Life expectancy increases-- for some

Life expectancy in the United States is on the increase, but only among people with more than 12 years of education, according to a new study published in the March/April issue of Health Affairs.

It also found those with more than 12 years of education -- more than a high school diploma -- can expect to live to 82. For those with 12 or fewer years of education, life expectancy is 75.

Researchers say about one-fifth of the difference in mortality between well-educated and less-educated groups can be accounted for by smoking-related diseases. The other difference may be connected to crime, worse access to health insurance and health services.
