When did we stop dancing?

As I was watching Cory "dance" to some Christmas music yesterday (he sways back and forth like a champ!) a thought struck me -- at what point in our lives did we, as adults, stop dancing? Cory dances every single time he hears any sort of music or tune. He gets a big ol' smile on his face and away he goes, swaying merrily until the music stops. He looks genuinely carefree and happy when he does it too. Don't you think that if we - society as a whole - danced more freely, we might be a happier group of human beings? Or maybe I'm completely off base here?! But think about it for a minute. I think part of the solution to fixing the world's problems may just be to dance!!!
