I grew up on Canadian air force bases, my Dad was a radar technician. Nuclear war was a daily reality for us. Because we were the base for the Argus, and then the Aurora, both submarine hunting planes, we were told that we would be included in the first strike of nuclear bombs. The air raid/nuclear bomb warning would go off on a semi regular basis, mostly as a test. We were taught "Duck and Cover" in school, to hide in place under your desk.
The result of this is that until the Berlin Wall fell, myself and many of my friends lived with a fatalistic viewpoint of the world, and most of us were involved in getting our kicks in before the whole sh!thouse went up in flames. We never thought of bugging out, we knew from the myriad presentations we had at school and at local air shows that the devastation would be complete, the only thing that could be disputed is whether you would die instantly or linger for a time with radiation poisoning.
When the Berlin Wall fell, a great weight was lifted off my shoulders, and I was finally cured of my nuclear annihilation disorder. It was no small thing. With the state of the world today, one could develop NAD pretty quickly, but I'm not falling victim this time. I have faith, perhaps displaced, that the world will not go down that path.
If it did, forget about escaping, there are no safe places anymore. When covid first started, I watched two middle aged chubby women wrestling over toilet paper in the grocery store. I have a place picked out to weather the storm, only accessible by canoe, but lets be realistic, I'm getting on in age, I would probably die a horrible death during the first winter. A group of free love hippies came up here in the early 70's and tried to survive a winter on the shores of the Namewaminikan river. My mentor has spoken to them in the spring, there were about 30 or 40 of them, all from the US, trying to live off the land. They were gone by February.
So this long ramble is all to say I don't worry about anything much anymore, I'll just deal with stuff day by day, enjoy life as much as I can, try to do no harm. The air is thick with smoke from forest fires fires today, but pretty sure I'm still going fishing in my freighter.
