i have a beard that is longer than most people
Well, in humans only adult males are typically able to grow beards. So you must be an adult male :D
:) yes I am 
Haha, well it is a vestigial trait from back when humans were covered in hair like gorillas
I always wonder why the face we have a beard when it is not necessary anymore
Yes, it's just leftovers lol. In some cultures, though, beards are associated with poor hygine or being a savage. I wouldn't recommend vacationing in those places.
