You probably get it by now, but we're going to keep rubbing your face in the facts, nonbeliever. A bit of body odor might seem like a minor inconvenience, but it gets a whole lot more important when sneaking up on an animal that hasn't spent the last millennia losing its survival instincts means the difference between feasting and starving. Finally, an accidental fire near your ammo stores that could easily have been extinguished with a dose of nonflammable powder will certainly put a damper on your plan to make it through the end times in one piece.
It turns out that when you're down to your last moldy hunk of bread and giardia-laced mud puddle, letting it all melt away in a cloud of smoke for a few precious moments can mean the difference between giving up and giving the rat (eating) race another go. If history has anything to say, it's more common than you think for people to happily give up MREs and gunlord harems in return for hastening their ends with carcinogens wrapped up in tidy paper packages. In traumatic situations like war, cancer sticks are often valued more highly than food. Even in the current (more or less) pre-apocalyptic global economy, cigarettes are one of the stable forms of currency.
For global catastrophic risks the costs of food storage become impractical for most of the population  and for some such catastrophes conventional agriculture would not function due to the loss of a large fraction of sunlight (e.g. during nuclear winter or a supervolcano). In such situations, alternative food is necessary, which is converting natural gas and wood fiber to human edible food.
Firearms instructor and survivalist Colonel Jeff Cooper wrote on hardening retreats against small arms fire. In an article titled "Notes on Tactical Residential Architecture" in Issue #30 of P.S. Letter (April 1982), Cooper suggested using the "Vauban Principle", whereby projecting bastion corners would prevent miscreants from being able to approach a retreat's exterior walls in any blind spots. Corners with this simplified implementation of a Vauban Star are now called "Cooper Corners" by James Wesley Rawles, in honor of Jeff Cooper. Depending on the size of the group needing shelter, design elements of traditional European castle architecture, as well as Chinese Fujian Tulou and Mexican walled courtyard houses, have been suggested for survival retreats.
The 5-in-1 paracord bracelet slips on with ease and stays fashionably in the background until or unless the situation on the ground takes a turn for the worse. That’s when they spring into action.

Gerald Celente, founder of the Trends Research Institute, noted how many modern survivalists deviate from the classic archetype, terming this new style "neo-survivalism"; "you know, the caricature, the guy with the AK-47 heading to the hills with enough ammunition and pork and beans to ride out the storm. This [neo-survivalist] is a very different one from that".
Say you're at work and a terrorist attack occurs. Roads are closed to any and all traffic but you only want to get home - even if that means walking. You may not want to grab your full on family pack in the car or you may not even be able to get to it. But you just want a light kit to get you through. How far is it to get home from wherever you may be? This get home kit should provide for 1-3 nights of traveling on foot till you make it home.
