This group stresses being able to stay alive for indefinite periods in life-threatening wilderness scenarios, including plane crashes, shipwrecks, and being lost in the woods. Concerns are: thirst, hunger, climate, terrain, health, stress, and fear.[31] The rule of 3 is often emphasized as common practice for wilderness survival. The rule states that a human can survive: 3 minutes without air, 3 hours without shelter, 3 days without water, 3 weeks without food. [33]
Business for Hardened Structures, an engineering firm based in Virginia Beach, is up roughly 40% since 2005, co-owner Brian Camden says. Some of his clients buy gold and silver and other precious metals as a hedge against a possible collapse of the currency, and they want to be able to protect it and their families, he says. So his company designs ways to build underground bunkers, strengthen walls and improve security systems on homes.
I'm not quite crazy enough to say that epinephrine will help you survive the inevitable zombie apocalypse (you can go here for that). I'm just suggesting in a roundabout way that if you happened to be in a situation where something was trying to eat you, the increased heart rate and blood flow to your muscles brought on by a well-timed dose might just save your life.
Last spring, as the Presidential campaign exposed increasingly toxic divisions in America, Antonio García Martínez, a forty-year-old former Facebook product manager living in San Francisco, bought five wooded acres on an island in the Pacific Northwest and brought in generators, solar panels, and thousands of rounds of ammunition. “When society loses a healthy founding myth, it descends into chaos,” he told me. The author of “Chaos Monkeys,” an acerbic Silicon Valley memoir, García Martínez wanted a refuge that would be far from cities but not entirely isolated. “All these dudes think that one guy alone could somehow withstand the roving mob,” he said. “No, you’re going to need to form a local militia. You just need so many things to actually ride out the apocalypse.” Once he started telling peers in the Bay Area about his “little island project,” they came “out of the woodwork” to describe their own preparations, he said. “I think people who are particularly attuned to the levers by which society actually works understand that we are skating on really thin cultural ice right now.”
When I visited Johnson, not long ago, at his office on Park Avenue South, he described himself as an accidental student of civic anxiety. He grew up outside Detroit, in Grosse Pointe Park, the son of a doctor, and he watched his father’s generation experience the fracturing of Detroit. “What I’m seeing now in New York City is sort of like old music coming back,” he said. “These are friends of mine. I used to live in Belle Haven, in Greenwich, Connecticut. Louis Bacon, Paul Tudor Jones, and Ray Dalio”—hedge-fund managers—“were all within fifty yards of me. From my own career, I would just talk to people. More and more were saying, ‘You’ve got to have a private plane. You have to assure that the pilot’s family will be taken care of, too. They have to be on the plane.’ ”
Freeze-dried food is nothing new. As early as the 13th century, the ancient Quechua and Aymara people of Bolivia and Peru pioneered a form of the process by exposing potatoes to the freezing temperatures of the Andes overnight, then drying them in the sun. In 1937, Nestlé used industrial technology to create the world’s first freeze-dried coffee, and in the 60s and 70s, the US military shipped freeze-dried food rations to the troops in Vietnam.
I’m not going to try to candy coat this one. If you need this product, you’re in the middle of a terrorist attack or an act of war using a chemical warfare agent (CWA). The people around you will be dying. You’re going to die, too, if you breathe in these chemicals. But if you only have skin contact with these lethal substances, and you have a decontaminant at hand – you can neutralize them. Let that sink in for a moment. If you only come into contact with a chemical weapon on your skin, there is a product that will counteract most toxins. Now, this isn’t exactly a new product. In fact the company has been making this product for many years, and a friend of mine has successfully used it in “live agent” military training. The part that’s new is that this product is now available to civilians. RSDL is the only decontaminant cleared by the U.S. Food and Drug Administration to remove or neutralize chemical warfare agents such as tabun, sarin, soman, cyclohexyl sarin, VR, VX, mustard gas and T-2 toxin. It’s a simple little packet of lotion-like neutralizer. Each kit comes with instructions and a training product, so you can get a feel for it through realistic practice. It also comes with a packet of decontaminant for one person, which removes the chemical agent from the skin in a single step.
And, of course, people aren't going to stop wanting to get drunk just because they can't pop over to the corner bodega for a six pack whenever the urge strikes. Portability and long shelf-life make liquor of all types a valuable trade good -- people will kill to get a taste of the delicious bottom-shelf leftovers from your local dive bar when their only other option is the equivalent of prison wine.
An American hedge-fund manager in his forties—tall, tanned, athletic—recently bought two houses in New Zealand and acquired local residency. He agreed to tell me about his thinking, if I would not publish his name. Brought up on the East Coast, he said, over coffee, that he expects America to face at least a decade of political turmoil, including racial tension, polarization, and a rapidly aging population. “The country has turned into the New York area, the California area, and then everyone else is wildly different in the middle,” he said. He worries that the economy will suffer if Washington scrambles to fund Social Security and Medicare for people who need it. “Do you default on that obligation? Or do you print more money to give to them? What does that do to the value of the dollar? It’s not a next-year problem, but it’s not fifty years away, either.”

Jack Matthews, an American who is the chairman of MediaWorks, a large New Zealand broadcaster, told me, “I think, in the back of people’s minds, frankly, is that, if the world really goes to shit, New Zealand is a First World country, completely self-sufficient, if necessary—energy, water, food. Life would deteriorate, but it would not collapse.” As someone who views American politics from a distance, he said, “The difference between New Zealand and the U.S., to a large extent, is that people who disagree with each other can still talk to each other about it here. It’s a tiny little place, and there’s no anonymity. People have to actually have a degree of civility.”

Those impulses are not as contradictory as they seem. Technology rewards the ability to imagine wildly different futures, Roy Bahat, the head of Bloomberg Beta, a San Francisco-based venture-capital firm, told me. “When you do that, it’s pretty common that you take things ad infinitum, and that leads you to utopias and dystopias,” he said. It can inspire radical optimism—such as the cryonics movement, which calls for freezing bodies at death in the hope that science will one day revive them—or bleak scenarios. Tim Chang, the venture capitalist who keeps his bags packed, told me, “My current state of mind is oscillating between optimism and sheer terror.”
Monetary disaster investors believe the Federal Reserve system is fundamentally flawed. Newsletters suggest hard assets of gold and silver bullion, coins, and other precious-metal-oriented investments such as mining shares. Survivalists prepare for paper money to become worthless through hyperinflation. As of late 2009 this is a popular scenario.[37][38][39][40] Many will stockpile bullion in preparation for a market crash that would destroy the value of global currencies.
Here is a mental exercise: Put yourself in the mind set of Mr. Joe Sixpack, Suburbanite. (Visualize him in or near a big city near where you live.) He is unprepared. He has less than one week’s food on hand, he has a 12 gauge pump action shotgun that he hasn’t fired in years, and just half a tank of gas in his minivan and maybe a gallon or two in a can that he keeps on hand for his lawn mower. Then TEOTWAWKI hits. The power grid is down, his job is history, the toilet doesn’t flush, and water no longer magically comes cascading from the tap. There are riots beginning in his city. The local service stations have run out of gas. The banks have closed. Now he is suddenly desperate. Where will he go? What will he do?
By his own estimate, Pense says there are a few thousand people in the Springfield area who have listened and who are ready. The preppers. Most don’t like to be called preppers because of the connotation that they’re crazy; Chicken Little wasn’t well-received by his people, either. Most don’t even like to talk about it, but a few of them do. So for three months toward the end of 2017, I sought out the doomsday survivalists to find out: Is it really crazy to live like the sky is falling?
Johnson wishes that the wealthy would adopt a greater “spirit of stewardship,” an openness to policy change that could include, for instance, a more aggressive tax on inheritance. “Twenty-five hedge-fund managers make more money than all of the kindergarten teachers in America combined,” he said. “Being one of those twenty-five doesn’t feel good. I think they’ve developed a heightened sensitivity.” The gap is widening further. In December, the National Bureau of Economic Research published a new analysis, by the economists Thomas Piketty, Emmanuel Saez, and Gabriel Zucman, which found that half of American adults have been “completely shut off from economic growth since the 1970s.” Approximately a hundred and seventeen million people earn, on average, the same income that they did in 1980, while the typical income for the top one per cent has nearly tripled. That gap is comparable to the gap between average incomes in the U.S. and the Democratic Republic of Congo, the authors wrote.
David Sarti, a YouTube "firearms instructor" and self-taught survivalist, is prepared for an electrical grid failure; Kellene Bishop of Utah has stocked only the finest gourmet survival foods in preparation for financial collapse; Kathy Harrison, "the Doris Day of Doom", has prepared her local community for a New Madrid earthquake; Dennis Evers brings the family together to survive global chaos caused by hyperinflation.
SOG made their shovel practical survival gear by cutting back its length to a manageable 18 ¼” and its weight to an equally manageable 24 ½ ounces. It folds up to a mere 1 foot long and can be easily strapped to the exterior of any decent sized backpack. The SOG shovel also boasts a row of thick rugged teeth along the side for hacking and cutting underbrush or harvesting wood for your fire. The blade can also be rotated and used as a pick or a hoe to do more precise clearing. All in all this is a piece of survival gear you won’t want to do without.
What programs like Doomsday Preppers have accomplished, or at least contributed to, is turning sometimes well-informed, sometimes totally unwarranted paranoia into a booming prepper-industrial complex. Each year, swap meets pack hundreds of convention centers and fairgrounds across the nation—they’re like camping shows with a dose of military surplus and hands-on instructional sessions. The September 2017 Kansas City Survival Expo & Gun Show, for instance, had tips on seed saving, “Overcoming 900 Health Diseases” and “A Devastating Street Self-Defense System.” The latter was taught by Norman Cantwell, who inspired Patrick Swayze’s character in Roadhouse. You get the feeling that he and Steven Seagal would be friends. 
Don’t buy in bulk unless you plan to repackage your food into Mylar bags, vacuum-sealed bags, or canning jars. Once you open a large container of food—such as flour or coffee—the flavor and texture start to degrade. Storage containers provide an airtight seal that keeps rodents and pests out. Proper storage also keeps food nutritionally stable and extends the shelf life.
Interest in the movement picked up during the Clinton administration due in part to the debate surrounding the Federal Assault Weapons Ban and the ban's subsequent passage in 1994. The interest peaked again in 1999 triggered by fears of the Y2K computer bug. Before extensive efforts were made to rewrite computer programming code to mitigate the effects, some writers such as Gary North, Ed Yourdon, James Howard Kunstler,[18] and investments' advisor Ed Yardeni anticipated widespread power outages, food and gasoline shortages, and other emergencies. North and others raised the alarm because they thought Y2K code fixes were not being made quickly enough. While a range of authors responded to this wave of concern, two of the most survival-focused texts to emerge were Boston on Y2K (1998) by Kenneth W. Royce, and Mike Oehler's The Hippy Survival Guide to Y2K. Oehler is an underground living advocate, who also authored The $50 and Up Underground House Book,[19] which has long been popular in survivalist circles.
One major upside of freeze-dried food is its convenience. Since all its water content has been removed—via a process that involves exposing food to subzero temperatures, while removing the resulting water vapor with a vacuum—it’s easier than canned goods to transport on the fly. To “cook” Wise Company’s six-grain Apple Cinnamon Cereal, you just boil three and a half cups of water, dump in the powdery contents of the bag (minus the oxygen absorber), and cover the pot for 12 to 15 minutes.
Tim Chang, a forty-four-year-old managing director at Mayfield Fund, a venture-capital firm, told me, “There’s a bunch of us in the Valley. We meet up and have these financial-hacking dinners and talk about backup plans people are doing. It runs the gamut from a lot of people stocking up on Bitcoin and cryptocurrency, to figuring out how to get second passports if they need it, to having vacation homes in other countries that could be escape havens.” He said, “I’ll be candid: I’m stockpiling now on real estate to generate passive income but also to have havens to go to.” He and his wife, who is in technology, keep a set of bags packed for themselves and their four-year-old daughter. He told me, “I kind of have this terror scenario: ‘Oh, my God, if there is a civil war or a giant earthquake that cleaves off part of California, we want to be ready.’ ”

It turns out that when you're down to your last moldy hunk of bread and giardia-laced mud puddle, letting it all melt away in a cloud of smoke for a few precious moments can mean the difference between giving up and giving the rat (eating) race another go. If history has anything to say, it's more common than you think for people to happily give up MREs and gunlord harems in return for hastening their ends with carcinogens wrapped up in tidy paper packages. In traumatic situations like war, cancer sticks are often valued more highly than food. Even in the current (more or less) pre-apocalyptic global economy, cigarettes are one of the stable forms of currency.

Firearms instructor and survivalist Colonel Jeff Cooper wrote on hardening retreats against small arms fire. In an article titled "Notes on Tactical Residential Architecture" in Issue #30 of P.S. Letter (April, 1982), Cooper suggested using the "Vauban Principle", whereby projecting bastion corners would prevent miscreants from being able to approach a retreat's exterior walls in any blind spots. Corners with this simplified implementation of a Vauban Star are now called "Cooper Corners" by James Wesley Rawles, in honor of Jeff Cooper.[7] Depending on the size of the group needing shelter, design elements of traditional European castle architecture, as well as Chinese Fujian Tulou and Mexican walled courtyard houses have been suggested for survival retreats.

Survivalists maintain their group identity by using specialized terminology not generally understood outside their circles. They often use military acronyms such as OPSEC and SOP, as well as terminology common among adherents to gun culture or the peak oil scenario. They also use terms that are unique to their own survivalist groups; common acronyms include:

There are two scenarios everyone—prepper or not—should count on: losing power and being stranded in your car. I’m a big believer in backup power. I keep an emergency power supply plugged into an outlet in my apartment; it has a trickle charger so I can forget about it until my block goes dark. In my car, I keep extra blankets, a LifeStraw portable water filter, lighters, and Millennium energy bars. It’s not the Four Seasons, but at least my family will be able to survive 48 hours in our Honda Pilot. One thing to consider: You need to be with your gear when a disaster strikes. When Sandy hit in 2012, our whole family was in Connecticut while all my gear was in Manhattan. My wife had a good laugh. These days, my everyday bag is a waterproof Showers Pass backpack where I stash a small set of screwdrivers, multitool, glass breaker, three flashlights that use the same type of batteries, and a spool of Kevlar thread, all sorted in plastic bags. There’s a spoon and fork in there, too, because if I have to eat an MRE for dinner, I might as well look civilized while I do it.—Wylie Dufresne, Michelin-starred Chef, Owner Of Du’s Donuts, Prepper
