Beyond Human Limits (2006)

Three adventurous scientists risk their lives exploring the limits of their bodies. Will they survive their own experiments? The human body is a wonderfully complex machine. Confronted with extreme conditions such as hypoxia, cold, and isolation, it triggers off strange and primitive survival mechanisms that modern science is only beginning to understand. Based on true stories, with re-enactments and 3-D medical imagery, Beyond Human Limits recounts the adventures of three scientists who had risked their lives to explore the limits of their bodies.
