A new study suggests that too much   jogging can lead to early death. 
Researchers from the Cardiovascular [kahr-dee-oh-VAS-kyuh-ler]   Research Institute at the Lehigh [LEE-hahy] Valley Health   Network in Pennsylvania [pen-suh l-VEYN-yuh, -VEY-nee-uh],   found that too much running can result to shorter lifespan. They said that this is just as bad as doing no   jogging at all.   
Dr. Matsumura and his team studied   3,800 runners, both men and women, who have an average age of 46. Almost 70%   of the participants regularly run more than 20 miles a week. The medical   histories of all participants were obtained   to determine their health conditions. They were asked about the medications   they were taking and some other health issues such as high blood pressure and   high cholesterol.  
The results show that none of the   health factors have any direct correlation   to running and the short longevity of the subjects. Admittedly, the   researchers themselves still cannot figure out the reason for this   connection. Dr. James O’Keefe believes that the findings could be due to wear and tear on the bodies of people   who run excessively. 
Matsumura said that the study do not   suggest that people should not run anymore. Instead, he suggested that people   run moderately for two to three   hours a week. He also added that runners should be updated with the latest   studies linking lifespan to excessive running.
