AMSTERDAM - From the age of twelve until the age of twenty-two, Erwin Roebroeks was in the grip of a compulsive disorder. He showered eight hours a day, drank soapsuds while wearing surgical gowns, and cut open his skin to be able to clean the inside. At first, the medical world wrote him off. Roebroeks will never get rid of his severe obsessive-compulsive disorder (ocd).
