Bear Grylls and Tim Taylor (Home Improvement show) are both good examples of what not to do. Tim Taylor shows how to have body parts removed or damaged in a most unpleasant way. Bear does things that would likely kill or seriously harm you if you did not have the support network he has. Just because he is the only person you see on the show doesn’t mean he’s out in the wild alone. Unlike Les Shroud (Les’s show is actually about him being alone and having to cope.) I would imagine there is a lot of Bear’s show that doesn’t get aired because it’s him sitting and recovering or taking a time out (with a cappuccino in his hand and a blanket around him) having his crew wait on him because he did something stupid.
