Having a sense of purpose may add years to your life, regardless of what the purpose is, research suggests.
Not only does it contribute to healthy aging, but it may also stave off early death, according to a study of 7,000 Americans.
The research, published in Psychological Science, applies across adult life, says a US-Canadian team.
It may be because purposeful people look after their health better and are physically fitter, they believe.
The study tracked the physical and mental health of more than 7,000 US adults aged 20 to 75 years.
Their purpose in life was assessed by the extent to which they agreed or disagreed with three statements:
Some people wander aimlessly through life, but I am not one of them. I live life one day at a time and don't really think about the future. I sometimes feel as if I've done all there is to do in life.
When followed up 14 years later, the researchers found purposeful people had outlived their counterparts, even when controlling for other factors such as negative mood.
Furthermore, the added years did not appear to depend on the person's age, or whether or not they had retired from work.
In other words, having a purpose in life appears to be good for you across the adult years, the researchers say.
Dr Patrick Hill, of the department of psychology at Carleton University in Canada, said the notion of living a life of purpose — setting large goals that direct your day-to-day activities — seemed to be protective on a number of fronts.
"In this study it is mortality, but other studies have shown people report better health," he told BBC News.
"There is clearly a benefit from feeling a sense of direction or feeling you have these goals directing your day-to-day life."

3.【答案】A。解析：出處推斷題。如果是一篇report(報告)或journal期刊，應該詳細地描述研究的假設、過程及結論，但是這篇文章對于研究只是進行了簡單地描述，故排除B和D;C. magazine指刊登各種文章、小說、詩歌、評議的雜志，但是此篇文章是跟科學內容相關的，故排除。再根據文章倒數第二段：he told BBC News. 可推斷出文章應來源于報紙，故A正確。
