We may be a few days behind in catching up on worldwide sex-related death news stories, but we'd be remiss if we didn't remind you to be careful where you have sex--that is, unless you want to end up like the South African couple who were killed by a train while doing it on train tracks. Police told the local papers that the couple ignored the driver's shouts and "continued with their business." Remember: sex in the train is a better bet.
