Just think what agility, mental and physical, like in this video, found in almost every one of us, can acheive when brought to bear on our problems. Even the largest of them:- our oppressive economic system.
I once made the mistake of pointing a DDR freak to see this video. She was disgusted. it's "Pump it Up" not DDR. Apparently it's a clone/knockoff of DDR and so therefore it's immediately recognized as inferior.
