Curves

If i was to represent my life in a curve, what would it be? Would it be a linear relation? If it were, would be increasing or decreasing? Would it be continuous? Would it be finite? Obviously, there will be a start and an end. Life starts at the age of zero and ends whenever i die. Which leads me to another important part of the graph, the axes. Would my axes represent life and happiness respectively? Not necessarily, I can draw it with the variables of sins vs good deeds. If i was to draw my life on this graph, it would look very similar to y=x however with minor fluctuations going up and down. Why is this so? I hold the belief of retribution to the means very dear. For every bad deed you do, a good deed would happen in exchange. For every good deed you do, you will have a flaw in some way. The minor fluctuation is due to occurrence at different times. They do not happen simultaneously, there is always a time and space. They will happen but at different times.
