If it weren't for the internet and Jeopardy!, I wouldn't have learned much since leaving school. Well, nothing impractical and interesting, anyway. Sure, I've learned a lot about the work force and work-life balance and how to realize when a job is draining your soul, but not so much in terms of the fun facts.
So, thank goodness for the folks who want to put interesting stuff on the internet and share it with the world. These are the things that keep my brain somewhat engaged with life outside the daily grind, and they're very welcome.
