Americans are sleeping just a bit longer than they have in the past.  The U.S. Bureau of Labor Statistics' annual American Time Use Survey has found that Americans slept an average of eight hours and 44 minutes per night in 2013.  It marks an increase of ten minutes from when the same survey was conducted ten years earlier.  It also finds that time devoted to leisure has gone up.  American are now devoting an average of five hours and 16 minutes to activities like watching television and exercising, up by nine minutes from a decade ago.  As for child care, the survey finds that there's been a slight shift balancing the responsibilities between men and women.  Women spend an average of two hours and 17 minutes caring for their families, down by about two minutes from 2003.
