Feifei Wang and colleagues at the University of Michigan studied 23,500 workers at General Motors.

B; F They estimated that getting the most sedentary(惯于久坐的)obese workers to exercise would have saved about$790,000 a year.or about 15 percent of health—care costs for the whole group Company—wide,the potential savings could reach$7.1 million per year,they reposed in the Journal of Occupational and Environmental Medicine.

But adding two or more days of light exercise——at least 20 minutes of exercise or work hard enough to increase heart rate and breathing——lowered costs by on average$500 per employee a year,the researchers found.
