In the science section at your local bookstore, you'll find plenty of books on everything from the brain, to the climate, to the cosmos.

But how many books will you find that take you on a tour of the digestive tract—from our mouths, to our stomachs, to our intestines? Popular science writer Mary Roach's new book, Gulp, does just that.

Decoding the science of taboo topics like vaginal weight-lifting, amputee bowling leagues, and how much food it takes to burst a human stomach has become the signature style of Roach, who has been described by the Washington Post as "America's funniest science writer."

Mary Roach writes about human bodies in unusual circumstances and does not shy away from things that are gross. Her previous best-selling books include: Stiff: The Curious Lives of Human Cadavers, Spook: Science Tackles the Afterlife, Bonk: The Curious Coupling of Science and Sex, and Packing for Mars: The Curious Science of Life in the Void but today we’ll be discussing Gulp: Adventures on the Alimentary Canal.
