Real men take their road rash in stride, without the need for shaving. You know, like real men. :D Besides, I call B.S. on the road rash being less severe without hair. (maybe cleaning it but I've gotten some good road rash and I always shave my legs) By all means... trim your nose hair, ear hair and Andy Rooneyish eyebrows.
My legs and arms stay the way they are...but the good lord as my witness, if my back EVER looks like this, the razor is coming out.
I don't think I'll ever have to worry about looking like this. Hell, it takes me about 5 days to grow a little scruff on my face. I call it my 5-day shadow. :D
