On today's episode, we're talking about the third man factor. Some people, when faced with life-threatening situations, sense the presence of another person. This presence offers words of encouragement, support, and guidance, and has led some people to overcome seemingly impossible odds. 

We share stories of Ernest Shackleton's Antarctic expedition, Ron DiFrancesco's escape from the World Trade Center, Jerry Linenger's experience on the Muir space station, and James Sevigny's miraculous avalanche survival.
