Exercise. It doesn't matter what: Karate, jogging, weights, skipping... but if I don't get my daily dose, things get nasty. I get surly and I don't really like being like that. In fact, just the other day Gib said to me, in a very serious and concerned tone "Beth, you're sounding quite negative today. I think you need to go to the gym". But with a daily work out, I feel happy, positive and often like a super hero. I feel totally invincible.
