Question:

What are the side effects of becoming a ballet dancer?

Hello,

I want to become a ballet dancer, but my mom says that a lot of ballet dancers have health problems during their old age. Is that true? She says that the nerves on the big toes get damaged. I tried to Google it to see if anything was true, but I can't seem to find anything. Also, is it too late to start ballet lessons when you are in your late teens? What are some of the good ballet dancers/ballet companies out there? Is it expensive to become a ballet dancer? How many years does it take to master this art?
Thanks
