My body doesn't do that

So, I have a pretty good body, as far as bodies go. And I'm not talking about "hotness" but function. It walks, runs, breaths, thinks, digests, circulates blood, and most amazingly it makes babies, pushes them out, and makes milk for them. I don't have any health problems, I am all around pleased with the body I was given.

But there's one thing my body doesn't do.

Dance.

Just watch these people. Nothing fancy. But I watch in fascination and awe because there's no way I could ever do that. How do they move their bodies that way?

I used to go to BodyJam at my old gym which is dancing for exercise. It was sooo fun, but I never looked smooth. I was always one move behind and if I ever was with the instructors, it took my complete concentration and effort. Whew. Is this a case of nature or nurture? Do I not know how to dance because I don't have that innate sense of rhythm and movement? Or do I not know how to dance because my parents don't either? Sigh. I shall never know, doomed forever to watch others bust a move while my own paralyzed limbs mock me by staying perfectly still by my sides.
