Obsessive Compulsive Disorder
International soccer star David Beckham's OCD expresses itself by an obsession with pairing items and organizing them by colour or type. According to his wife Victoria, Beckham has purchased three refrigerators so that he can have one for drinks, one for salads, and one for other foods. The items must be in even numbers, as well. "If there's three cans of Diet Coke, he'd throw one away instead of having three--because it has to be an even number."
