U.S. life expectancy declines for the first time since 1993.

For the first time in more than two decades, life expectancy for Americans declined last year — a troubling development linked to a panoply of worsening health problems in the United States.
Rising fatalities from heart disease and stroke, diabetes, drug overdoses, accidents and other conditions caused the lower life expectancy revealed in a report released Thursday by the National Center for Health Statistics. In all, death rates rose for eight of the top 10 leading causes of death.
