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.

A:According to Sarah Burgard, people’s health tend to get worse when they develop chronic diseases. B:they experience job insecurity. C:they see good job prospects. D:they have psychological problems.
