What is aging?

What is aging?

Can it be slowed down or even stopped?

And are the anti-aging billionaires onto something with their longevity research?

Those are the questions we explored with the help of experts in the first two episodes of this series.

It seems very easy to make lots of money very quickly or a search algorithm could get you billions.

But aging isn't like that. It's complicated biology. It's an evolutionary balance that's been selected for over billions of years.

And I don't think these billionaires realize the time scales involved.

But while Silicon Valley Broes may be chasing the dream of enduring far beyond a normal human lifespan,

for the rest of us, our mortality isn't actually the thing we find

unacceptable. It's how we tend to get there, frail, infirm, unwell, in pain.

But is this just a reality we need to face?

We all sort of hope that we'll just stay nimble, agile,

active and healthy and then fall asleep and die in our sleep, and that will be the end of it.

But most of us don't age that way.

Can we change how we think about and experience the time in our lives that so many of us fear.

You can't just start that when you're old.

You have to start practicing that when you're young, staying connected, developing meaning and

purpose, finding things around you, being a part of a community.

And we'll finding new ways to tackle old age help us all, no matter how many years we've accumulated.

People talk about the gray tsunami as like this big public health crisis and it's going to be a disaster.
