@alxd The article reminded me of the guy that went to live by himself somewhere in Alaska. They found is body in an abandoned bus. I think there is a book and a movie about it. An article suggested that his last meal poisoned him. The greens were edible in other areas but had too many toxins(?) where he was for the way he had to rely on them. A local community might have taught him to avoid self-poisoning with local plants.
