I'm 200 right now, so I was super skinny.

You know, doing chronic endurance training.

And I didn't mention that with the training piece, but that's like running from a lion all day, right?

So nature doesn't want to bring babies into the world in a time of constant running from lions.

So you see a down regulation of fertility

and testosterone in that environment and so when i finished like 20 years of just masochistic endurance racing i was in the upper 200s low 300s whoa wow that's low yeah i thought you were going to say the opposite night and day difference now it's a nice thing yeah you'd think like yeah out there you know doing the david goggins thing and just like pounding the pavement maybe that's going to increase your virility and your testosterone but

So my testosterone is higher than David Goggins.

Let's go.

Yeah, well, I don't know what that is.

I mean, you look at a picture of an endurance athlete and a sprinter, I mean, which one looks like they have more testosterone?

True.

Which one looks more anabolic?

So there's a trade-off.

Damn, that's crazy.

That's high VO2 max, though.

Yeah, I guess VO2 max is important, too.

Yeah, what was that movie back in the early 2000s with Clive Owen?

Children of Men?

The Children of Men?

I think that was another, but it's basically like global infertility event, like all of a sudden, like, grow women to have babies.
