I find yoga is an excellent way to relieve stress and stay in shape.

Speaking in front of an audience is one the top stressors and those butterflies in the stomach are always there. I have found that the butterflies are not a bad thing as long as you can get them to fly in formation and control them. I think this is better than the old tip to think of your audience naked!
