And the reason why men have more hairy chests and arms and legs, ive heard, is because bugfree men are attractive, and apparently hair makes you detect it easier or something.. Altho it sounds rather wrong. There must be more reason for it than that

Ever herd the term neckbeard?

I said facial hair, not neck hair. Difference!

A full, well grown and groomed beard is a sign of masculinity. You know what I mean.

Weather it's well grown, that's just genetics. And you can't really groom a beard when it's 2 millimeters long.

Well yeah.. That's mostly the evolutionairy purpose for facial hair

Actually both are correct. Apart from the warmth it have always been a sign of masculinity.
