I've been growing my beard for about 6 months. Don't even really know why because I've been clean shaven for a while now. I can grow a mountain man beard pretty quick so its big. It has gray in it mixed with black but looks really nice because I comb it a few times ery day with a beard comb. I usually don't mind it but this time its getting on my nerves so I'm thinking about shaving it off. Or should I grow it down to my knees? My wife says not to shave it but she's not my boss and don't tell me what to do.
