It's not like the people who are suffering from frailty and sarcopenia are out of sight because they're our parents and our grandparents.

We've watched it.

We've been to the movie over and over and over again.

We see how it goes.

And yet somehow we

either don't think it's going to happen to us or it somehow still seems abstract because it's so many years off.

I mean, what's your take on this overall challenge?

Luke Van Loon made a really good point when we spoke, which was when we draw the curve for how people lose strength and how people lose muscle mass, we draw it in a curved smooth line, which gives us the incorrect impression that this is a gradual and imperceptible changing physiologic process.

But he goes, that's because it's averaging everything.

If you zoom in and look at it at the individual level, it looks like this, exactly as you described.

Discrete periods of loss from which there is no recovery, because at the later points in life, it becomes very difficult to make those recoveries.

All of this, of course, points back to where we're going today, which is

When you are young, and young is 40, 50, even 60, you have to build up as much physiologic headroom as possible.

You have to prepare for the rainy day because the rainy day is coming.

It's not a question of if, it's simply a question of when and exactly in what fashion it will be delivered.

But you must prepare for this.

You must steel yourself for what is coming.

And you must build up as much muscle mass and strength and cardiovascular fitness as you can muster because the longer you can ride it out, the better you're going to be.

We've just talked about not going backwards, right?

Yeah.
