Aaahaaa.... What an interesting question. This question is both amusing and agonizing.
I worry about my weight. Constantly. I'm always thinking about food and how many calories is in it and how much I'll gain from it. I usually eat about 1200-1300 calories a day with a half hour of exercise. I'm a slave to the scale. But don't get me wrong: I KNOW how IDIOTIC and sad it is for a machine to determine my happiness for a day. :(
