When I got into bed that night, I noticed I was feeling a little off. Though I’d technically consumed enough calories, my stomach was still gnawing with hunger, and when I woke up the next morning, I felt energyless. I phoned Dr. Lisa Young, a New York–based nutritionist and adjunct professor at NYU, with a question: Is it really possible to live off freeze-dried food?

Robert A. Johnson sees his peers’ talk of fleeing as the symptom of a deeper crisis. At fifty-nine, Johnson has tousled silver hair and a soft-spoken, avuncular composure. He earned degrees in electrical engineering and economics at M.I.T., got a Ph.D. in economics at Princeton, and worked on Capitol Hill, before entering finance. He became a managing director at the hedge fund Soros Fund Management. In 2009, after the onset of the financial crisis, he was named head of a think tank, the Institute for New Economic Thinking.

These individuals study End Times prophecy and believe that one of various scenarios might occur in their lifetime. While some Christians (and even people of other religions) believe that the Rapture will follow a period of Tribulation, others believe that the Rapture is imminent and will precede the Tribulation ("Pre-Trib Rapture[41] "). There is a wide range of beliefs and attitudes in this group. They run the gamut from pacifist to armed camp, and from having no food stockpiles (leaving their sustenance up to God's providence) to storing decades' worth of food.
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.
People who want to learn are worth something, because they WILL learn if taught. They’re hungry for knowledge, and they don’t allow their ego to get in the way of their training. If you know more than they do on a subject, they’ll want you to show them what they don’t know, regardless of who you are. You won’t hear their arrogance drowning out the mission; instead, you’ll see someone who is humble and willing to work. Even someone with no skills, who is eager to put in the work and learn is better than someone with a skill who refuses to learn anything new. The flip side of that is someone who brings better skills than you have to the table in a certain area. If they’re willing to teach you, be willing to learn yourself as well.

Every year in the US about 150 people die while out and about in national parks, more than 1,000 die in hunting-related incidents and thousands of backcountry enthusiasts get in deep trouble and require a Search and Rescue team to save them; with dozens of those folks dying while awaiting rescue. Most fatalities are the result of poor preparation. Bad weather descends and people get lost. They wander without water or shelter, often injuring themselves in the process. If they survive they often suffer frostbite, hypothermia, dehydration, trench foot or some combination of them all.

But in 1961 John F. Kennedy encouraged “every citizen” to help build fallout shelters, saying, in a televised address, “I know you would not want to do less.” In 1976, tapping into fear of inflation and the Arab oil embargo, a far-right publisher named Kurt Saxon launched The Survivor, an influential newsletter that celebrated forgotten pioneer skills. (Saxon claimed to have coined the term “survivalist.”) The growing literature on decline and self-protection included “How to Prosper During the Coming Bad Years,” a 1979 best-seller, which advised collecting gold in the form of South African Krugerrands. The “doom boom,” as it became known, expanded under Ronald Reagan. The sociologist Richard G. Mitchell, Jr., a professor emeritus at Oregon State University, who spent twelve years studying survivalism, said, “During the Reagan era, we heard, for the first time in my life, and I’m seventy-four years old, from the highest authorities in the land that government has failed you, the collective institutional ways of solving problems and understanding society are no good. People said, ‘O.K., it’s flawed. What do I do now?’ ”
Huffman, who lives in San Francisco, has large blue eyes, thick, sandy hair, and an air of restless curiosity; at the University of Virginia, he was a competitive ballroom dancer, who hacked his roommate’s Web site as a prank. He is less focussed on a specific threat—a quake on the San Andreas, a pandemic, a dirty bomb—than he is on the aftermath, “the temporary collapse of our government and structures,” as he puts it. “I own a couple of motorcycles. I have a bunch of guns and ammo. Food. I figure that, with that, I can hole up in my house for some amount of time.”

Religion, however, has everything to do with survivalism—there are things about your faith that affect the way you live, Fletch says, offering me an example. “Today, a great deal [on the menu] was the special you had,” he says. “Every one of the specials had pork in it. Well, depending on your belief system and where you’re coming from, Dan, you could’ve made several decisions about me.” He’s right; I could’ve thought he assumed the breakfast was on me, so he ordered the most expensive dish on the menu. And those assumptions, he says, can break up a group. “If 99 percent of the people in your group don’t eat pork, and you bring in some person eating a ham sandwich next to you, that’s going to cause some conflict.” 

A number of popular movies and television shows[definition needed], such as the National Geographic Channel's Doomsday Preppers, have also emerged recently[when?] to capitalize on what Los Angeles Times' entertainment contributor Mary McNamara dubbed "today's zeitgeist of fear of a world-changing event."[28] Additionally, doomsday ideas disseminated mostly online in relation to the 2012 phenomenon surrounding misunderstandings about the Mayan calendar fueled the activities of some survivalists during the run-up to the phenomenon's purported December 2012 date of the world's demise.
Yishan Wong, an early Facebook employee, was the C.E.O. of Reddit from 2012 to 2014. He, too, had eye surgery for survival purposes, eliminating his dependence, as he put it, “on a nonsustainable external aid for perfect vision.” In an e-mail, Wong told me, “Most people just assume improbable events don’t happen, but technical people tend to view risk very mathematically.” He continued, “The tech preppers do not necessarily think a collapse is likely. They consider it a remote event, but one with a very severe downside, so, given how much money they have, spending a fraction of their net worth to hedge against this . . . is a logical thing to do.”
If the fire is around you and you can’t escape, you don’t have many options, says Shane Hobel of the Mountain Scout Survival School. If there’s a pool or a pond nearby, jump in and try to wait it out there. Otherwise, if you have time, dig a trench that’s two to three feet deep and long enough for you to lie in. Soak a blanket in water, wrap it around yourself, and lie down in the trench. It’s risky, but at least you’ll have a chance.
