Premature graying runs in my family. I had a lot of gray streaks in my hair at age 23 and my sister was totally gray at age 17. Unacceptable for both of us. It's a personal choice, obviously, but still being out there in the work force, I want to look as young as possible. It may be illegal to discriminate on the basis of age and they may never tell you that's the reason but it's done every day. And I feel younger when I look in the mirror and don't see those pesky reminders that my calendar keeps losing pages. Plus gray hair often becomes unmanageable, kinks a lot and causes the rest of the hair to look unruly. I have a friend who is 63 and has long gray hair and she looks to be 75. It's her choice and she's happy w/it so it's her friendship that I care about, not her hair. If you're pleased w/your hair and how it looks and how other people react to you, then you go, girl! :)
