Before clicking on the link I assumed circumcision actually. Basically half the population has got it done :D

(I know that the rate has lowered over the last years, but USA still has what... 85+% ? Even higher in South Korea e.g.)

It's falling pretty quickly, down to about ~60% of male infants as of 2022. General prevalence is higher (because that's how decreasing rates work), somewhere around 80%, but I'd suspect it's highly regional.

That's another good guess - whatever you think about it it's the surgery that's probably closest to being "routine".

If you wait a little it will go down on its own.

I was thinking maybe wisdom teeth extraction.

Common, but a lot of people never get it. Either they didn't grow wisdom teeth at all, or they aren't pressing into the rest of the teeth in a way to cause a problem, or they lack dental insurance.

It's one of those super low-priority surgeries for most people. I'm very glad I got it done myself, though!
