It's a common fact that everyone poops. This witty, illustrated description of over two dozen types of poos (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. Our favorite poos are: The Log Jam, The Glass Shard and The Rambo Poo, . . . but the list goes on. Who knew you could learn so much from your poo? Written by Anish Sheth, M.D., a gastroenterology fellow at Yale and Josh Richman who has an MBA from Stanford University. Also available is your very own POO LOG, so you can keep track of your turds each day, so you can delve into the mysteries of your digestive system even further. dimesnions: 4 x 6 x .25
