Sorry, I forgot to mention that; you're absolutely correct, but that's for a tiny number of people who actually have some medical problem where circumcision is a viable remedy. I meant medical reasons for doing it to all male infants as some sort of preventative procedure.

Pre-puberty here, and as someone that was about 4 years old when my circumcision was done I can absolutely understand how ancient peoples would decide just to do every baby boy on the off chance they’d need it later.

True, during the healing process I had the same thought! Would have been rather more convenient to have just had it done as a baby even if I hadn’t needed it!

That assumes they don't screw up and completely mangle it. That happens from time to time.
