When someone works in a specialized field for many years, they'll end up gaining highly specific knowledge and a unique understanding about how certain things work. While most of the population might live most of their lives believing a common misconception about how things get recycled, a garbage collector somewhere out there is probably tearing their hair out about how dumb we all are. There's a lot of instances of this—and while one person might be an expert in archaeology, chances are they don't know a dang thing about the trucking industry. And that's why this recent AskReddit thread is so wonderful—a bunch of people from different industries came together on the internet to share facts that are common knowledge in their respective fields, but mostly unknown to the rest of the population. The thread is super fascinating and we hope you enjoy it as much as we did!
