Dancer's Life.

I have been dancing for only a few years, but I learned very quickly how hard of a sport it can be.  You have to have good endurance, because you work from the beginning of practice to the end, no stopping.  I have played other sports in my life, but dance is definitely the hardest.  It can also hurt, because as of right now I have bruises and bumps all over my kneecaps, as well as bad knees in general. However, it's very common for a dancer.
