On Friday, Scott Kelly embarks on a one-year trip to the International Space Station to study the physiological effects of long-term spaceflight. Crucial to the mission is his twin brother, former astronaut Mark Kelly, who will be acting as a sort of controlled variable here on Earth. Today on Word of Mouth, we speak with Mark about being the sibling who stays home. Later in the show, we celebrate the culture of the Jewish deli, and ask whether restaurants based on thick meaty sandwiches and 'schmaltz' can survive in the age of the kale smoothie.
