I like the concept of play as an evolutionary advantage. Might go along with what I was talking with Dr. Simmons about in that the Motor Program theory can hold ground if you break the movements down to a simpler and general nature. We then use various experiments of movement (trial and error, play etc) to achieve the desired result with this task and refine the movement firing pattern.

Keep focused on your goals Charlie my man and you will accomplish what you seek to.
