Why do men go bald on top of their heads but not the facial hair? (self.asklemmy)

I guess that goes for eyebrows and other body hair in general, but it seems like hair loss with age is very specifically only on top of the head and nowhere else.

Yeah, fractured ceramics can be more than sharp enough - really metal is a downgrade at the microscopic level. The trick is that it's pretty hard to get a totally straight edge. The Aztecs did it, but it sounds like it required a mass-produced supply chain of some unknown kind (and I'm not even sure if grinding has been ruled out).

I miss a strip on on my non-dominant side every once in a while using power clippers, and we're talking about a wiggly little stone scraper. Primitive people spend all that time we spend on books working with their hands and body instead, and would have a ton of family around, so they'd probably never have to do themselves, but it's still kind of impressive.
