LOL -- actually, I started going gray at 17. For me it's more indicative of stress than aging. :) I have a streak of gray hair by my right temple, and it was never there BEFORE grad school. *smirks* Ah well, that's what they make dye for. Gray hair doesn't bother me. Wrinkles? Those bother me. *sigh* I had no idea I was so vain!
