Apocalypse. That's funny. You know what? Those country folk in the mountains of Kentucky will survive. Those tribal villagers in Amazonia will survive. Those mountain folks don’t call it “bugging out.” They call it “the way we live every day.” Those mountain folks and tribal villagers have communities and time-tested skills that they all share, that have been passed down over generations. They know which plants not to eat, which herbs will cure a stomach ache, when the mating seasons of different animals take place, etc., etc., etc.
I have a book, a few articles I've read, and a few camping trips behind me. I've never spent significant time in the mountains or in the jungle. And I don't have a community of people with skills who will be assets keeping me alive. And what if the apocalypse does happen and I run to those mountains to live with the mountain folks? They'd shoot me on sight; take my shiny, little-used gear; and promptly throw me off a cliff. And I wouldn't blame them for it.
That said, I do have a few skills and a bit of knowledge (like knowing to purify water, the rule of threes, etc.) and a "bug out bag," if you want to call it that. Yes, there's a knife in there and some para-cord, but it's mostly for rigging stuff and getting me out of a jam in case my building collapses or something. It's not for building permanent shelters in the woods and processing wild game I've hunted down Rambo-style. It's designed to get me through a few days, maybe four at most, until I can get help. I've got three days of water in my house, plenty of candling and fire-making stuff, and some non-perishable food. I've got a hand-crank emergency radio, glow sticks, whistles, etc. I know the importance of having plenty of light, drinkable water, and signaling gear. I'm way ahead of the curve to survive the kind of crap that might actually happen to me... for a very short period of time until the authorities can rescue me. I won't be one of those dumb arses who doesn't even have a flashlight when disaster strikes.
But planning to survive an apocalypse for an indefinite period of time? If the apocalypse happens--and I don't find myself under the protection of the remnants of armed authority and supply chains--I'm dead. Period. I just hope death comes in the form of a beam hitting my head and killing me instantly... and not a slow death of dysentery, wandering around delusional and talking to myself in a bombed-out city... or being butt-raped to death at the hands of marauding, filthy post-apocalyptic biker gangs, à la Mad Max. But I don’t think the apocalypse is going to happen, so I’m not worried about those scenarios.
