More than 55,000 adults ages 18 to 100 were followed during a 15-year period to determine whether there is a relationship between running and longevity. Participants in the study were asked to complete a questionnaire about their running habits, and researchers kept track of those who died during the study period. About a quarter of the group were runners. The researchers found that people who did not run had a life expectancy three years less than that of runners. Running was linked to a 30 percent lower risk of all-cause mortality and a 45 percent lower risk of death from heart disease or stroke. Running a minimum of 30 to 59 minutes per week (5 to 10 minutes per day) was associated with a 28 percent lower overall risk of death and a 58 percent reduced risk of death from heart disease compared to no running.

The influences of obesity and age on functional performance during intermittent upper extremity tasks 

Obesity not only has an impact on a person's health, but it also affects their ability to perform their jobs effectively, which could negatively affect an employer's bottom line. A study examined how the presence of obesity affected the ability to complete three upper body work-related tasks. The study found that individuals with obesity had about 60 percent reduced endurance in completing the tasks compared to their counterparts with normal weight. Older participants were also tested, and older age had no impact on these tasks-only obesity did. Obesity also led to higher rates of strength loss, increased discomforts and declines in performance. Work demands may have to be altered to prevent the fatigue associated with obesity in workers.
