Aesop, that great man, saw his master pissing as he walked. “What next?” he said. “Shall we have to shit as we run?” Let us manage our time; we shall still have a lot left idle and ill spent. Our mind likes to think it has not enough leisure hours to do its own business unless it dissociates itself from the body for the little time that the body really needs it.
