I don't understand why people excersize. I mean why bother? The end is always death. Only diff is that people who are healthy live longer. I know some old people who are thin and they are very sick. Where other people who have enjoyed their lives to the fullest, ate what every they wanted, didn't care about weight gain, sat all the time, smoked drank until they died. They were very happy. They didn't live long, but I would rather be happy, then to spend my life excersizing and being healthy. Someone explain it to me. why excersize? When ur going to die anyway.
