I watched this on the Discovery channel last night. Wow! Two naked strangers have to survive for 21 days and make it to an extraction point to win the challenge. They can have one personal item, a knife or machete seemed to be popular. They are given a personal journal a video camera and crude shoulder satchel. They are naked so modesty is provided by blurring. Extreme primitive survival? or two naked people suffering...Yep Discovery, the same people who brought us Doomsday preppers. Go figure.
