Then you hit a certain age, you decline in grip capacity.

And that is true for a lot of things.

That's your cardiovascular fitness.

It peaks at age 18 and then declines from there.

And so we've tried to identify the peak age

health level of every category of every marker.

And we try to peg that.

So we say, what is peak cardiovascular fitness for an 18-year-old?

And then how do I achieve that?

So for example, my cardiovascular fitness is equal to top 1.5% of 18-year-olds as measured by VO2max.

We completed a test today looking at oxygenation of muscles.

And so that's also a marker of age.

So my oxygenation of my muscle is in the top 5% of 18-year-olds, elite swimmers.

And so we try to find peak levels and then peg my markers to that as best we can.

Yes.

I mean, if you basically said, a conventional wisdom would say, a 47-year-old could never be as healthy as a 16-year-old.

Now, in certain regards, that's

You're probably true, right?

They have the anatomy of a 16-year-old.

I have anatomy of a 47-year-old.
