I've been able to grow a full beard since I was about 15. You'd think that's great, but at that age a beard is worthless but to make you look like a goober, and you get to know the joy of shaving daily. Forever. In my 20's though it came in handy for altering my look and attracting different kinds of women, and even now once in a while I say fuck it and let it grow for a few weeks and take it to work. It only takes about 1 week to grow the whole thing out, and 3 weeks for it to be full enough to trim and style. Again, in the long run way more of a pain to maintain, but at this point I'm obviously used to it. I will admit I don't envy men who can't even grow some fuzz, as it means they're stuck with the same face all the time.
