Exercise Lowers Employers Health Costs
Companies can save millions in health-care costs simply by encouraging their employees to exercise a little bit，researchers reported on Friday．
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 al 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’s—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 Environmental Medicine．
Of the whole group of W0水ere。about 30 percent were of normal weight，45 percent were overweight(超重的)。and 25 percent were obese．Annual health cares costs averaged$2，200 for normal weight，$2，400 for the overweight，and$2。700 for obese employees。
But among Workers who did no exercise，health—care costs went up by at least$1 00 a year。and were$3，000 a year for obese employees who were sedentary．
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．

Happy Therapy(诊疗)
Norman Cousins was a businessman from the United States who often traveled around the world on business．He enjoyed his work and traveling．
Then，after returning to the United States from a busy and tiring trip to Russia，Mr．Cousins got sick．Because he had pushed his body to the limit of its strength on the trip，a chemical change began to take place inside him．The material between his bones became weak．
In less than one week after his return.he could not stand．Every move that he made was painful．He was not able to sleep at night．
The doctors told Mr．Cousins that they did not know how to cure his problems and he might never get over the illness．Mr．Cousins，however, refused to give up hope．
Mr．Cousins thought that unhappy thoughts were causing bad chemical changes in his body．He did not want to take medicine to cure himself．Instead，he felt that happy thoughts or laughter might cure his illness．
He began to experiment on himself while still in the hospital by watching funnily shows on television．Mr．Cousins quickly found that ten minutes of real laughter during the day gave him two hours of pain-free sleep at night．
Deciding that the doctors could not help him．Mr．Cousins left the hospital and checked into a hotel room where he could continue his experiments with laughter．For eight days，Mr．Cousins rested in the hotel room watching funny shows on television， reading funny books．and sleeping whenever he felt tired．Within three weeks，he felt well enough to take a vacation to Puerto Rico where he began running on the beach for exercise．
After a few months，Mr：Cousins returned to work．He had laughed himself back to health.
