Dr. David Spiegel, a professor of psychiatry and behavioral sciences at Stanford University School of Medicine. His groundbreaking study of breast cancer patients showed that women who had psychosocial intervention lived twice as long, after diagnosis, as those without that intervention. His new book, "Living Beyond Limits" (Times Books) covers current research on mind/body interactions, how to build sustaining support networks, control pain through self-hypnosis and detoxify fears of dying.
