Do you disinfect a door handle before you touch it? Do you change your clothes several times a day? Do you wash your hands 60 times a day or more because you feel you are contaminated? If you answered YES to all of these questions, you probably suffer from a washing compulsion...or are at least on the way to it. And you wouldn't be alone in that. About a million Germans are plagued by thoughts of contamination every day and feel compelled to take action against it.
