Porn Makes You Blind

Well, ain't that a helluva note? First it's masturbation, then Viagra, and now it's porn! Well, okay, porn won't make you blind quite the same way the other two will (said by someone with severe myopia). It "confuses" you so that you can't pick out a picture of a certain building, if there's a porn picture in the stack close to it. Someone in the US (that means with an ax to grind) tested volunteers to see of they could pick out a photo of a specific building from a stack of a hundred or so photos. The test really was to see if they could pick it out after having seen a porn photo shortly before. I wonder if handling the photos makes hair grow on your palms.
