everyone is a prepper in one way or another, I haven't had a flat tire in years, but I still carry a jack and spare tire in my cars. You probably haven't had a house fire ever or at least not recently but I'm sure you have smoke/fire alarms and an extinguisher in the house. I'm sure if you heat with wood or pellets you try to have the years supply in before the snow flies. being a mechanic I have a set of tools in both cars just in case, and carry a leatherman in my pocket wherever I go. Being a mechanic who works for a regional airline I keep an overnight bag packed in the car and take it on any trip I get sent, even those "short easy" jobs.
I've seen enough of those prepper shows to think they are more fluff than useful, I really wonder how all those urban dwellers will do in their cold dark house with all it's large ground floor windows, no wood stove to heat or cook on... good luck with that! If society breaks down to that point you will need a concrete bunker, just ask all those poor people barricaded into their homes in NY and NJ after sandy, wolf packs of teens roaming around robbing homes and stores, and the people terrified inside. your average home is so weak it is a joke, and if they really want to get what you have fire always works...
an EMP bomb (which more than one country is working on) is a "poor mans nuke", would take out pretty much everything, the whole electric grid, gas mains, and anything else with a computer in it. the only cars and trucks running would be ones with carburetors and non computerized diesels, of course at any moment the sun could spit out an electromagnetic pulse that would do the same thing, it has happened at least once, the last one blasted Canada but since it happened back when the only electronics around were the telegraph wires, it sent so many pulses racing through the wires they overheated sagged, some broke and arced into the ground setting off prairie fires.
Not many of us will survive if that happens today, even your hardest core prepper or off-the-grid fanatic is way too dependent on electricity and gasoline to survive. I think people like the old order Amish could have a better shot at it, they already live without most of the technology from the last century. Just imagine the most powerful thing around being a team of oxen, the fastest being a horse, and no stores to shop at. cutting all the wood to heat the house with an axe and two man saw ( and where are you going to get more of them?) no chainsaw. farming with no tractors, clearing land with no bulldozers or backhoes, tilling, planting, weeding, harvesting, with no tractor, washing clothes by hand, making your own soap, candles, clothes, learning how to cook with just a wood stove (who will make them) or fireplace. all that stuff that is fun to visit at historic places, not so much fun to live with.
say what you want about Mormons, but they are better prepared for real life than anyone else
