ENTON, MO (KTVI-FOX2now.com): It looks like an ordinary yoga class. Contemplative. Disciplined. Serious. So what's everybody laughing about? Would you believe, nothing? It's called "laughter yoga" - exercise for the funny bone.
Laughter, scientists have discovered, can do as much good for your body as going for a run. Volunteers who watched 20 minutes of comedies and stand-up routines experienced a dramatic drop in stress hormones, blood pressure and cholesterol. Their appetite was also stimulated just as it is with exercise.
