http://youtu.be/84aWtseb2-4 It's that time of year again: Everyone's groggily getting themselves to work an hour earlier than normal and trying to join in the collective delusion of Daylight Saving Time (as for why we do this to ourselves, see the video above). But as a statistician can tell you, get enough people all tired and confused at the same time and you will start to see some population-wide effects. Some studies, though not all, have found that at this time every year the number of traffic accidents spikes and that there are higher numbers of heart attacks and suicides. People also appear to waste more time on the Internet on the Monday when the clocks spring forward---researchers call it "cyberloafing"---perhaps because we have less will power when we are tired, and the Net is a sea of temptations. To all our Sleepy Monday cyberloafers coming to the site for the first time, welcome! We hope you'll stick around even when your circadian rhythm has reestablished itself. And while you wait: here are some videos of kittens we found while we were supposed to be doing something else.
