A new study finds we are living longer.

Researchers at the University of Washington found Americans are living about three years longer than they did 20 years ago. Life expectancy in the U.S. increased from 75-years in 1990 to 78-years in 2010.

The study also found more than two dozen countries have higher life expectancies including Australia, Germany and Iceland. Japan tops the list at about 82-years.
