Break-dancing toddler

If this kid were mine, I'd be scared spitless of a broken neck. He will either be a professional dancer or a paraplegic (or a sky diver, or a gymnast, or a stunt man, or a race car driver).

And then you have to wonder what makes a kid like that? What combination of alleles and early exposure makes him want to do it? Maybe the larval stage of a type T personality? Some neurotransmitter is secreted into the oh-my-god-I-like-this part of his brain.
