Medical Journals: How Fast You Walk Is How Long You’ll Likely Live

(By the Easy Health Options: First published in article dated 4 Jan 2012 -

If you’re one of those people who stroll very slowly down the block, you better pick up the pace. Something may be gaining on you. Research shows that the slower you walk, the sooner death is likely to catch up to you.

In an analysis of the health history of more than 34,000 people over the age of 65, researchers at the University of Pittsburgh found that faster walkers had greater life expectancy.

According to these scientists, there are several reasons why walking speed may predict survival. "Walking requires energy, movement control, and support and places demands on multiple organ systems, including the heart, lungs, circulatory, nervous, and musculoskeletal systems. Slowing gait may reflect both damaged systems and a high energy cost of walking."

In this study, if you walked slower than about 2 feet a second, it was time to start making sure your affairs were in order: And you only had time for a couple of more walks.
