Something as superfluous as "play" is also an essential feature of our consciousness. If you ask children why they like to play, they will say, "Because it's fun." But that invites the next question: What is fun? Actually, when children play, they are often trying to reenact complex human interactions in simplified form. Human society is extremely sophisticated, much too involved for the developing brains of young children, so children run simplified simulations of adult society, playing games such as doctor, cops and robber, and school. Each game is a model that allows children to experiment with a small segment of adult behavior and then run simulations into the future. (Similarly, when adults engage in play, such as a game of poker, the brain constantly creates a model of what cards the various players possess, and then projects that model into the future, using previous data about people's personality, ability to bluff, etc. The key to games like chess, cards, and gambling is the ability to simulate the future. Animals, which live largely in the present, are not as good at games as humans are, especially if they involve planning. Infant mammals do engage in a form of play, but this is more for exercise, testing one another, practicing future battles, and establishing the coming social pecking order rather than simulating the future.)

No child should ever be too sad to play.

Life always gives us another change: It's called "To Move On".

Very well. He'd lighten up. As a matter of fact, he felt as light as the bubbly froth that flew from the lips of the waves. Whatever else his long, unprecedented life might have been, it had been fun. Fun! If others should find that appraisal shallow, frivolous, so be it. To him, it seemed now to largely have been some form of play. And he vowed that in the future he would strive to keep that sense of play more in mind, for he'd grown convinced that play--more than piety, more than charity or vigilance--was what allowed human beings to transcend evil.

LIfe is just a game of chance, a dance with fate if you let it be so. Or you could chose to play by your rules to win.

He talked about luck and fate and numbers coming up, yet he never ventured a nickel at the casinos because he knew the house had all the percentages. And beneath his pessimism, his bleak conviction that all the machinery was rigged against him, at the bottom of his soul was a faith that he was going to outwit it, that by carefully watching the signs he was going to know when to dodge and be spared. It was fatalism with a loophole, and all you had to do to make it work was never miss a sign. Survival by coordination, as it were. The race is not to the swift, nor the battle to the strong, but to those who can see it coming and jump aside. Like a frog evading a shillelagh in a midnight marsh.
