If you're one of those folks who didn't get a flu shot, then you'll probably want to check this out: the Google flu tracker, which shows the dreaded hack-cough-snort-bleagh virus as it makes its way across the nation, intent on whipping your immune system into a snotty mess.
It won't stop you from getting the flu, of course. But at least you can watch, helpless, as it stalks you. Ah, the wonders of the modern world.
