinating it so it so it picked up as a gene for lung cancer but the method
42:05
of transmission to the method of effect is bio smoking behavior exactly
42:11
this raises an obvious question of whether you've ever smoke do you do like the smell of wood I've never smoked that's good so but
42:17
don't take up smoking is my advice it seems to me to be utterly astonishing that it's possible for scientists to
42:25
taken an individual and to detect apt these millions of digital pieces of
42:33
information to actually read it out as though it was a computer disk
42:38
well here it is then here is your genome look after it thank you very much I'm have delighted
42:45
to have it and thank you so much for all the amount of work that you and your colleagues of have put in and when I
42:51
look at this this little box here in what it contains is all the information necessary to make not quite me to make
42:59
an identical twin me and I think that sir and an astonishing thought and thank
43:06
you very very much for this in a pleasure
43:18
as we come to learn more about DNA our relationship with death is bound to
43:23
change and as more of us have our
43:29
genomes analyzed will be able to avoid those ticking time bombs contained in
43:34
our codes that killed our ancestors after they reproduced
43:47
this is my genome my whole Jima and strangely enough portions of my genome
43:54
behind that door behind there is the Dawkins family vault
44:00
this has been the Dawkins church since the 17 twenties and in there are 20 of
44:06
my relations many of them my ancestors and they have contributed some of the genes that are inside this little silver
44:14
box at the top next to the top there Henry Dawkins and then three down his
44:22
wife lady Juliana Dawkins they are my four grades my great-great great-great
44:28
grandparents 164th of the genes inside this little silver box come from Henry
44:35
the bottom of this column here the middle column is another Henry his some he has contributed 132nd part of the
44:45
genes inside this hard disk unfortunately the door can't be opened it hasn't been opened since I think 1919
44:52
they've lost the key nobody knows how to open it there are some slots in there but I should never
44:58
occupy one unless they can get the door open what would be rather nice would be if we could somehow post this disc in there to
45:06
rest alongside my ancestors but the jeans the set of instructions inside us
45:13
don't rest just as they have come from our ancestors before us so 22 they march
45:20
on into our children and their children's children our genes are a kind of archive of the
45:30
remote past and they go through us to the remote future Henry Dawkins maybe my
45:37
for grades grandfather and he's put some jeans in here but my 200 million greats
45:43
grandfather was a fish and by the way the same fish was your 200 million greats grandfather to amazingly even he
45:52
has put some jeans in here and they too have a chance of going on to the remote
45:58
future our genes are in a sense immortal
46:03
that's not comforting in the way the soul is supposed to be but it is a
46:08
wonderful thought and it is true we may
46:13
argue about whether we have an immortal soul that survives our death but one
46:19
thing science tells us for sure is that if there's anything that's immortal in our bodies
46:24
it is our genes
