James ‘Double Helix’ Watson on happiness (from the NY Times)
‘I’m not politically correct. And I have an odd theory on happiness, and it bothers people. My general theory is that happiness is a reward for an animal doing what it should be doing. So if a horse runs, it feels happy. Or if you are too thin you can’t be happy, because evolution wants you to be tense and anxious, trying to wake up in the morning looking for food. So I was just saying that happiness comes only when you are doing things that are good for you. But to tell a woman that she can’t be thin and happy unless she exercises, they don’t want to hear that! ‘
Makes perfect sense to me.
