This. Especially when I realize that there is a thing the explanation for which was given to me by someone way before either of us had access to the internet and before Google existed (I am getting old I guess). Like whether eating onions helps stave off a cold. Or how a distributed in a car works. Or whether Nissans are actually reliable or not. Or if you need higher than minimum recommended octane rating in your car. Or why most of Europe uses 240V in their outlets. Or what actually happened in Chernobyl.
