I watch the show and always learn something from each episode. Sometimes it is something to do, sometimes is something not to do. The one thing that I find odd is when something goes wrong with a person who is "very experienced" at doing whatever they are doing (sailing, mountain climbing, etc). They usually seem unprepared for someone with their experience level. But it does get me thinking about what I would do differently, both at the start of the trip (long before the emergency) and once the emergency begins.
