Tai Chi is a martial art, but most people think of it as a slow-motion exercise for health and meditation. In this podcast, Ken Gullette interviews Peter Wayne, a Tai Chi instructor and author of the Harvard Medical School Guide to Tai Chi. Peter Wayne is a researcher and an associate professor of medicine at Harvard Medical School who is involved in clinical trials of the health benefits of Tai Chi. So what do these clinical trials tell us? Is Tai Chi something special? Does it really have health benefits tied to the ancient Chinese theories of qi (chi), or are the benefits the same as you would expect from any low-impact exercise and calming, mindfulness practice?
