" Be prepared" is a double edged sword. Yes, have food sources, water, a plan etc. but also be prepared to watch your loved ones suffer and die, one by one; mainly children , elderly, and the sick.
Living like "the 1800's" is NOT the same as a total collapse of society. You can't boy scout or country boy your way out of a hoard of desperate starving worst of the worst humans. You may last much longer than 95% of the people but your day will come sooner or later.
