翻译公司最新消息：法国研究人员于本周一称，与不吸烟者相比，中年吸烟者在记忆力和推理测试中的表现较差。这无疑是戒烟的又一个理由。

研究人员分析了之前收集的英国约五千名公务员的有关数据后发现，与从不吸烟者相比，吸烟者在记忆力、推理、词汇和口头表达等几项测试中表现居五组中最差的几率更大。

研究人员发现，吸烟会导致中年人智力水平下降，而且会导致日后老年痴呆及其它很多身体性疾病。

Middle-aged adults who smoke tended to perform poorly on tests of memory and reasoning compared to nonsmokers, adding to the list of reasons not to smoke, French researchers said on Monday.

Analyzing previously collected data on about 5,000 British civil servants, the researchers found those who smoked were more likely than people who never smoked to be in the lowest-performing of five groups in tests of memory, reasoning, vocabulary and verbal fluency.

Smoking was associated with mental decline in middle age, as it is with dementia and a host of physical ills later in life, they found.
