I think I find the benefits of exercise on my brain.

One of the kind of most salient benefits of, of exercise.

Um,

But I also just want to be strong, be able to do things and maintain health late into life so I can keep doing the things that I want to do.

So I think the way I approach training is try to optimize for performance, but not at the extent of sacrificing some of my other health metrics.

So I try to blend a little bit of the two.

75 to 80 is, you know, I've tested a few times throughout my life.

And so it's somewhere in that range.

But I mean... Maybe an elite level VO2 max, but my running times wouldn't be considered elite by most standards.

I think people will be pretty familiar with the term cardiorespiratory fitness.

It's sometimes used interchangeably with VO2 max or your maximal oxygen consumption.

It's kind of a very popular biomarker these days with, you know, like you said, and we'll talk about later, correlating with longevity and so on.

So cardiorespiratory fitness is sort of the exercise physiologist's measure of

Aerobic fitness, it's very popular as an endurance performance marker, or that's traditionally how it was thought of.

Because, you know, having a high VO2 max is kind of standard among high level endurance athletes.

But essentially what it is, is your body's ability to take in oxygen, take in air from the environment, distribute it to the rest of the body through your cardiovascular system.

get that oxygen into mitochondria and skeletal muscle, and then utilize that oxygen for energy in the form of ATP.

So it sort of represents your body's integrative ability to take in, distribute, and utilize oxygen.

And again, I think we'll talk about this later, but I think that's why it's such a potent predictor of longevity.

It's because
