As a retired veteran, a graduate of several survival schools, someone who teaches it for a job (occasionally), and a scoutmaster who teaches this stuff to the kids, I have to tell them constantly to not take what they see on TV seriously. They do look at these shows as if they impart knowledge. The kids, and their parents in many cases, need to be told how bad some of the techniques are that they have seen. In the best case, they are not seeing all of the components of a skill that is demonstrated. These shows do not teach survival techniques. Emulating any of them will likely get you in trouble in a real life situation.
