But yeah, it seems like these higher than average thyroid hormone levels, at least when the genetic cause was what we saw in the C-nomads, increased the size of the spleen, increased hemoglobin, increased hematocrit, increased red blood cell count.
Yeah.
Yeah. Yeah, and I don't think know how quickly the spleen reuptakes those red blood cells, but it does do that eventually. So maybe this is something that would be advantageous for short bursts or something like that.

I mean, I think there's a lot that we don't know about the performance-enhancing aspect of this, but that's really interesting because the work that we did in the mice where we replicated what we saw in these divers –
They had larger spleens, they had higher red blood cell count, but they did not have any change in erythropoietin, which is how we normally think about changes in red blood cell count. This is a drug that was really popular with cyclists for a while. People would self-dose with erythropoietin and it would increase their red blood cell count dramatically to improve their performance.

So this is like an erythropoietin independent mechanism of increasing your red blood cell count that could have an advantage in performance, I think.
Yeah, absolutely.
Oh, absolutely.
I haven't seen any studies that look at that, but it would be really interesting because, yeah, I mean, like you, I also would do anything to not get sick. And we do see in these populations a lot of older people who are continuing to dive. And there is a seeming health and robustness that I wonder if it's related to the activity of diving itself.

Swimming a mile is, yeah, that's quite impressive.
I would imagine.
Yeah, I mean, it's so low impact and such a natural way to, you know, to move, to exercise that, yeah, I think especially as we age, it would be a really wonderful way to stay fit and healthy.
