When the opportunity to interview one of the leaders in integrative and holistic medicine came up, Dr. Jaffe, Dr. Kahn packed his recorder and met in Philadelphia at a meeting they both were speaking at. Dr. Jaffe is a hero from his training at the NIH, to his research, to his establishing one of the best labs (www.elisaACT.com) and supplement companies (www.perque.com) worldwide. They talk about physical training, markers of aging, and his program for longevity. You will want to check out his website at drrusselljaffe.com.
