This isn't an easy question to answer anymore.

Used to be that you saw a guy walking around with a shaved head, and chances were he was either an overzealous marine, a white-supremacist, or a neo-nazi fascist. He might have been a swimmer, but that's a pretty slim chance.

These days it could be just anybody, and it's not just guys.

The professional atheletes who kids idolize are shaving their heads. So are the kids.

Musicians who kids idolize are shaving their heads. So are the kids.

Many leathermen and butch dykes have been shaving their heads forever.

Married Orthodox Jewish women often shave their heads. It is very common for them to wear wigs, though.

And, of course, many people who are losing their hair (either due to male-pattern-baldness or as a side-effect of radiation or chemotherapy) and would just rather get rid of it all at once.

I shave my head.

Who am I? I'm a computer systems professional. I'm a leather daddy. I'm a costumer. I know doctors, bankers, retailers and educators who shave their heads. I know comedians and actors who shave their heads. I know artists and musicians who shave their heads.

As I said, it could be damn near anybody.
