I do not spend any time thinking about death. My responsibility is to enjoy my life otherwise I need to step aside for another and let him use the valuable resources necessary to sustain it. It is a crime to remain alive and unhappy particularly in the western world given its toll on those of the greater world. To think about death when I am alive is selfish in the same way it is selfish to think about flying over Alaska at dusk when I am flying over Africa at dawn.
