Kung Fu, for sure. I have always loved it, I have done it for a few years, and I will continue to love it forever. If my body would allow, I would do it all day, every day, and never stop. But, my body does not allow, and instead my bones are all twisted with birth defects, which is very depressing and sad. It has taken my one physically intensive activity that I LOVE away from me, and I won't even go into how I couldn't keep up in the army >.<. But, I have a good life, so I cannot complain too much. :)
Never give up!
