For years a stereotype of aging is that you get tired as you grow older.  But new research analysis is putting that stereotype to rest.

Laura Kurdna is a researcher at the London School of Economics and Political Science who recently analyzed answers from the 2010 American Time Use Survey, a national survey sponsored by the Bureau of Labor Statistics.  This particular survey was the first to ask people about their energy levels.  Each person in the study kept a daily journal of what they did the previous day, how they felt about those activities and how tired they were while doing them.

Americans ages 65 and older reported being less tired than older teens and young 20-somethings.  Interestingly, tiredness dropped off after age 40 and continued decreasing with age.  Read more in this L.A. Times article, and here's a link to the study.
