How are the tools we use to solve personal crises related to national problems? Pulitzer Prize-winning author Jared Diamond says the ways we deal with problems like divorce, the death of a loved one, a serious health problem, or financial troubles, can be used to effectively deal with crises in countries. In his newly-released book, "Upheaval: Turning Points for Nations in Crisis," Diamond examines problems in seven countries, including the United States. How can America succeed at solving problems like political polarization and socio-economic inequality using tools from a crisis therapist? Diamond is also the author of "Guns, Germs, and Steel," along with other books. He’s a professor of geography at UCLA.
