I don't usually write book reviews, but I feel like this is important. Book seems to have been written off the top of author's head, from memory. First, it is not "Long Term" survival at all. I have a lot of questions that I am searching for answers to, but there are areas that I am quite knowledgeable and experienced in and I found a number of careless errors in what is written in this book (particularly in food and medicine). This causes me to not trust the author's recommendations in areas I DON'T know about. Also, most information is not detailed enough to be much of any kind of guide for survival. I've seen other reviews complimenting Mr. Cobb on other book(s) he has written-regarding home defense-for the sake of those looking for accurate information for times of emergencies, he needs to stick with what he knows, or do better research before writing books that people might depend on for survival.
I know that in my own case and also with the majority of the readers on Backdoor Survival, hunkering down and bugging in will always be preferred to taking off into the unknown with our stuff.  For many, the choice to bug in has to do with family, health concerns or financial considerations.  That, plus the availability of stored supplies makes bugging in – or staying at home – the choice when a disaster strikes.
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.[30] 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. [32]
The difference between the male prepper stereotype and this softer, more feminine strain of survivalism, Mitchell explains, is that women’s work never stops being useful. “We don’t need the pickup truck and the chainsaw and the assault weapon every day, but every day someone must love the children,” he says. “Every day we must feed ourselves and care for ourselves emotionally. There is no crisis that can possibly exacerbate the [need for] women’s traditional roles, because they’re always needed. Do we need the men? For practical purposes, maybe not.”
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)]
