CBS reported about research that shows that many people get crankier — quite a feat in the winter-weary Midwest — when daylight saving time kicks in, as it did Sunday. We also tend to succumb to “cyberloafing,” which means committing the highly unusual act of wasting time of the internet. (The study’s authors apparently didn’t correct the data for the phenomenon called “March Madness,” a truly worthwhile activity). The messed up sleep accompanying the time change can make you more likely to have a stroke, get in a car crash, and crave comfort food. That last one might also be caused by “March Madness,” but the research didn’t address that.
