The Nature of Cool

Somewhere in radioland I heard a discussion of the definition of 'cool'. I think they all missed the boat with their answers. To me, Cool is the opposite of Spazz. The way it came to me is in the reaction one has to the pinball heading for the flippers. Either you are cool and wait for the right moment to flip the correct flipper or you flail like a spazz flipping both flippers together wildly missing. The concept scales up to life, approximately.
