As the world seems to be coming to a semi-swift, very hot, and masked-up end, it's important to remember that many people throughout history have thought that they were about to see the end of days. Back in 1910 astronomer Camille Flammarion, whose name seriously sounds like a Pokémon, thought that Halley's comet would obliterate life on Earth. It didn't. In the Middle Ages, the world ended for almost 1/3 of Europe's population, thanks to the Black Death. Somehow, the world managed to go on. More recently, Y2K and the "end" of the Mayan calendar both inspired panic regarding the end of days. We made it. Basically, what we're trying to say is that almost everyone has lived through some kind of horror. Now, all of those fun wars, plagues, and disaster are used as fodder for our favorite things: memes.
