As a recycling of old folkolishness, a recent report is that male laptop users who put their laptop in their lap were observed to have suffered an apparent reduction in fertility.

It sounds lke a recylcling of the tales my dad told about the myth that "you won't get her pregnant if you dangle your balls in the Model T radiator before ... ."

(Claims were that a few of his buddies may have tried it. No reports of successful use of the method - or of really serious injuries.)

Long sessions of staring at something at relatively close fixed distance have also been implicated in an apparently increasing occurance of premature near-sightedness, although it's not clear that the reports have separated the "monitor effect" from the similar natural aging effects. (Claims of this result have probably been around since the invention of books; but that doesn't mean it's not real.)
