And what you do eat, you don’t burn off - assuming you’re like the 40% of US who get no exercise. Most troubling of all, if you’re like any parent of any child anywhere in the world, you may be passing your health habits to your children, which explains why experts fear that this generation of American kids may be the first ever to have a shorter life span than their parents do.

While NICE’s decisions have angered some doctors and patient groups -particularly some oncologists (肿瘤科医生) who say they are unable to prescribe expensive, life- extending cancer drugs- mainstream politicians, the media and most Britons accept NICE’s rare rejections as a necessary compromise to keep universal coverage affordable in the face of rising health -care costs. As NICE chairman Sir Michael Rawlins recently told TIME, All health -care systems have implicitly, if not explicitly, adopted some form of cost control. In the U. S. , you do it by not providing health care to some people. That’s a rather brutal way of doing it. NICE’s decisions hear the loudest voice of disapproval from
A. some oncologists.

B. mainstream politicians.
C. the media.

D. most Britons.

Your health can suffer simply from fear of losing your job, says Sarah Burgard, a sociologist at the University of Michigan. After crunching data from two large national surveys, she concluded that chronic job insecurity over a two--year period rivals the anxiety of a job loss or a major illness. Burgard adjusted her data for what psychologists call neuroticism and found that even people who aren’t typically worriers report worse health when they believe their jobs are in danger. Fears of poor job prospects may have similar consequences. When Swedish researchers asked 21 - year - olds about their health during a recession, they reported more problems than a comparison group during a boom.
According to Sarah Burgard, people’s health tend to get worse whenA. they develop chronic diseases.
B. they experience job insecurity.
C. they see good job prospects.
D. they have psychological problems.
