Bryan Johnson argues that sexual and reproductive health metrics like erection frequency and urine flow speed are reliable indicators of biological aging, but stigma keeps people from discussing them openly. Treating these taboo topics as serious health data, not jokes, reveals underlying problems and belongs in longevity assessments.
Okay, yeah. So, like, early adolescent, you're erect all the time. You know, you're walking in between class and you don't know what to do because, like, you gotta cover this thing up. Then you go and you gauge. You, of course, get fewer erections and they're less, you know, firm. And so nighttime erections are actually a meaningful biological age marker. And so we started to parse this out and we said, if you look at sexual health as a biological age function, what do you do? We did not have erections, and we just completed a bunch of other things. Like we did urine speed, void rate, whether I could empty my bladder. Of course, this is taboo. It makes people feel uncomfortable. It's something that people shy away. It's also a really good fodder for joking. And so I think that, to me, what's really happened with this fertility and this discussion of organ health is these uncommon topics bring to the surface these things that people are struggling with privately. They want to address it, and it just hasn't been safe to talk about it in any way.
