"To 'Air' is Human, Everything You Ever Wanted To Know About Intestinal Gas" is a uniquely informative entertaining and well-illustrated volume. Extensive knowledge about the physiology and science of the digestive process and intestinal gas is clearly explained. It covers everything you ever wanted to know about the fart, burp, and bloat, but were too embarrassed to ask. Intestinal gas has been produced and released by virtually every human who has ever lived, yet very few people have been provided with the knowledge that can offer comfort and relief. This volume is overflowing with practical information, fascinating facts, surprising trivia, and tasteful humorous insight about this universal phenomenon. A companion volume "Artsy Fartsy, Cultural History of the Fart", is a fascinating overview of the fart through the art, history, and literature of human society from antiquity to the present day. This is a seldom told but remarkable tale that informs, enlightens, and entertains. The last volume of the scatological trilogy is "The Scoop on Poop! Flush With Knowledge" This comprehensive and knowledgeable overview of the remains of the digestive process offers information that ranges from the potentially life-saving to the sidesplitting eccentricities and peculiarities of human nature. The wealth of valuable information and trivia in these volumes can sustain a long social conversation, or cut it short abruptly!
