I will be the first to admit that I am no expert on this subject, but I cant help but think about the video of bear cubs sliding down a snow covered hillside. It seems that most animals at play we can find some justification for, fawns running and dodging can be used to escape a predator or the kitten stalking through the tall grass to ambush his litter mate is obviously a predatory instinct for catching game. Bear cubs sliding down a hill and rushing to the top to do it again shows a certian ammount of joy this obviously fits into a different context.

Along the same lines as a species have humans evolved to the point where some of our natural instincts have been lost? Why will a 4oz blue bird attempt to drive away a 3lb cat from its nest, while a human mother is capable of leaving an infant in a car in the supermarket parking lot on a 100 degree day? Or are there just oddities in all species?

Like I said I am no expert.

But a great topic
