On the 21st: We discussed the World Series champion Chicago Cubs' visit to the White House yesterday. Plus, we learned about research that finds a link between shootings, violence and post-traumatic stress disorder. We also talked with a medical doctor turned journalist about his new book that addresses some of the most common - and quirky - questions people have about the human body.
