Existence, as we know it, is full of sorrow. To mention only one minor point: every man is a condemned criminal, only he does not know the date of his execution. This is unpleasant for every man. Consequently every man does everything possible to postpone the date, and would sacrifice anything that he has if he could reverse the sentence.
