There's always something new you can learn. Something that can broaden your horizons. You just have to know where to look.

One of the places that offer a never-ending flow of knowledge is the subreddit 'Today I Learned' (or TIL for short). People go there to share all the interesting stuff they discover, and the fact that its members are the ones who produce its content is what makes TIL such an enjoyable encyclopedia. It's legit. It's unpredictable. And it's constantly getting new submissions. What more could one ask for?

Continue scrolling to check out some of its hottest new posts and if you want to continue your "studies", fire up our earlier pieces on the subreddit here, hereand here.
