Earthquakes, tornadoes, and hurricanes can cause you to leave your home or even be trapped there. Roads could be blocked due to fallen trees, power lines, or even damaged earth from the natural disaster. Rescue crews can not be in all places at once. You may have to wait it out for quite a while before its over. You won't be able to go to the store or to the corner market.
Also, many who come out here don’t seem to have taken into account ONE aspect that has already marked and recorded their interest in this/these skills. We ALL listed that we came out on here to learn in the least about it and data doesn’t get deleted or lost. (Just saying, we do have a digital fingerprint complete with email, IP address, and every letter typed.)
The kind of gear you need – It’s easy to get obsessed with survival gear and start accumulating every new product that comes on the market. If you have money to burn and engage in a variety of backcountry activities this might be a sound strategy. Most people however decide pretty early on what type of outdoor activity floats their particular boat and as such any survival gear should have some sort of relationship to that activity. Everyone, for instance, should have an emergency whistle with them but not everyone will need an extreme sleeping bag. Everyone will need first aid items but not everyone will need to carry croval shovel or a tactical watch or field watch. If you’re a mountaineer you’ll probably want that shovel, especially if you’re climbing in the winter. If you’re going on a day hike and aren’t bringing food that requires preparation there’s no need for a mess kit and so on.
People who carefully and painstakingly prepare for mass extinction don't exactly seem like the type of people who plan great parties. At least, with those vast collections of guns, ammo, and other terrifying armaments, I certainly hope not. Then again, I suppose everyone will need a drink or 10 to get through the inevitable horrors of forever navigating the "what's for dinner" question without Seamless or, you know, realizing that your urban-dwelling family members will probably never arise from the blasted pit of rubble where their apartments once stood.
However, if some tales of survivalist stockpiling are to be believed, our nutty neighbors have enough of the social lubricant squirreled away to hold the most epic end-of-the-world-party of all time outside of Edgar Wright's social circle. It might not be practical, but who needs practical when you and everyone you know is doomed to die from radiation poisoning or cancer?
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.
To me, the best option is to store emergency food. How much? If you have none, store enough for a few days. If you have enough for a few days, get enough for a week. How much you store depends on what time frame you think you're at risk for having to be completely independent. The early settlers of the southwest liked to store enough food for a whole year and still do to this day!
