do you have a beard? I have trouble growing mine well
I do, actually! I learned about them since I could start growing one a few years ago. They're a vestigial trait back from when humans had hair on their entire body, like gorillas!
that is odd, I wonder why we evolved to only have it in certain places on our body, hair that is
Well, the evolutionary loss of hair is more founded in certain populations like the indigenous Americans and some east Asian populations. But European or South Asian, or even the Ainu, have retained the facial hair growing capabilities.
Yeah I have noticed for example, people in the middle east have beards at like 14 years old while mine does not grow
Well, it can be a blessing and a curse. There are different societal attitudes towards the male beard, and it often depends on the cultural-religious traditions and the current fashion trends of your era/area. So, even if you couldn't grow one, that might be okay in some respects.
