The study, led by researchers from Griffith University in Australia and various institutions worldwide, challenges previous estimates of physical activity’s benefits, which were largely based on self-reported data. By using more accurate device-based measurements, the researchers found that the relationship between physical activity and mortality is about twice as strong as earlier studies suggested.

Consider this: The most active 25% of Americans over age 40 engage in physical activity equivalent to about 160 minutes of normal-paced walking (at 3 miles per hour) every day. If all Americans over 40 matched this level of activity, it would boost the national life expectancy at birth from 78.6 years to nearly 84 years.
