Gulp: Adventures on the Alimentary Canal


Mary Roach's curiosity has taken her from a cadaver farm to having sex in an MRI machine. The science writer now brings her deep insight into our deep insides with her latest book, Gulp: Adventures on the Alimentary Canal.

Most people might find that hard to stomach as an athletic competition. But science writer Mary Roach covers the gut and she has a tough constitution as she's shown in her books on human cadavers and laboratory investigations of sex. She needed all the intestinal fortitude she could summon for her latest work, Gulp: Adventures on the Alimentary Canal.

Mary Roach joined us from San Francisco.
