• Extreme survival expert Ken Kamler • Discussing what happened to Fran Crippen, a U.S. competitive swimmer who died in a race in the United Arab Emirates over the weekend. Crippen was swimming in very extreme conditions – it was over 100 degrees outside and the water temperature was around 87 degrees, which is the average temperature of hot tub water.
