"Tai chi helps reduce stress and anxiety. And it also helps increase flexibility and balance. If you are looking for a way to reduce stress, consider tai chi. Originally developed for self-defense, tai chi has evolved into a graceful form of exercise that's now used for stress reduction and a variety of other health conditions. Often described as meditation in motion, tai chi promotes serenity through gentle, flowing movements." --Mayo Clinic
