You have to have high levels of bodily energy and not everybody has it. I’m not physically strong, but I have very great intellectual energy, I always have. I’ve been able to work all day. I don’t have to get up and get a drink of water or watch TV for half an hour. I can literally sit and work all day once I get going, not everybody can do that. It’s not a moral issue. Some people seem to see that as a moral question. It isn’t. It’s a question of body type and temperament and energy levels. I don’t know what makes us what we are.
