As you get older you start losing hair where you have always had hair, and you start growing hair where you never had hair before. It's a very scary moment when you realize you have to start trimming ear hair.
Hair is on your body for a reason, women should not shave their pits, legs, etc, and men shouldn't shave their face. Trimming is ok, so haircuts and a nice trim of the ol' beard ain't bad.
this is just an opinion of course.
the great thing about body hair is that it grows back. one day you can be hairy and the next you can be shaved. thats the beauty of it. mix it up!
