Doing work which has to be done over and over again helps us recognize the natural cycles of growth and decay, of birth and death, and thus become aware of the dynamic order of the universe. "Ordinary" work, as the root meaning of the term indicates, is work that is in harmony with the order we perceive in the natural environment.
Work helps prevent one from getting old. My work is my life. I cannot think of one without the other. The one who works and is never bored is never old. A person is not old until regrets take the place of hopes and plans. Work and interest in worthwhile things are the best remedy for aging. ... With age your facility of expression and perception diminishes. I have almost nothing left but time. But if I can be of service, I would like to go on living.
