Not taking a cheap shot at the author, but wouldn’t the author fall into 1 or 2 of these categories? I think the human character of every individual harbors a little bit of all or several of these. Most, if not 100% of anyone prepping has in their specific individual plan – their family members. Each family member brings their own set of considerations (assets & liabilities) to the table. Are we to avoid/cast out these family members due to their nonconforming attributes? This eludes me to one of the categories you left out – The resistant/reluctant prepper. Because if you have a family there’s a strong chance you will have one of these, but they too come around in time.

If you have a friend, (in our case a family) and one of them is Bi Polar, consider NOT partnering up with them,. Even if one of the adults is very well versed in many survival skills.and the adult who is Bi Polar is good at thinking on the fly. No matter how well balanced and in hand the one seems, at some point their condition will manifest and it could well spell out major problems over all. If they are addicted to CHAOS (and many of them are), they will go out of their way to CREATE issues of some type within the group that will do NOTHING of value to insure survival

GPS is great but what happens when your battery dies, and you don’t have a portable battery handy? The compass is the one piece of survival gear that will never let you down. Sure, it can’t tell you if there’s a town nearby but it can prevent you from wandering aimlessly in circles. The Eyesky compass is designed specifically to help extricate you from emergency situations. It features conversion charts to measure distances, a rotating bezel ring to determine your heading and adjustable sight lines to plot your course. It’s also built to last. It will take you all of an afternoon to learn how to use the Eyesky compass and it may turn out to be the most valuable afternoon you ever spent.

Again, the reason we tend to look sideways at those who get a little too into prepping for an apocalypse is because of their smug optimism. People actually being realistic about a dangerous future would be better served joining the military or ingratiating themselves with high-level government officials than agonizing about a little mouth scuzz or foot fuzz, right?
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.
This group has a primary concern with maintaining some form of legal system and social cohesion after a breakdown in the technical infrastructure of society. They are interested in works like The Postman by David Brin,[46] Lewis Dartnell's The Knowledge: How to Rebuild Our World from Scratch,[47] or Marcus B. Hatfield's The American Common Law: The Customary Law of the American Nation.[48]
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.
The U.S. Department of Homeland Security (DHS) in their "If You See Something, Say Something" campaign says that "the public should report only suspicious behavior and situations...rather than beliefs, thoughts, ideas, expressions, associations, or speech...".[84] However, it is alleged that a DHS list of the characteristics of potential domestic terrorists used in law enforcement training includes "Survivalist literature (fictional books such as Patriots and One Second After are mentioned by name)", "Self-sufficiency (stockpiling food, ammo, hand tools, medical supplies)", and "Fear of economic collapse (buying gold and barter items)".[85][86]
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!
