I think the biggest danger from wading in the ocean at night, especially barefoot, would be falling on coral and suffering a pretty big gash. sharks and other animals are a distant (but not impossible) second. i learned to be very methodical in a survival situation, and avoid unnecessary risks. suffering a major injury in a survival situation could truly be the end of the road. (this is what makes bear's show seem so counterproductive to me)

i do agree with benjammin and hikin_jim that Les does put himself in situations we could all wind up in, and he does come out alive with less gear than most of have in our pockets right now. i guess there is the entertainment aspect of the show so his mistakes are kept in the final footage. i guess i'll just try not to make the same mistakes he does.
