One of the challenges is that the richer we are, the longer we live.

That really has to do with our aging population.

In my lifetime, former colonies gained independence, and then finally they started to get healthier, and healthier, and healthier.

They reproduce. That's population biology 101.

Sea turtles have a long lifespan.

Talk about survival advantage!

For 60 years, the ring lay quiet in Bilbo's keeping prolonging his life, delaying old age.

Attaboy, County, old boy, old boy, County.

So what did Jeff and his team learn from this prototype?

The first one I'm going to talk about is how to get from a relatively modest amount of life extension which I'm going to define as 30 years, applied to people who are already in middle age when you start to a point which can genuinely be called defeating aging.

Seriously, how long you think they got?

All the green Latin American countries are moving towards smaller families.

Well, that's good news. That'll make both our lives a lot easier.

Costa Rica average life expectancy is 78 and a half years.

Maximum lifespan

Minimum lifespan

Fouryear lifespan.

But when consumed in reasonable doses, and at the right age, wine can be very good for health.

Why is this suddenly being like this?!

Extension of lines

Sometimes people just die.

Of how much more worth are you than the birds. Which of you by being anxious, can add to the length of your life?

And these people suffer.

For reversing disease, that's what it takes, but if you're just trying to be healthy, you have a spectrum of choices.

Women usually live 10 years longer than men do.

But what would be so amazing about this?

Live long and prosper.

(Laughter)

Peace, and long life.

Many of the talks yesterday talked about improving the quality of life, and reducing poverty, and essentially increasing life expectancy all around the globe.

And mutations that damage the TOR gene just like the daf 2 mutations extend lifespan in worms and flies and mice.

Which, by chimpanzee standards, is very good indeed.

Here was a country with some of the world's best health outcomes,

So, we turned to the data again.

So people take it to prevent organ transplants from being rejected.

The lifetime of a butterfly is three days.

Butterflies live for three days.

He was just old. It was just his time.

But not to last.

Well, we're no genetically hardier than our ancestors were 10,000 years ago.

Suicide is a leading cause of death in the country with the longest life expectancy.

How long shall I live?

Well, maybe it was just her time.

It's on its last legs.

Ultimately the reason the don't live so long is because they have different genes, that would force them to have a different body that ages less well and therefore age is more rapidly.
