Some observations extend back many centuries when the Roman physician and philosopher Galen stated that "melancholy" women were more likely to develop cancer than women with a "sanguine" disposition.1 Other historical observations include the doctor who treated the author Alexandre Dumas for stomach cancer. This doctor believed that the principal causes for cancer were "deep sedentary study" and the "anxious agitation of public life."2 The Buddhist teacher Dogen observed in his Shobogenzo that people are less likely to be sick when life is removed of its complications. Although these ideas were primitive in their nature, modern research has started to show that these observations were not far from the truth.
