This clip is from a show called Man vs Wild.
Bear Grylls is surviving in the French Alps with only a water bottle, flint, and knife. In this excerpt he jumps into a frozen lake and shows how to deal with it. Hopefully this wonâ€™t ever come in handy.
This actually happened to Andrew Skurka during his 7700 mile hike across North America. Stuck in the middle of nowhere with no change of clothes, Skurka stripped down and ran to keep his body heat up.

This is very much like Les Stroud’s Canadian reality TV show Survivorman.
