Dr. Rangan Chatterjee

is this idea that it's everything we do.

Everything we do, the food that we eat, how stressed we are, how much movement, is it the right kind of movement?

Even the way we talk to ourselves also impacts the health of our immune system.

Yes.

And I guess just to sort of make the full link, if someone has tuned into this conversation because they want better longevity, right?

They want to live well for longer.

you can't go far wrong focusing on the health of your immune system, can you?

Yeah.

And it really tells us something about the human condition, doesn't it?

This idea that, guys, we've already had it or we've already had...

a certain part of it, but are we maxing out what we've already got?

I mean, you talk in the book about health span and lifespan and soul span, which I love, but can you sort of help us understand, you know, why did you,

come up with the term soul span, and what is it about the current longevity revolution that we're not fully realising as humans?

No, I love it, Jenna.

It's exactly the kind of stuff I spend a lot of time thinking about these days.

And it was quite striking.

I'd be thinking about

reaching out to you for a few months, I keep thinking I must get Jenna back on at some point.

And then I got your latest book, Immune to Age.

And I was gripped from the introduction.
