Here is another way you are killing your sperm: "Working on a laptop wirelessly may hamper a man’s chances of fatherhood. In a study, sperm placed under a laptop connected to the internet through wi-fi suffered more damage than that kept at the same temperature but away from the wireless signal. The finding is important because previous worries about laptops causing infertility have focused on the heat generated by the machines."

The Chicagoland rail system Metra, thanks to some budget constraints and a refusal to bombard passengers with the sort of infotainment they're confronted with in elevators, won't have on-board wi-fi anytime soon. This even though a study commissioned for the state of Illinois claimed that doing so could "have positive impacts on traffic congestion, traffic safety, the economy, and other aspects of the quality of life Illinoisans enjoy." (Look at the "positive impacts" being experienced by the man in the photo at left, which was borrowed from a sales pitch for a company that provides this service!)
