I agree. Many of Bear's tactics leave little room for error. If it isn't executed just right, the results can be devastating, bordering on lethal. Does he demonstrate an expert approach to survival, I would think so. Unfortunately his audience will miss the context of most of his actions and if they follow his example, are more likely than not to experience failure. What he does is extreme, and merely illustrates how bad it can be and what must be done to overcome the worst possible outcomes. That is not a good teaching environment, because the failure for the pupil is so catastrophic as to be impractical.
