There is a fine line between quirky and out-and-out crazy. With 18 scientifically based quizzes, Andrew N. Williams helps readers decipher whether they're "normal," toeing the line, or far past it.  Developed by psychologists to analyze human behavior, the quizzes allow readers to discover if they (or their friends and family) are:  - Sex addicts - Obsessive-compulsives - Food freaks - Thrill-seekers - Hypochondriacs - Fetishists - Paranoids - Imposters  Plus the book includes descriptions, in layman's terms, of more than 80 specific quirks, illustrated with real life examples. Readers will marvel at stories of people who:  - Crave dirt-and eat it by the handful - Are afraid of doughnuts because they can't see what's inside - Lie about deaths in the family-to collect sympathy cards  But Are You Crazy? is much more than a party game, offering helpful insights for dealing with other peoples' crazy behavior as well as one's own insecurities and phobias.
