How do you define courage? After speaking with Jack Fairweather, author of "The Volunteer: One Man, An Underground Army & the Secret Mission to Destroy Auschwitz, I am convinced that one of the ultimate examples is a 39 year-old Polish underground operative named Witold Pilecki. Pilecki VOLUNTEERED to be a prisoner at the infamous Auschwitz death camp beginning in 1940. The goal was to help the Allies get first-hand information on the camp. It is a study in grace, sacrifice, empathy and courage, among other positives human qualities. It's an episode you won't want to miss and a book you will want to read.
