When you were in your 1st year of life, you could say that was year "0".
Actually that is very culturally determined. The daughter of my Thai girlfriend was born in 2005. This year she turned 8 years old, but got 9 candles on her birthday cake! In Thailand one gets best wishes for the next year of your life, not for the life that just passed.
A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
