Canadian physician Gabor Maté is a specialist in terminal illnesses, chemical dependents, and HIV positive patients. Dr. Maté is a renowned author of books and columnist known for his knowledge about attention deficit disorder, stress, chronic illness and parental relations. His theme at TEDxRio+20 was addiction -- from drugs to power. From the lack of love to the desire to escape oneself, from susceptibility of the being to interior power -- nothing escapes. And he risks a generic and generous prescription: "Find your nature and be nice to yourself."
