Workers of the world, come clean: Who among us hasn't laid our
head on the table, dozed off on a conference room couch, or curled up
behind our desk in the middle of the day? Don't feel guilty. You're not
alone. The Pew Research Center reported in 2009 that about 34 percent of
adults surveyed had napped during the previous day. We are an exhausted
crew. Most working Americans sleep six or less hours a night, instead
of the recommended 7 to 9 hours.
