I seem to be in the minority... I started going gray in my 20's and started coloring my hair in my 30's.

I'm 53, and have not figured out how I will eventually switch to gray, but I've been reluctant to do it yet, because I teach middle school and also I perform regularly with a band. In both of those arenas, there are advantages to not looking too old... and I would definitely look a lot older with the amount of gray I have.
