If you want mortality in a nutshell watch the film 'Dead Man' with Johnny Depp. Watching it now and moping about life in general and how I'm going to probably die without my life ever being remotely how I wanted it to be. Stupid life. Its a privalege to understand the psychological and physiological workings of human life and a curse that the only way this happens is if you are more of an unwilling observer than an unthinking participant. Its a great film anyway.
