: Does it deaden your sex life to participate in a sex study? That’s just one of the questions host Kelly Corrigan tosses out to best-selling author Mary Roach in a quest to find out whether it’s really better to know more about everything. No topic is off limits as Roach and Corrigan roam through sex and death, oysters and martinis, and meeting the “Other” with an open heart. Along the way, they discover just a few of the ways human life can have meaning.

Mary Roach is an award-winning science writer who has produced nothing but bestsellers since she hit the scene with “Stiff” in 2003.
