They said obese (肥胖的) employees had higher health-care costs, but lowered those expenses by exercising just a couple of times a week -- without even losing any weight. Feifei Wang and colleagues at the University of Michigan studied 23,500 workers at General Motors. 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 1.5 percent of health-care costs for the whole group. Company-wide, the potential savings could reach $7.1 million per year, they reported in the Journal of Occupational and Environ A. Seventy percent. B. Thirty percent. C. Forty-five percent. D.
