However, then simple tragic could be circulated again and again to ruin one's mind, one without his mind is also lose his joy of living like a human being. All emotional game eager to expos one's animality with some kinds of "stimulus + response" mode.

Managing the game rule actually is one kind of restraint before enjoying the passion which make you have the delusion that you are the game ruler rather than a drunker as well. Gamble also has its unwritten rule, more or less, trying to excited people to release the animality of human, although it's really a civilized game comparing to the boxing.
