Okay, Emily, welcome back.

So excited to be here for this one, Will.

Health span, this is a big one.

You know, it's funny, I think you and I have both seen the designs or ideation of a feature long before the feature is actually built. And I remember saying to

the data science teams and the product teams, like when we had kind of finalized what we thought

this should look like in a final form, that I thought this was going to be as successful a feature

for WOOP as the recovery score, which was a pretty big statement. And I mean,

we're only now shortly into having launched it, but I think we're already hearing some amazing

feedback. Let's start with what is health span? So health span is generally this concept of like,

we're all familiar with lifespan, right's how long you live but the place

where science and medical advancements have made the most gain is improving lifespan without

necessarily improving health span so you can think of health span as this thing that's like up to

but not necessarily as long as your lifespan, which is where you're

living with health. And we know now that there's about a decade gap between health span and lifespan.

And there are so many of these like biological clocks or age markers that are out there that

are focused on lifespan. And we really wanted to zero in on what are the

things that predict health span and how can we measure your health span, not just like some kind

of clock of, you know, how long are you going to live or something like that?

And when you say a decade difference in lifespan versus health span, you're saying that people

will live 10 years longer than they're actually healthy

for. Yeah. I mean, you know, think about how many people spend that marginal decade of life,

you know, in an assisted living where they're not able to walk. They're not necessarily enjoying
