I don't know. I agree with you.

Couldn't even get up to go to the bathroom. This is the extreme. They wanted to really understand what full sedentarism did. What happened? Oh, so their cardiorespiratory fitness was just, it went, it was just shot to the ground. I mean, it was terrible after three weeks. But here's the real kicker. So, Ben Levine was a young boy when this was done. This was done by his mentors, okay?

You know, fast forward 30 years, okay? They found these same 10 guys. They found these same 10 guys, okay? Now, here's Ben. This is Ben's being involved in this study. They get these same guys, and they measure what 30 years, because they have all their data from before the bed rest, right? They measure what 30 years of aging does on their cardiovascular system.

And do you want to know what is insane? 30 years of aging was not worse than what three weeks of bed rest did.

And do you want to know what is insane? 30 years of aging was not worse than what three weeks of bed rest did.

It was not worse than three weeks of bed rest in terms of their cardiorespiratory fitness, which I personally think is one of the best markers for longevity that we can measure, VO2 max.

How often do you test it? Good question. Okay. So embarrassingly, I do an estimator for it. So how do you measure VO2 max? Okay.

You have to go into a lab. You have to really precisely measure it. You get a lab and you can Google whatever. But you're doing your Apple Watch. I do my Apple Watch, but also there's something called the 12-minute run test, which... is a good way to do it. It's actually a little better than the Apple Watch, I think.

So what you'd have to do is, because your Apple Watch is measuring, so I do a lot of running, but I do a lot of trail running. And trail running is like hills, okay? And you run slower when you're running on a hill, right? And so your true VO2 max, you want to have a flat surface where you're running. So you have to find like a track field and you want to run

as fast as you can maintain for that 12 minutes. So it has to be a sustainable 12 minute speed. You don't want to go too fast, but you don't want to go too slow. Right. So it has to be like a sustainable speed that you're really pushing hard, but you're able to sustain that for 12 minutes. And you do that 12 minute run test on a flat track.

So you can do it on a treadmill also, right? Yeah.

So you can do it on a treadmill also, right? Yeah.

Yeah. Yeah. You just have to have measure your distance. So measure your distance that you ran and the time. And then there's an equation you can plug it into. It's called the Cooper test. And that'll give you pretty much that's what your Apple Watch is doing. Yeah. Or your whatever device that's measuring VO2 max is doing something similar.
