Andrew Weil is one of the most influential voices in alternative medicine today. He’s credited with establishing the field of integrative medicine and is the author of several best-selling books. In his latest, “Spontaneous Happiness,” Weil talks about living a life that promotes happiness and peace of mind. It’s a compassionate recipe for personal well being without the pressure to be happy all the time. Weil tells Steve Paulson that he's dubious about the prevelance of medically managed depression.
