Mary Roach is an intrepid reporter and author of several popular science books on such topics as cadavers, the afterlife, sex, and space travel. With Gulp, the reader is given a tour of the entire alimentary canal, focusing on its functions of eating (enhanced by the senses of taste and smell), digestion and elimination. Ever the investigator, Roach interviews the scientists who research the assorted subdivisions of these functions; and is able to present the facts in a comprehensible style and with a humorous touch. Find out the answers to such questions as: “why doesn’t the stomach digest itself?”, “can constipation kill you? did it kill Elvis?”, “does saliva have curative properties?” and more.
