The Dalia Lama, when asked what surprised him the most about humanity, aswered MAN.
Because he sacrificies his health in order to make money. Then he sacrificies money to recuperate his health. And then he is so anxious about the future that he does not enjoy the present.
The result being that he does not live in the present or the future. He lives as if he is neveer going to die. And then dies having never really lived.
