By and large, all of my clients seemed like nice, normal people, at least via e-mail and on the phone—I never met a single one in person. But in the end, the longer we worked together, the more comfortable the clients tended to become in expressing their more extreme opinions, as if they'd been holding them in. Often, professional decorum (and with it, sometimes basic grammar and spelling) degraded as time went on.
You can survive several weeks without food, but you won't be having a very good time. Food is costly, its supply is fairly easily disrupted, and it's a resource that the government may be much less inclined to deliver to your doorstep when things go wrong. So, with a variety of reasonable scenarios to worry about - anything from natural disasters to economic downturns - it just makes sense to be able to feed yourself even if you can't buy groceries for a while.

Do some research to make sure you are not wasting your time on implausible risks. How likely is it that you would have to face this particular danger, and how much damage can it conceivably cause? For example, do you live in a 100-year flood zone? In the path of tropical storms? In a high-crime neighborhood? Be sure to search around and study publicly available resources; reaching out to local emergency response organizations can be a good plan, too. Try to focus on reputable sources; the science in doomsday movies and on conspiracy websites seldom checks out.
Communication: Radio is still the best way to get emergency info. Unfortunately we’ve had a lot of bad experiences with the $20 to $70 “emergency radios” commonly available on Amazon. Poor reception, awful durability, bloated with unneeded features, etc. So we’re not going to make a recommendation until we’ve done a full product review, but if you’re looking anyway, Kaito and Eton are the two most common brands.

If you going to Cache with Electronics Inside the Container. Consider a 55-Gallon Open Top Drum. Steel Container will Act Like a “Faraday Cage” protecting the Electronics Within. Also consider a Poly-Pheyleneterephtalamide (C14H10N2O2/or simply Kevlar 49) Container Bag to Guard A Against Long Term Corrosion on the Steel 55-Gallon Drum. Kevlar, is Non-Biodegradable and will last for 10,000-years or Longer. But than Again Food Inside Probably WON’T…
“I’m actually responsible, indirectly, for the end of the meetups,” Dr. Shealy tells me inside his Springfield clinic off Chestnut Expressway, and not just because he thinks the earth is more than 6,000 years old. (Andrew: says you can’t trust anyone who believes that.) He sports a red crewneck, navy blue sweatpants, a stretchy metal watch and rectangular glasses. The 85-year-old—he’s more energetic than most people half his age—specializes in holistic medicine; the first thing he asks me is my birthday, and do I know what my astrological sign means. On my way out, he asks if he can hug me, and when I oblige, a toothy grin pulls wide the spritely doctor’s cheeks. “I believe it’s an important part of human contact,” he says. 
Do people buy them? Sure they do. Sales aren't the goal, though. The idea here is to induct people into a lifestyle, because these same people sell things like wilderness survival courses, subscriptions to survival food delivery services, tools and weapons, and vitamins. Prepping is big business, with Yahoo! Finance reporting that as many as 3.7 million Americans identified themselves as "preppers" in 2013, fueling demand for a multi-billion dollar industry.
It's no wonder that all this vivid imagery keeps many preppers preoccupied with civilization-ending events. Some of their worries are based on patently absurd or exaggerated science; some are valid, but rather unlikely to materialize within the span of our lives; and many others boil down to interesting but somewhat idle speculation, devoid of quantifiable risk or historical precedent.

Many preppers are skeptical of couponing, because it still seems to require spending a lot of money.  Using a $1.00 coupon on a purchase of $5.00 means you still have to spend $4.00, right?  Wrong! This is where many preppers get mixed up.  The secret to couponing, what allows some people to be so unbelievably successful with it, is pairing coupons with sales. 

In tropical areas, a survival kit may have mosquito head netting, additional insect repellent, anti-fungal cream, a machete, water purification tablets, foot powder, matches, a flint strike, a compass, a wire saw, a space blanket, medical equipment (gauze pads, elastic gauze bandage, antiseptic creams, anti-malaria tablets, anti-infection tablets, bandages, etc.), salt tablets, a fishing kit, snare wire, extra socks, a candle, a signal mirror, flares, a sewing kit, safety pins, tinder, tape, a whistle, and rations.
