A receding hairline is about the only aging issue I don't have. I'm starting to go a little gray at 50, but I've got every hair I've ever had. A guy who gave me a haircut when I was in my 20s said I easily had enough to cover the heads of four people and that he should charge me extra for having to cut that many and putting that much wear and tear on his clippers and scissors.
I've gone with a military-style buzz cut for about the last 10 years just for convenience, but I'm letting it grow back out now. I figure that since it's my only real physical attribute, I should flaunt it a little.
Before anybody gets too jealous, I'll add that I'm both fat and ugly.
