     It is really possible to be bored to death,scientists have found.Researchers say that

people who live a boring life are more likely to die young,and that those who experienced

"high levels" of boredom are at double risk (危险) of dying from heart disease or a stroke

than those who are satisfied with their life.

     Researchers studied the results of 7,524 people aged between 35 and 55 who were

interviewed between 1985 and 1988 about their levels of boredom.Of those 7,524 people

who were monitored (跟踪调查) over 25 years,those who said____________were nearly

40 percent more likely to have died by the end of the study than those who did not.

     The original survey found one in ten people had been bored within the past month,with

women more than twice as likely as men to suffer from boredom.Younger employees and

those with more boring jobs were also found to be more likely to suffer from boredom.

     Martin Shipley,who wrote the report,said,"People who are bored are more likely to turn to

unhealthy habits like drinking,smoking,taking drugs,and getting addicted to the Internet,which

can cut people's lifeexpectancy (寿命).It_is_important_that_people_who_have_dull_jobs

_find_outside_interests_to_keep_off_boredom,rather_than_turn_to_drinking_or_smoking."

     A scientist said those who are bored should try to be happier by thinking more about the

needs of others."From being all me,me,me,they should be thinking-what can I do for my

family,my friends,my colleagues,even my boss?" he said.
