As in, why do so many people admit that they think the idea is ridiculous but still make sure they've at least got a window open? Or, as one blogger put it:
Sometimes what we believe without any questioning might not be true. Therefore, we should check at least one time whether what we believe so naturally is really true or not.
Regardless of it, I would like to recommend opening the windows when you sleep with the fan in summer. As a matter of fact, sleeping while drunk in the hot summer is such a dangerous behavior (maybe the drunken people even don’t have sense to open the window). It doesn’t matter whether you have a fan or not. Even when you use the fan, place it near your feet, and so your face is not going to be swollen the next day ...
I have to admit, since my daughter was born, I fall into the 'I think it's bunk, but hedging the bets anyway' category. When I moved here almost three years ago, I thought belief in fan death was one of the most absurd things I'd ever heard. I mean, it's not like it's some superstition left over from the murky mists of time. We're talking about a fear of electric fans.
But now that the weather is so hot that we need a fan in my infant daughter's room, I just can not bring myself to completely shut the door when it's on. I leave it open, you know, just in case there's something to it.
I had some half-baked, pseudo-intellectual argument worked up about the power of culture and socialization versus the individual, and how the surrounding culture inherently shapes the way you think---sometimes against your will, sometimes without you even knowing it. But, this is probably a lame example, so I'm not even going to try to explain it.
All I know is, although I'm glad to have it, I totally don't trust that fan.
