For more than two years, the New York Timess science and health columnist Anahad OConnor has tracked down the facts, fictions, and occasional fuzziness of old wives tales, conventional-wisdom cures, and other medical mysteries, from which of your bad habits you can indulge (sitting too close to the television does not hurt your eyes) to what foods actually pack the punch advertised (you can lay off the beet juice!). Never Shower in a Thunderstorm will provide guidance and amusement to anyone who has ever wondered if the mosquitoes really are attacking her more than everyone else. (Yes, they are.)
