Your run-of-the-mill shoe stank might not pose much of a survival threat, but trench foot certainly will; baking soda is great at absorbing the moisture that might otherwise literally cause your feet to rot off your legs. As for the health of your teeth -- it will be pretty hard to get through your day's rations of homemade jerky and hardtack without some high-quality chompers. And you certainly don't want to rely on that pesky fluoride that will "kill your brain over time" (um, what?).

“Welcome evermore to gods and men is the self-helping man. For him all doors are flung wide: him all tongues greet, all honors crown, all eyes follow with desire. Our love goes out to him and embraces him, because he did not need it. We solicitously and apologetically caress and celebrate him, because he held on his way and scorned our disapprobation.” –Ralph Waldo Emerson

Finelli’s not from around here; an adopted Midwestern politeness hardly masks direct, fast-thinking, faster-talking East Coast roots, although he won’t tell me where he’s from exactly. He’s guarded like that. He won’t say where he went to college, only that he graduated from a prestigious undergraduate program and then got an MBA; nor will he say where he worked after, only that he started a company on the West Coast to manufacture satellite communications receivers before a Japanese competitor threatened to kill him. He will say he knows the moon landing was faked. In 1982, he moved back east from California and began designing computer systems for a Fortune 100 credit card company.
This group consists of people who live in tornado, hurricane, flood, wildfire, earthquake or heavy snowfall-prone areas and want to be prepared for possible emergencies.[34] They invest in material for fortifying structures and tools for rebuilding and constructing temporary shelters. While assuming the long-term continuity of society, some may have invested in a custom-built shelter, food, water, medicine, and enough supplies to get by until contact with the rest of the world resumes following a natural emergency.[31]
_{Jennifer didn’t get into prepping with a hurricane like Maria in mind. Her own personal SHTF moment — the calamity that spurred her to start stockpiling and growing food in the first place — was one that most people can relate to: the sudden closure of the law firm where she’d worked for several years. “We were down to only one income, so I said, ‘I have to really do something to help us get through this,’” Jennifer recalls.}
But now we are a mob. Man does not stand in awe of man, nor is his genius admonished to stay at home, to put itself in communication with the internal ocean, but it goes abroad to beg a cup of water of the urns of other men. We must go alone. I like the silent church before the service begins, better than any preaching. How far off, how cool, how chaste the persons look, begirt each one with a precinct or sanctuary! So let us always sit. Why should we assume the faults of our friend, or wife, or father, or child, because they sit around our hearth, or are said to have the same blood? All men have my blood, and I have all men's. Not for that will I adopt their petulance or folly, even to the extent of being ashamed of it. But your isolation must not be mechanical, but spiritual, that is, must be elevation. At times the whole world seems to be in conspiracy to importune you with emphatic trifles. Friend, client, child, sickness, fear, want, charity, all knock at once at thy closet door, and say,--'Come out unto us.' But keep thy state; come not into their confusion. The power men possess to annoy me, I give them by a weak curiosity. No man can come near me but through my act. "What we love that we have, but by desire we bereave ourselves of the love."

For a time in the 1970s, the terms survivalist and retreater were used interchangeably. While the term retreater eventually fell into disuse, many who subscribed to it saw retreating as the more rational approach to conflict-avoidance and remote "invisibility". Survivalism, on the other hand, tended to take on a more media-sensationalized, combative, "shoot-it-out-with-the-looters" image.[9]

“A lot of the time, what you would have in a bug-out situation is something as simple as a Mylar blanket because the idea is to move from one location to the other, and to do it quickly. But if you do need some sort of shelter, there’s the bivvy bag. That keeps you nice and warm, and you can get into that and use it as shelter, but it’s still small and compact and can fit in a bag.”

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.

Preparedness is a continuous cycle of planning, organizing, training, equipping, exercising, evaluation and improvement activities to ensure effective coordination and the enhancement of capabilities to prevent, protect against, respond to, recover from, and mitigate the effects of natural disasters, acts of terrorism, and other man-made disasters.
Based on this crude but honest assessment of the general public's affinity for the common bicarbonate, you'd be surprised by how much survivalists are into it (#2 on the list of "things for preppers to hoard"). They must expect some pretty serious hankerings for tasty leavened baked goods, or they have extensive phobias about the funkiness of their nuke survival backup plans.
While survivalists accept the long-term viability of Western civilization, they learn principles and techniques needed for surviving life-threatening situations that can occur at any time and place. They prepare for such calamities that could result in physical harm or requiring immediate attention or defense from threats. These disasters could be biotic or abiotic. Survivalists combat disasters by attempting to prevent and mitigate damage caused by these factors.[31][32]
About a month after I left meetup 2.0 at Pizza Hut, former attendee Garland Fitzhugh called to tell me it’s become more of an ‘eat-up’ than a prepper meetup—fair, considering there’s been no local calamity to keep the group on its toes. Allen emails meeting suggestions to a prepper listserv, asking them to focus on prepping situations they can actually influence. He may as well type in Wingdings. A former Navy technician, Allen spent most of the meeting on his phone; his ears only perk up when Andrew: says something about naval intelligence that piques his interest. “I try not to do that too much,” he tells me later. 
There is a downside to ordaining the self with divine authority, though. We humans are fickle creatures, and natures — however sacred — can mislead us. That didn’t bother Emerson. “Speak what you think now in hard words,” Emerson exhorted, “and tomorrow speak what tomorrow thinks in hard words again, though it contradict every thing you said today.” (Memo to Mitt Romney: no more apologies for being “as consistent as human beings can be.” You’re Emersonian!)
FEMA recognizes that widespread cultural change is a long-term process, and while the national statistics on basic preparedness actions have remained largely constant, findings documented in Preparedness in America offer valuable insights for adapting education efforts to increase preparedness. Key findings from the research focus on the public’s behaviors, knowledge, and attitudes related to preparing for a range of hazards.
