Growing a beard

[CardSharpCook]

This is the first time I've let my facial hair go for more than 4 days since I was 16. How long should this take? It's been about 12 days so far. Looks like I haven't shaved in a week. I'm 25 now. My brother has had a beard (still has something on his face, I think) and my father has had a mustache, so I assume it is possible for me as well. Still, the forest is a bit sparse so far. How long must I look like an unshaven bum?
