Currently I am writing a chapter for the Magic Moments book on qi energy, the so-called life force energy that underlies tai chi, Qi Gong, and various traditional Chinese medicine techniques such as acupuncture, acupressure, and moxibustion. It has been fascinating to read through the literature and to interview several trainers. I have done tai chi and Qi Gong for many years and personally find them very useful. Fitting them into a evidence-backed framework can be a little more difficult to say the least.
