LIFE expectancy in the United States has hit another high - more than 78 years.
The estimate of 78 years and two months is for a baby born in 2009, and comes from a preliminary report released last week by the Centers for Disease Control and Prevention.
About 2.4 million people died in the US in 2009 - roughly 36,000 fewer deaths than the year before.
Deaths were lower for a range of causes, from heart disease to homicide, so experts don't believe there's one simple explanation for the increase in life expectancy.
Better medical treatment, vaccination campaigns and public health measures against smoking are believed to be having an impact.
US life expectancy has generally been increasing since the 1940s, though some years it held steady and a few times it dipped.
