OK, not everybody is a runner. But most people can walk pretty fast or do other weight-bearing excercise to strengthen bones, tendons, and muscles. Those who do it have a longer, more enjoyable life.
A new study by Stanford University followed middle aged males beginning in the 1980's. One group of men in the study were runners and the others were not. Over time, there were just half as many deaths from all causes among the runners versus the nonrunners. Even more significantly, disabilities in the runners occurred 12 to 16 years later than in nonrunners. Doctors at Stanford were surprised by the longevity effect and especially surprised by the quality of life the runners experienced.
At the time the project began, those who opposed it predicted the men who ran everyday would suffer serious injuries and many would require knee replacements. As it turned out, the result was just the opposite. Runners did not have higher rates of osteoarthritis or knee replacements. Other who criticized the study said that the runners may have been in better shape to begin with, but all study subjects were deemed to be in good health in 1980.
This study is one more example of how simple things like exercise make a big difference in future health. What is not so simple, is taking the time and self-discipline to exercise on a regular basis. Those inspired by the runner's story should remember to check with their doctor before starting an exercise program - and go slow at first.
As the old saying goes, you have to walk before you can run.
