Stress Reliever

What is your favorite way to relieve stress? I read and run. I can't run fast or far, but I am a champ at reading. My first pick for distraction is mystery fiction, often things I've read before. I eat too. I wish I was one of those people who cleaned their house or ironed when stressed. I'm more likely to pick up a book by Agatha Christie and chow on M&M's. What do you do?
