Necessary skills to survive for a hypothetically infinite period of time in the wilderness? Related literate and links? I've read Into the Wild and Walden, the first guy failed pretty fucking bad, but Thoreau made a good go of it, although he wasn't entirely alone and ventured into town often. How did they do it? Like how did the Indians do it? They literally had nothing? What would I need to know, and how would I go about knowing, how to provide food, clothing, shelter, and (relative) comfort, in the absolute wild? How would one begin?
