Guilty! 6'3" and 150-160lbs most of my life. Turned 30 and I've shrunk to 6' 2.5" and grown to 175-180lbs. I'm waiting for ear hair. lol
Ten years ago, I was twice your age. No ear hair so far, so you should be good for awhile yet. The metabolism is no longer stuck at warp 7, though - I'll have to start exercising soon.
