very very few people had any ability to look after themselves
Have you SEEN how helpless people are now?
There are people I see on community facebook groups that hire an electrician to come change lightbulbs in their bedroom ceiling fixture because they're terrified of even taking a light shade off. Or they hire a plumber to come and replace the ($10 at Home Depot and 30 seconds to replace) flapper in their toilet. Pool pump won't prime - call the pool store and have them rush over a tech for $150. Car won't start but the one parked next to it will....call CAA and wait for a boost even though a neighbour likely has a set of booster cables. Ditto a flat tire even when there's a perfectly good spare and all the required jacks and tools in the trunk - they've ZERO idea how to even get to the spare tire, much less replace it on the side of the road.
I often think that if there was ever an actual doomsday situation upwards of 80% of the population would be dead inside the first 2 weeks. 10% of the remainders will survive but not comfortably. The rest of those who have the skills and know-how to survive (or even thrive) in tough times will be doing just fine....
Has anyone else ever read the Mountain Man series by Kenneth Blackmore? I'm that guy....well, minus all the booze. Probably.
