Well, if the point of the show were actually about survival, then I suppose these would be good ideas, things I would consider.

However, from what I've seen of the show, it is more about how to screw everyone else (figuratively and literally in many cases) and solve problems that have nothing to do with survival issues. In this context, I think if I were on the show by day three they'd find everyone else in the competition with their throats cut by early morning if the objective is to be "the last man standing".

In contrast, I find the "Survivorman" series particularly entertaining and informative.
