WHY IS YAWNING CONTAGIOUS? IS IT TRUE THAT YOU SHOULD 'STRAVE A FEVER AND FEED A COLD'? WHAT IS A NORMAL PENIS SIZE? DOES CRACKING YOUR KNUCKLES GIVE YOU ARTHRITIS? WHY CAN'T YOU TICKLE YOURSELF? DR CHRISTIAN JESSEN, the unshockable presenter of the BAFTA award winning television show Embarrassing Bodies, and hit shows Supersize Vs Superskinny and The Ugly Face of Beauty, is always being tackled by strangers wanting answers to their most private medical questions. Like all doctors, Dr Christian finds people sidling up to him with their questions at parties, on trains, and even in the street. So why don't people ask their own doctors these questions in the more formal setting of the medical surgery? And what are the most common questions? Sometimes humorous, often surprising and always informative, Can I Just Ask? Provides the answers to all your questions, whether you have a worrying health dilemma or just a curious mind! www.drchristianjessen.com
