This is very very very depressing. I finally find a sport I like to do, and now I'm going to get osteoporosis?!?!?!?

My only hope is that my many years of ballet training (with lots of jumping) has kept my bones in pretty good shape. I guess I need to get back to class, start jumping rope, and maybe take up weight lifting (which I only do every now and then when I get around to it). I really hate weight lifting...sooo boring!!

I was thinking about taking up jogging too, but then I'd probably get a knee injury!
