Healthy older people who burn higher amounts of energy in their day-to-day activities are much less likely to die prematurely than those who have a more sedentary daily regimen, according to an intriguing new study.
It is believed to be the first longevity study to use a novel, physiological laboratory method to measure how much energy a person actually expends daily rather than relying on potentially erroneous self-reported exercise estimates.
The study, which involved researchers at the University of Wisconsin-Madison, included 302 healthy men and women aged 70 to 82 who were followed for about six years.
