I have to say that I think the show is stupid. I agree with the statement about jumping in the 40 degree water. Hypothermia sets in pretty quickly at that temp. The cold water training I have done was around 50 degrees and it takes your breath away and it is not that easy to swim as you can loose sensation pretty quickly. He seemed to be pretty comfortable in his wet blue jeans. And if he was looking for a way across the river why didn't he just use whatever method the camera-man used, he beat our hero across and kept his camera dry! Coulda used the same boat or bridge or whatever. Also if he needs a way out why not just follow the support crew that is bringing in fresh batteries, unless the camera-man is packing all those along too. In which case the show should be about that guy, because he has the tougher job. It is just not that realistic and seems too staged for my taste.
