I haven't clean shaven my face in nearly 25 years... It always causes ingrown hairs and razor bumps. I've always used clippers without a guard to "shave" my face, then do it again in a couple weeks.
Senior year was the first year we were allowed to grow a "neatly kept mustach", and I've had one since that peach fuzz that was coming in at 17.
After graduation I added the chin goatee and flavor saver, and that was pretty well par for I didn't start getting a real full faced beard until probably my early 30's... It was the first time my mustache connected to my chin. I thought it never would!
Now, in my forties, I just rock the full salt and pepper beard. Started letting it grow out for hunting a few years back, and just stuck with it. Makes me look like the puppa I am.
