Mary Roach’s books are disgusting examinations of the human body—and I love every single one of them. Her latest, Gulp., is an examination of the human digestive system which includes: America’s terrible imported olive oil, the bacteria fighting properties of saliva, the intricacies of smuggling, the possible reason for dragon mythos, and why Elvis died on the toilet. Hilarious and highly informative, Gulp. is a must-read. (Warning: Do NOT read Gulp. right before, during or right after meals, but it’d probably make an interesting bathroom read.)
Like all of Roach's books, Gulp is as much about human beings as it is about human bodies.
