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.

Catastrophes and their aftermath are never predictable, but having appropriate gear on hand serves as versatile preparation for conditions ahead.

Before an economic collapse, pandemic, or natural, chemical, or nuclear disaster hits, browse through our selection of equipment to prepare.

The primary purchasers of the product are water treatment plants. Pool owners are just discovering it, but most aren’t seeing the advantage of having a non-degrading bleach supply. Once they start figuring out the savings from buying calcium hypochloride, and the retail price comes closer to the cost of pool chlorine, calcium hypochloride will become a hot seller.
I had the blessing of knowing my grandparents who lived through the Depression. I was a prepper before it was a ‘thing’. I always had a pantry to rely on. When I actually ‘got into’ prepping, I went overboard, was a bit fanatical, and then I got burned out. Too many ‘doomsday’ articles and sites. I have since changed my approach to more of a ‘homesteader’ mindset. Homesteaders and preppers have a lot in common, and the ultimate goal is the same, to be more self sufficient.
For example, have you considered the need for feminine products?  What about canes, walkers, and manually operated wheelchairs?  Pets need food, crates, and toys to keep them occupied while the rest of family members are recovering from chaos.  It will be impossible to cover every contingency but be aware of what those needs are now then prioritize those that you deem most important.
For ideas, take a look at 12 Months of Prepping: One Month at a Time. Here you will find links to articles that take you though the process of gathering what you need in terms of supplies, gear, tasks, and skills to set you on a positive path of preparedness.  It may not seem like a lot, but at the end of the year you will will be better prepared than 95% of your neighbors.
When I go offroading/tent camping, I usually bring an ice chest with real food, but one of my friends always brings Mountain House freeze dried food and gives very high ratings for it. So I bought the "classic assortment bucket" just to try out. The meals taste as good as Hamburger Helper with fresh ground beef. The seasoning is spot on and the sodium content fits with the typical American diet which tastes good and helps you retain water. This is good in a survival situation. It's bad for people with heart failure, but it's really good for healthy people that are starving and have limited water supplies. Skeptical that I know what I'm talking about? I'm a molecular biologist and a board certified sub-specialist medical doctor trained at University of Washington, UC Irvine and Stanford (you can Google me). The "per serving" numbers ... full review
When somebody speaks of a ‘credit collapse’ , I don’t think anyone can possibly speculate or define what that possibly might be, or how much, or where, or really anything specific enough to be meaningful. The problem with this type of hysteria and hand-waving, is that without specific definitions, or possible implications, it leaves any listener up in the air, grasping at ghosts, and no real solution. So all it does is provoke anxiety, as you can’t possibly prepare for any potential threat or ‘enemy’ that you don’t know anything more about than someone’s vague notion. Further, Its impossible to prepare for every single scenario, that anyone can imagine, let alone even be possible for worst case, as no one has a clue what worst case is, or will be. If any reasonable business leader such as a CEO attempted to prepare for such vague notions as mentioned here, the CEO would be ruled insane, and the board would summarily fire him. Instead of doing this scene here, listening to what will almost assuredly turn out to be in hindsight, false prophets, and making your day a nightmare, why not live each day as if its your last, live in the moment, enjoy it and your time with your family, or work colleagues, and make the best of THAT MOMENT ? I’d be shocked if at least 75% of the listeners here, weren’t either seeing a shrink or taking anti-depressants or anti-anxiety medications of some sort. Its not a knock, but seriously people, try taking a ‘chill pill’ (placebo and call it that) like a Vitamin C, or have yourself a glass of wine, at the end of the day.

Since people began building fallout shelters during the Cold War, canned nonperishable food has been recognized as great to have around when the going gets tough. Freeze-dried food and MRE (Meal, Ready-to-Eat) military rations with years of shelf life are also good options that take up less space per available calorie. [Doomsday Facts (and Fictions)]
