I didn't start ballet till I was 17, I'm 5'10" and a runner ... all bad ingredients for a ballet dancer. However, 5 years later I'm still dancing. It's going to be harder for you than the bendy little 6-year-olds, but I love it, and have actually quit singing and acting since I started in order to focus on dance (I study modern and jazz as well). Go for it, and good luck![/i]
