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.

I thought this feels like a different Jenna to the Jenna who came into my studio back in 2020.

And then as I started reading and listening to some of your other more recent interviews, I thought, wow, you've been through some quite significant life changes since I last saw you, which I think is beautifully reflected in your writing.

Let's talk about that as much as you're open to share as to what has changed in you since our first conversation.

But also it makes me think of like almost the middle part of the book where you talk about midlife and midlife being this really important, I guess, stage in our life where you actually say, don't you, beyond the age of 40, there's a meaningful change in your biology at 40 as well as perhaps your psychology.

So can we sort of go, I was going to go into this a bit later, but I think now seems like the right time to go in there.

Yeah, thank you for sharing that.

It definitely helps me understand how and why the tone of this book, I would say, is quite different from your first two.

And it's certainly where I'm at in my life.

So I very much resonate with this.

As I said to you when you walked into my house this morning, there's less of the what.
