Mary Roach writes humorous popular science about subjects people often find awkward, morbid or technically obscure. Stiff investigates what happens to donated human bodies in medical research, crash testing and other scientific uses, while Gulp follows food through the digestive system and Packing for Mars examines the practical problems of human space travel, including hygiene, food and bodily functions. Bonk turns to the science of sex, and Grunt looks at research designed to help soldiers survive injury and extreme conditions. Roach's books are anecdotal, curious and accessible, using interviews and field visits rather than textbook structure. Her work fits popular science, medical curiosity and humorous non-fiction, especially for readers who like detailed answers to questions that conventional science books often avoid. Read more Less
