I did watch the first 2 episodes a few weeks ago based on this thread, and had actually forgotten about the show already until I saw this thread pop back up. They weren't naked, aren't they supposed to be naked and alone or something?
People sticking bones in their noses, contestants not knowing much about their surroundings, people with apparent health issues, etc, and not being naked caused me to loose interest pretty quickly.
I literally only watched one episode of 'Naked and Afraid' just because a teacher of mine was on it. He called it "Naked and Bored"
