Genetically, my maternal grandfather went bald in early middle age, I think. However, all of his brothers still have a full head of hair. All eight or so of them.
The thing is, I've never seen anyone else with quite my style of hair. It's usually called a Jewfro by others, but it transcends that a bit without getting into negroid territory. My high school soccer coach always told me that he had hair just like mine, and he went bald in his 20s I think.
OH GOD PLEASE NEVER LEAVE ME!
