Mark Twain once said: "There are lies, Darn (sic) lies, and statistics," meaning the manipulation of data becomes the biggest lie of all.
My Maternal Grandfather (1873-1957). a Free-Methodist minister, used to say; "A man unprepared prays for a short life." Meaning if you're not ready you ain't going to make it.
I live on a 1.5 acre farm on which I raise my own pigs, sheep, chickens, turkeys, ducks, pigeons, bees, grow an orchard of 18 fruit trees and have a greenhouse with a 100x100 foot garden plat. I have a years supply of dried, canned, frozen, and fresh food on hand. I have been involved in butchering my own meat since I was a pre-schooler during the Korean War.
I have 100 gallons of kerosene to light a dozen of those old fashioned hurricane lanterns, extra gas on hand, guns, ammo, and a years worth of hay in the barn. We butchered 2 pigs and a lamb this spring and will butcher two more sheep this fall.
Right now it is hard for me to get around, but I grew up on a farm back in the 1950's and can do some blacksmithing.
My food stores aren't just for me, they are to share with my neighbors.
When disasters strike we do not survive as individuals but as small communities, anyone who doesn't understand that will perish.
