New Study Finds More Intense Physical Activity Reduces Death Risk Among Older Women

A new study from Harvard researchers found that just one brisk walk a week could cut an older woman's risk of early death by nearly 70%. The study concludes that more physical activity, especially at increased intensities, could lead to an increase in life expectancy among older females.

Previous studies have found that self-reported active people have about 20 to 30% lower death rates than those who were least active.
