The Pew Research Center is back with some groundbreaking news to share. Apparently, people who happen to be unemployed tend to nap a little bit more during the week than those who have jobs to go to every day. But people who work regular jobs from Monday to Friday typically nap a bit more on weekends. Crazy, huh? Then again, as the Times reports today, the study didn't really explain what a nap is: "The survey did not precisely define what constitutes a nap. Some people claim they are just resting their eyes when they are really snoozing. Others may doze momentarily when reading articles about demographic trends." [NYT]
