I saw the meme to the right on social media (probably Facebook) and thought that I never assumed my grandparents weren't smart. They just knew different things than we do today. For example, I couldn't can food if I had to. But I'm sure my grandparents would have trouble figuring out a smartphone. They were a different kind of smart.
One hundred years ago there were things you had to know to survive that we, in the 21st century, have forgotten. We're going to be in trouble if civilization collapses. Another thing I've seen on Facebook: "I can't hunt for food, I don't even know where tacos live."
My grandfather had to deal with complicated farm equipment. I know how to change the oil on my car (I don't do it anymore) and I have done brake work on cars. But growing my own food would be beyond me. I'd have to learn quick, and without Google, if an EMP took out our electrical grid.
And that's the magic of books. I'd head for the library and look for books on planting and harvesting food. Unfortunately, all of the library's book catalogs have been computerized, so I'd be searching blindly. But I'd still be searching.
(One problem is the library is about five miles from my house and I assume I couldn't drive there.)
Other things my grandparents knew that I don't include animal husbandry. Taking care of cows, horses, etc. Yes, there are people who do that today. If the EMP goes off, I think I'll try to make friends with some.
So never assume people weren't as smart in the past. It was just a different kind of smart.
How do you think you'll do if civilization collapses? Let me know in the comments below.
