研究证实：越聪明，越长寿

A survey of more than 2,000 people living in the UK has found that those with a higher IQ are more likely to live a longer life. Researchers analysed data from the Scottish Mental Surveys - in which almost every 11-year-old in Scotland was given the same IQ test on the same day in 1932 - and tracked the participants' lives up to when they passed away.

基于对2000多名英国居民的调查，研究结果显示：智商越高的人长寿的几率越大。研究者分析了来源于苏格兰心智调查的数据：1932年，几乎每个11岁的苏格兰儿童都在同一天接受了相同的智商测试，之后测试者将接受追踪调查，直至他们去世。

Even when factors such as economic status and employment level were accounted for, the smarter kids ended up living longer than those with lower IQs. These results correlate to several previous studies that have found a link between IQ and mortality when other factors were filtered out.

即使经济地位和就业水平等因素都被考虑在内，调查仍旧显示，智商高的孩子寿命更长。这些结果与先前的研究不谋而合，即在排除其它因素的条件下，智商与死亡率有一定的关联。

"Subjects who died before 1 January 1997 had a significantly lower mean IQ at age 11 years than subjects who were alive or untraced," says the report, published in the British Medical Journal. "Our data shows that high mental ability in late childhood reduces the chances of death up to age 76 years."
