What makes them particularly impressive to me is the amount of automation that must've happened to let them do these things (the muscles are impressive too - there's a guy who spins his body on his hand while "jumping" with it rhythmic - crazy!). I wonder what goes through their head when they do these dances - is it so automated that they might dissociate completely while doing it? Given the great space of possible human movement, do they plaster over the wrong bits to the point where they could sleepwalk through it?
Speaking of which, I think I'd like to learn circular breathing.
