Based on the #1 "New York Times" bestsellers "Why Do Men Have Nipples?" and "Why Do Men Fall Asleep After Sex?," this calendar answers hundreds of fascinating medical questions that are just too awkward or embarrassing to ask your doctor. Like: "Can you breast-feed with a pierced nipple?" In most cases, yes--though it's a good idea to remove the jewelry first. And: "Do some people really have tails?" Not really--it's usually just an outgrowth of skin at the base of the spine. Plus pop quizzes, On This Day, DIY medicine, and Great Moments in Self-Surgery.
