Somehow there is no such fear elsewhere in the world, and despite this carelessness, no reported fan deaths! This means that either the world's fan manufacturers are in a conspiracy to hide the carnage (no doubt with the vaccine makers, the moon-landing fakers, and evolutionists) or that Koreans have a genetic weakness that allows them to be killed by a 5mph breeze. Patriotic Koreans no doubt find option #2 unpalatable, so we must find the conspiracy!
Oddly enough, as I write this, I recall that the electric fan in my room while I was growing up was a Samsung. I frequently left it on overnight. I am therefore undead. A vampire fan manufacturer conspiracy! It's the only explanation!
I have a fondness for obscure conspiracy theories and superstitions so I love this one. I leave it to some brave member of the skeptical community - maybe right here in San Diego! - to film themselves sleeping with multiple electric fans pointing at them and wake up alive. Like Jackass meets skepticism!
