Although I can still grow a fairly good head of hair, I keep my head shaved most of the time. I started this while working in a particularly hot, dirty enviornment some years ago and found that I liked it. I also do it to give hope and support to the guys who do those intricate and (in my opinion) ridiculous looking combovers to hide male pattern baldness, that it's OK to just shave it and embrace their baldness.....lol. Also, I hunt alot and with a shaved head, I can instantly detect which way the wind is blowing to prevent scent detection!
