Okay, so I'm 20 years old, and I have always, always admired dancers. And it was just recently that someone told me I should go ahead and actually dance. So, I've registered for my first dance class. I'm really excited but really nervous. I need advice. I've never danced before, like ever, and I don't expect to turn it into a career. However, I want to be decently good. Am I too old to be able to learn all the acro-tricks? Am I too old to get a "dancer's body"? I need to know what I need to buy.
