Ladies, when did you start shaving your legs?

I saw a commercial last night for one of those child pageant reality shows, and one of the scenes they showed was a mother shaving her 7 year-old daughter’s legs. I found this very disturbing. I started shaving at about 11 1/2, in sixth grade, and even that seems pretty young in retrospect. How old were you when you started shaving?

*edit: IF you shave at all, that is.
