What Makes Life Beautiful?

In this world, beauty can often be found on a system whose state is somewhere between being ordered and random. The sunrise is a magnificent scene because it is on the threshold between night and day. The sunset is a splendor because it is midway between day and night. The amazing variety of species is partly due to minute errors in the genetic transfer of traits in the offsprings, thereby allowing a tantalizing animal and plant diversity. Music itself lies between a monotone and white noise, and the best of it is at its peak of complexity. Poems look like a jumble of words and yet it still makes a pretty sense. The best things hangs in the balance between order and chaos. Indeed, Complexity Theory specifies that any system functions at its best when in the borderline between order and disorder. Its almost saying that a little bit of chaos is a good thing. A little bit of 'defect' makes things pretty.
Is this the reason why some artists allow or induce some 'disorder' or drama in their life to make it more colorful? Is this why a husband and wife sometimes get into a bit of argument to learn more about their marriage and each other? Is this why we sometimes need a li'l bit of pain to 'feel' life? Could this be the reason why we do crazy stuff in order to escape boredom? Is this the reason why we laugh? Is this why we humans engage in extremely dangerous 'sports' activities so we can 'live on the edge'?
At the heart of the matter, we know that we are alive, but we know too that we are here only for a moment, and then gone...not knowing what will happen next. This makes life beautiful. Because "Living" is a tip-toe in the fine line between life, and death. Knowing the fragility of life, as well as its transcendence is what makes the glimpse of life worth an eternity.
