The increased inflation rate in the 1960s, the US monetary devaluation, the continued concern over a possible nuclear exchange between the US and the Soviet Union, and perceived increasing vulnerability of urban centers to supply shortages and other systems failures caused a number of primarily conservative and libertarian thinkers to promote individual preparations. Harry Browne began offering seminars on how to survive a monetary collapse in 1967, with Don Stephens (an architect) providing input on how to build and equip a remote survival retreat. He gave a copy of his original Retreater's Bibliography to each seminar participant.
Zombie apocalypse: Used by some preppers as a tongue-in-cheek metaphor for any natural or man-made disaster and "a clever way of drawing people’s attention to disaster preparedness". The premise of the Zombie Squad is that "if you are prepared for a scenario where the walking corpses of your family and neighbors are trying to eat you alive, you will be prepared for almost anything." Though "there are some... who are seriously preparing for a zombie attack".
Your run-of-the-mill shoe stank might not pose much of a survival threat, but trench foot certainly will; baking soda is great at absorbing the moisture that might otherwise literally cause your feet to rot off your legs. As for the health of your teeth -- it will be pretty hard to get through your day's rations of homemade jerky and hardtack without some high-quality chompers. And you certainly don't want to rely on that pesky fluoride that will "kill your brain over time" (um, what?).
Lightweight survival kits are generally seen as a backup means of survival; however, these can kits can be extensive, and have come to include tools that are generally found in larger kits as survival technology advances. Some examples of these tools are high power flashlights, rapid use saws, signal devices such as mini signal mirrors, and water purification methods.
I am guessing, I am the homesteader. Or, I would call it “shelter in place prepper”. Since, I am in advanced age, I don’t have the mobility of a 20 year old, to bug out. The problem, I see with a homesteader, is if you don’t have the arms and man power to defend what you, then it will all be taken away. Reason, I am into hiding food in plain site. Pecan trees, oak trees, black berry patch, mushrooms, and such.
This group stresses being able to stay alive for indefinite periods in life-threatening wilderness scenarios, including plane crashes, shipwrecks, and being lost in the woods. Concerns are: thirst, hunger, climate, terrain, health, stress, and fear. The rule of 3 is often emphasized as common practice for wilderness survival. The rule states that a human can survive: 3 minutes without air, 3 hours without shelter, 3 days without water, 3 weeks without food. 
If you’re ordeal is an extended one you can lash the Ultimate Pro Knife to a small branch to create a spear for catching fish or small mammals.

A top-notch knife like this is essential survival gear.
Preparing for catastrophic or short range survival is extremely personal and most of us keep it tight to our chest. I think PowderKeg says it best – Invisible and then Nuttus who knows that not all of us are the same skill or wherewithal stage, yet as a TEAM we shore up each others weaknesses, learn off each others strengths and it is a continual building process going forward.
Bombs rain from the skies, alien ships descend with lasers ablaze, improbably proportioned, irradiated sea monsters tear through essential infrastructure. You'd think that running, screaming, and finding clean underwear would top the list of activities likely to improve your chances of living, followed closely by finding a sustainable food source and offering sexual favors to the person with the most impressive arsenal. Unless you were a prepper, in which case you'd be worrying more about the safety of your cigarette stockpile.

DIY home surgeons will be excited to know epinephrine can actually be used with lidocaine (a numbing agent) to restrict blood vessels for faster wound repair. (Note: Cracked in no way condones performing self-surgery.) When sanitization resources become limited, the speed with which a wound can heal will have a drastic impact on survival rates. The longer a wound stays open and bloody, the more likely you are to get infections. Infections have historically been some of the most deadly and difficult-to-treat medical conditions, and even today they are not always easily survivable.
However, that may all there be to it. When it comes to other serious survival skills, especially knowing what to do in a bug out situation, they may be lacking. The negative side of this type of survivalist is they love their home so much that they might refuse to bug out, even if the situation calls for it. Overall, the key is to develop the skill to determine whether you should bug in or bug out.
Paracord is one of the most versatile pieces of survival gear you can carry. It has applications as diverse as helping you set up a makeshift tent to creating a clothesline for drying wet clothes to establishing a perimeter around your campsite that will warn you of the approach of curious or hungry mammals. On top of that you can use it to transcend physical obstacles like small cliffs you might encounter as you attempt to reach civilization. It’s essential survival gear for the person that likes to be prepared for any eventuality.
