I have heard the saying "life is a game" repeated often. But what are the characteristics of a regular game, and in what way is life similar to a regular game? Life is a game if it satisfies the following conditions (wikipedia definition):
fun: the activity is chosen for its light-hearted character
separate: it is circumscribed in time and place
uncertain: the outcome of the activity is unforeseeable
governed by rules: the activity has rules that are different from everyday life
fictitious: it is accompanied by the awareness of a different reality
I don't see how life can be a game using this definition. In what way is life a game? Do we need a new defintion of a game to consider life to be a game?
