Here is a nice article from the WSJ on qigong. I have practiced qigong since the 1980s, starting with Chinese teachers in Miami. I was able to deepen my practice during my years living in China and I swear by its efficacy. As many of you know, I have some very severe heart problems and I believe this practice has helped keep me alive, when by many doctors' accounts, I should have croaked years ago. http://www.wsj.com/articles/SB10001424052702304373104579107190526946048
