I can hunt, my kids have grown tomatoes, peppers, and onions, I have started a fire without a lighter, but lighters exist and i smoke....I can't think of too many reasons I wouldn't have one, but would have lint and flint.....I can't do it rubbing 2 sticks together, if that's what you mean. I haven't hunted in decades, but I'm sure I can still kill dinner if i had to.....Never been fishing. Scared of water. Childhood trauma.
