Too many these days have absolutely no idea how any of the infrastructure they rely on works. Even when you try to explain to some, their attitude can be to bury their head in the sand as they are just too lazy to learn. I now leave them to it, and just behave like an insufferable ass when they later come to me for help.
If you have no idea how to deal with a water leak, gas leak, power outages, freezing conditions, flooding, etc. then it's your funeral. When these things happen, the Internet may not be available, so it'll be too late to look it up then. I'm not a prepper in terms of food, etc. but I am in terms of knowhow!
In my teens I did wilderness survival training, both team and solo. Solo is hard! I lost weight on every single solo exercise I did.
On one team exercise we caught a wild sheep and ate like kings. Because of that, the hardship of finding food every day was substantially reduced, so I got bored and made a waterwheel generator from found junk that powered a flashlight bulb. <LOL>
