And, you know, I mean, we see with competitive breath hold divers, you know, I've never actually been to one of these competitions, but I've read about them.

People pass out underwater all the time and they're, you know, pulled to the surface and revived.

But if you're a sea nomad diving in the middle of the ocean with no one nearby, nobody's going to pull you out of that water. And so you've just removed yourself from the gene pool completely, whereas someone who maybe has a variation or has genetic variation that's making them safer at diving might survive that.

Yes.

Yes.

Yes.

Yes.

Yeah. So this is exactly what gets people in trouble because, yeah, like, you know, we don't have a reliable sensor for when our oxygen is low. And so that happens to people underwater because that feeling, that wanting to breathe is a buildup of carbon dioxide. And so, yeah, people teach themselves to overcome it, like they're suggesting you do there.

Yeah.

And then, you know, you're underwater and you pass out and that's it.
