I enjoy the show but I don't watch it as a "do this and survive" instructional video (just as I would not have expected a sit-com using a home improvement motif to teach me how to renovate a house).
I take everything on tv, in print and online with a grain of salt because I don't really know how many takes, edits, etc. were used in production. Healthy skepticism, critical thinking and being able to recognize what to take and what to leave can be worthwhile lessons when watching "Man vs. Wild."
Gotta say he kills and eats more things and more strange things than I need to see. The guy seems to know how to climb. I often wonder how they get the camera angles and footage they show.
