I generally don't watch reality shows, but at the urging of a friend, tuned into this one with my wife, and got hooked. The premise is a man and a woman who don't know previously know each other are injected into a hostile or challenging environment with only a single tool of their choice each and with no clothes and must survive for 21 days. The challenges are (in the approximate order of criticality); get acquainted and establish a cooperative relationship; build a fire; acquire potable water; build a shelter; survive off native plants until you can acquire protein by fishing and hunting; avoid dangerous animals and exposure; be productive with your partner by emphasizing strengths and minimizing weaknesses. Then there is basically realizing that successful survivalism (i.e. surviving", means not making any mistakes (like letting your fire go out or burn down your shelter, or chopping your finger with a machete or drinking bad water and getting dysentery). Further, it helps to be lucky -- if possible avoid bad storms, flash floods, etc. If you like problem-solving; if you like the outdoors and have a respect for real nature; if you are fascinated by observing human nature under stress, you will probably enjoy this show. I've watched five programs to date, and quickly noticed the people selected are all "well-nourished" as coroners used to say -- not fat, but not thin. Every participant is faced with the huge challenge of trying to get enough calories to get by, and we quickly learn what a huge disadvantage most modern humans are at when they do not have tools or their culture to rely upon. The average weight loss among the ten people so far be roughly 30 lbs in 21 days, and it's easy to see the toll of stress and anxiety on the participants.
