Survival TV.

Lately I have been watching some of the stuff on the discovery channel http://dsc.discovery.com and I have found the show Man vs Wild to be really interesting, the idea of the show is to demonstrate how to survive in some very hostile environments if as a tourist you somehow lost the use of your transport and had only items such as the clothes on your back and a knife. Bear Grylls http://www.beargrylls.com/ the shows host gets dropped into some difficult regions of the world and he has to make use of the landscape and within a 5 day minimum he has to find civilisation making his way down from the top of the Rockies or the Swiss alps, all the time demonstrating how to survive a 70 foot jump into a large river or if while walking on thin ice and falling through how to get out and how to get yourself warm again. Also how to find food and how to catch food to live off, such as fish. There are also other interesting shows such as "I shouldn't be alive". Documentary type show which shows how some people have survived amazing ordeals.
