Science writer Mary Roach is fascinated by the human body, especially, she says, the "gooey bits and pieces of us that are performing miracles on a daily basis. Roach has done deep dives on human cadavers, the digestive system and the science of sex. Now, in Replaceable You, she chronicles both the history of body part replacement (including prosthetic noses that date back to the 1500s), and more recent medical breakthroughs in regenerative medicine. Roach spoke with Terry Gross. 

This month marks Terry's 50th anniversary as host of Fresh Air. To commemorate the milestone, Sam Fragoso interviewed Terry for his podcast Talk Easy. In this excerpt, Gross shares her life motto and tells a story about writing song lyrics in high school.
