Food writer and cookbook author Michael Ruhlman joins us to discuss the origins of grocery stores, how they're designed and where our food comes from. Thomas Ricks, an adviser on national security at the New America Foundation, discusses the intertwining lives of Winston Churchill and George Orwell, and how they stood up against authoritarianism. He examines Churchill’s role in WWII, and Orwell's musings on authority and freedom in works like Animal Farm and 1984. Producers/directors Linda Saffire and Adam Schlesinger join us to discuss their new documentary, “Restless Creature: Wendy Whelan,” along with the film’s subject, former New York City Ballet star Wendy Whelan. The film follows Whelan as she grapples with the physical and emotional realities of being a professional ballet dancer in her mid-40s. Reuters editor-at-large, Harold Evans argues that writers today favor speed over clarity. He shows how editing and revision can help make our writing more precise.
