Yeah, I am insisting as much as one can insist that various people in my life read this book, including family members and other people, because, again, it's not just about people who want to have children or children.

who already have children, but fertility as a way of kind of knowing where one is in their health arc, in their life arc.

So if you don't mind, how should people think about fertility purely as a readout of health?

I mean, just how do you frame this for, like if somebody comes to you and says, listen, they have kids or they don't want kids or they're not sure if they want kids, but why use fertility as a lens on general health?

For women who are still of reproductive age, and I realize there's no strict cutoff, um,

we can and certainly will talk about what are the measures, direct and indirect, of fertility that can give them a window into their kind of health span risk factors, lifespan risk factors.

For women that have already reached menopause or in perimenopause, how should they think about fertility as a health marker?

Meaning if somebody is past the point where they can

and safely get pregnant, does that mean that their periods are no longer informative?

I imagine their periods features about their menstrual cycle are still very informative about their general health.

This is such an important theme.

And if I may, I...

I realize I have to be very careful to not draw parallels to men's hormonal health when talking about women's hormonal health, because it's not a one for one.

They're very distinct processes.

On the other hand, I think thematically what I'm about to say, I believe holds.

So hopefully it won't upset too many people, which is for many years now, for reasons that are unfair,

hormone replacement therapy sort of became widely available for men before it became widely available for women.

There were reasons for this.

We don't have to go into it, but they're the kind of obvious ones, that things were pushed to market more quickly.

and so forth, but there's been this idea, you know, there it's usually testosterone replacement therapy, right?
