I set a goal for myself to live to be 122 and I pick the number because it's big

enough that it feels like a stretch it feels like a challenge but it's small enough

that I feel like it's very

realistic I really feel like I can get there and I really I like I like to set myself up

for wins so let's see how I do I think the real question the bigger challenge that

I feel and I mean this honestly is can I get to

122 with all my faculties in order that seems like the much bigger challenge at this

point I have three children I'm almost certain all of them based on the breakthroughs in medical science.

I think all of them will make it to over a hundred years of age.

What that means is there's a big shift in perspectives that all of us need to make in how we think about

aging, how we treat aging, and how we treat our bodies and our brains as we go

through life. You know if you look down at your sneakers I'm looking at

mine right now I'm hoping they last for another three months but if I needed

them if I was expecting them to last for another three four years three four

decades I'd have to do things really differently. So when I look at my

hair, when I look at my skin, my teeth, when I think about my mental capacity, my

brain, my cognition, I'm thinking about things with that number in mind and thinking, what can I really do to maximize not just my lifespan but my health span?

How can I live a life that's long but also young in terms of how I can behave and that's a big challenge

and that's something that I've been thinking about lately. My guest on this week's show

is David Sinclair, Harvard Medical School researcher.

There's a lot of work with genetics and the epigenome.

If you think of his analogy, which I really like,
