If you own a house, especially in a region prone to earthquakes or tropical storms, you should probably have a sledgehammer, a chainsaw (with a charged battery or some fuel at hand), bolt cutters, and a pry bar. These heavy tools are essential for clearing debris and getting to whatever's underneath. Keep them far from your other supplies: if your primary stash gets pinned under other junk, you can use the tools to get it out. Don't store pry bars and similar equipment in plain sight; robbers often use found tools to force patio doors, to pop safes, or worse.

3. The water will slowly filter through the charcoal and drip out of the cap. Put a bandanna or another cloth over the hole to filter out any bits of charcoal. (If you’re experiencing intestinal distress—and you very well might be, since your body goes into different kinds of shock in these situations—eat a little bit of the charcoal. It’ll help bind you back up.)

The format is fairly standard for a "reality documentary". It does go with the more extreme folks rather than the more common folks who are just putting some things aside for rougher times. But that's OK, in most of the cases. I found many of the people to be pretty ingenious in how they've approached what they perceive to be The End Of The World As We Know It. Maybe they're right, maybe they're wrong. A few might even be slightly over the top (well, there are a few that I think put a step ladder on the top and went from there...) But they have what they consider to be valid reasons for doing what they're doing, so who am I to argue?

If there was anything my freeze-dried food experiment taught me, it was how lucky I was to be able to walk down the street and buy a sandwich whenever I wanted to—but also how far I was from being self-reliant in the more quotidian sense. If freeze-dried meals are becoming increasingly popular in America, then maybe it’s because many of us realize that if something really bad happened, we wouldn’t know the first thing about surviving for a week on the ingredients lying around in our pantry. But as we continue to be bombarded by headlines foreshadowing epic floods, economic collapse, and nuclear escalation, there’s nothing wrong with finding a little peace of mind in a bag of dehydrated Chicken A La King.
Since then, the direction has been inauspicious. In January, 2016, after increasing military tensions between Russia and NATO, and the Earth’s warmest year on record, the Bulletin set the clock at three minutes to midnight, the same level it held at the height of the Cold War. In November, after Trump’s election, the panel convened once more to conduct its annual confidential discussion. If it chooses to move the clock forward by one minute, that will signal a level of alarm not witnessed since 1953, after America’s first test of the hydrogen bomb. (The result will be released January 26th.)
If you are trekking through the Yukon or trying to cross the Darien gap, you may find it necessary to wait weeks for help to reach you in a survival situation; but if you are just heading off to your local state park, emergency rescuers could probably reach you in a matter of hours. You’ll want to factor this consideration into your kit-building decisions. If you can expect to wait long periods before help will arrive, you’ll need more supplies than if you are heading out to an easily accessed area. Nevertheless, it is always wise to have the supplies to last longer than you think you’ll need them.
There are those who are born into familial wealth or who display supernatural business acumen. Then there is the rest of us, perhaps having robust and satisfying careers, but ultimately tiptoeing the line between middle-class prosperity and crushing poverty. It may be a matter of our employer going out of business, it may be a shift in the job market, an illness, or a legal dispute - but in all likelihood, it would not take much to send us over the edge. I have friends who lived paycheck-to-paycheck on cozy Silicon Valley salaries of $100k+ a year, only to lose their cars and homes in the midst of the 2007 financial crisis - having found out the hard way that unemployment benefits in the San Francisco Bay Area max out at $450 a week.
We keep getting away with all that goofiness, and that only serves to make us more certain that our own transgressions carry no serious risks. But government statistics tell a strikingly different tale: in the US alone, unintentional injuries result in 40 million ER visits and 100,000 deaths every year. Heck, accidental injury is the leading cause of death for people between the ages of 1 and 45 - far ahead of cancer, heart disease, gun violence, and other pop culture bogeymen. And the injuries themselves are very prosaic, too: all you see are falls, cuts, burns, vehicular collisions, poisonings, and so forth. The "idiots" we sometimes watch on Youtube are us. They just happen to have been caught on camera on the day their luck ran out, perhaps aided by downing a couple of beers.
Experts worry most about the grid’s nervous system: 2,000 extra-high voltage transformers. They’re 200- and 300-ton behemoths, individually engineered to meet specific power demands, and on average, they’re 40 years old. Notwithstanding the fact that 85 percent of transformers are imported, the U.S. Department of Energy says it takes between 5 and 16 months to replace a single one. According to the U.S. Federal Energy Regulatory Committee, an attack that destroyed nine of the 2,000 transformers would “cause a protracted nationwide blackout.” There’s no national cache of spare transformers. 
Alas, most of the popular diets make this task awfully hard: they force their followers to abandon a lifetime of dietary habits, taste preferences, and eating schedules - and stuff themselves full of kale, turnips, quinoa, acai berry, or whatever else happens to be this week's "fat-fighting superfood". To add insult to injury, most of the nutrition fads are not actually backed by real, reproducible science; suffice to say that in the 70s, table sugar was widely touted as a dieting aid. Even today, weight loss advice tends to revolve around robustly debunked concepts - say, the existence negative calorie foods, the alleged superiority of low-carb but high-fat diets, the evils of HFCS and aspartame, or the significance of eating meals on a particular schedule thoroughout the day.
In arctic or alpine areas, survival kits may have additional cold weather clothing (winter hats and gloves), sleeping bags, chemical "hand warmer" packets, sun glasses/snow goggles, snowshoes, a collapsible shovel, a snare wire for small animals, a frying pan, a camp stove, camp stove fuel, a space blanket, matches, a whistle, a compass, tinder, medical equipment, a flint strike, a wire saw, extra socks and a tent designed for arctic use.
