The woman called “America’s funniest science writer” ventures down the hatch on a one-of-a-kind tour of our insides. It turns out the alimentary canal is classic Mary Roach terrain: The questions inspired by our insides are as taboo, in their way, as the cadavers in her bestseller Stiff and as surreal as the universe of zero gravity explored in Packing for Mars. In her latest book, Gulp, Roach introduces the scientists who tackle the questions no one else thinks (or has the courage) to ask—Why is crunchy food so appealing? Why doesn’t the stomach digest itself? Can constipation kill you? Did it kill Elvis?—all with her unique approach, making Gulp as much about human beings as it is about human bodies.
