To Age Well, Walk – NYTimes.com

You don’t need a weatherman to tell which way the wind is blowing – and a scientific study of benefits from walking is not needed to know it is good for you – duh. When humans left East Africa and populated the globe – what was their principal means of transportation – two feet!

The results, published on Tuesday in the journal JAMA, reinforce the necessity of frequent physical activity for our aging parents, grandparents and, of course, ourselves.

While everyone knows that exercise is a good idea, whatever your age, the hard, scientific evidence about its benefits in the old and infirm has been surprisingly limited.

“For the first time, we have directly shown that exercise can effectively lessen or prevent the development of physical disability in a population of extremely vulnerable elderly people,” said Dr. Marco Pahor, the director of the Institute on Aging at the University of Florida, Gainesville, and the lead author of the study.
