A University of Illinois at Chicago study found the life expectancy of white women who didn't finish high school dropped five years between 1990 and 2008, to an average age of 73 and a half years. By comparison, white women with a college degree live nearly 84 years.
White men without a high school diploma lost three years, living about 67 and a half years, while those with a college degree live to be 80.
Researchers say they're baffled by the drop.
