I have never seen my dad without a brutal mustache. dude has steadily rocked one since the mid 70s without getting rid of it, so i think it' about as much of a part of him as any other body part. i think that's cool.
on the other hand, i can't stand my facial hair. my girl likes it but i think it looks like shit. clean shaven feels the best to me, and shaving should be ritualistic for a man. just like going to the barber (NOT a fucking salon) or cleaning your guns.
