The man who introduced the world at large to the unconscious meanings of our gestures and expressions in Body Language (1970) now looks at what you can do with your body on a conscious level, and the result is small-talk gone mad. After speaking with hundreds of self-absorbed people about diets, sex, exercise, and other fashionable ""health"" topics, Fast culled the ""most unusual. . . whose tricks and techniques were available to all of us,"" and reproduced the dialogues with a verbatim flavor that often chokes (""Nutritional density. It has a nice solid sound to it. What does it mean?"" chirps one wide-eyed calorie counter). Some of the stories have some intrinsic interest: the television repairman who found a way to diet without letting his family know; the man who takes the subway home to his wife at lunchtime for a ""sex matinee."" But most of the people who sprint through the book's 50 or so topics seem bent on finding the one mystical muscle to bend or relax, the best way to lose weight without sacrificing avocados, or any way at all to open the sexual horizons of the breathlessly naive Fast.
