long term storage/survival foods

we "store what you eat, eat what you store" and "rotate,rotate,rotate", I don't think anyone can store enough(of anything) to last the rest of their lives(here in the UK we prep for a maximum of 12-18 months after that its growing what we can, foraging and snaring..the old hunter/gatherer lifestyle) at some point all your stores will run out, by that time the "die off" of the sheeple and the unprepared will have taken their course and the competition will be low or even non existent.
