The reason is because going to the gym is one of the best ways to manage negative a effect. And and people who don't have high negative a effect, they go to the gym, it's like, I don't feel better. I know I got slightly better biceps, but I don't feel better. You go to the gym because you feel better. But you don't know. So people will say, "Oh, it makes me so happy to work out." No, it doesn't. It makes you less unhappy to work out.
