As far as living alone in the woods, theres historical material that leads people to believe that the worst punishment that could be given to a person was shunning or forced seclusion.
Getting kicked out of the tribe was a death sentence, a slow starving death. Survival is work, and if you get sick or hurt, you cant work, and if you're alone, you're dead.
Not saying it cant be done, just that its not easy by a long shot.
Good luck, I think everybody thinks of doing it, I did, around 19-20. Wanted to buy a horse and ride to Alaska, do the homestead thing and live off the land. Then I looked at a map, and did the math.
The fact that I couldn't ride a horse kinda helped kill the idea too.
Good luck, go camping, do part of the Appalachian trail, hell do the whole thing, before you move into the woods.
