What’s Your Poo Telling You? - Tapa dura

With universal appeal (everyone poos, after all), this witty, illustrated description of over two dozen dookies (each with a medical explanation written by a doctor) details what one can learn about health and well-being by studying what's in the bowl. A floater? It's probably due to a buildup of gas. Now think back on last night's dinner, a burrito perhaps?

All the greatest hits are here: The Log Jam, The Glass Shard, The Deja Poo, The Hanging Chad ... the list goes on. Sidebars, trivia, over 60 euphemisms for number two, and unusual case histories all make this the ultimate bathroom reader. Who knew you could learn so much from your poo?
