It is obvious that the show is scripted to some degree, but how do you end up in the wilderness with no clothes? Two things that would be a problem for me, group drinking from the same pot, one person getting sick could take out the whole group. No way to sanitize your hands after wiping? As a young teen my cousin and I did this in the Florida wilderness, no we weren't naked, and we called it camping. A pot, a fish line and a .22 caliber rifle for protection. We ate fish, frogs, swamp cabbage etc. No, we didn't stay 21 days, I think the longest was 2 weeks in the summer. I'm 75 years old and would do a 15 day show in Florida if they would let me.
