New research reveals contributors to shorter life expectancy for Americans
UNDATED - New research shows guns, drugs and cars contribute to a shorter life expectancy for Americans.
Life expectancy for American men is 76.4 years, compared to 78.6 in other developed countries.
For American women, it's 81.2, which is compared to 83.4 in other countries.
Researchers say injury-related deaths are to blame for the gap because they happen more frequently in the United States.
