But that makes a little more sense.

Yeah, it could be that. Yeah, it's something in the kind of breath holding aspect of extreme bouts of exercise is also contributing to that contraction.

Yeah, there's – it's stimulation of the vagal nerve that is in part triggering this response, which, you know, runs through your face. And so that's why the, you know, the facial immersion is crucial to triggering the response. But there is, I think, a component of if you're just holding your breath where that also kind of triggers it. So –

Um, but yeah, it's really amazing to think that as mammals, this evolved sometime so long ago that it's in, it's even in mice. They've done a study where they actually trained mice to dive and they could measure the mammalian dive reflex in mice.

Yeah, I mean, it's a great question. I don't think we really know. There's a – some people talk about something called the aquatic ape hypothesis that says that one of our ancestors – Sorry, I'm trying not to interrupt, but I just – someone – I've heard of the stoned ape hypothesis. Okay.

Yeah, I mean, it's a great question.
