Scientific studies show that if a person maintains jogging exercises three times a week for many years, that person will increase his life expectancy by six years.  Scientific studies also show that if people maintain the same jogging routine, or a similar exercise routine, it will reduce average medical costs by 53%.  A Microsoft survey covering over 30,000 people, those employees said they only averaged 2/3d productivity every week.  An employer would be wise to require the employees to exercise on the clock.  It saves money and improves productivity.
