People in Their 90s are Getting Smarter, Newscientist, July 12th, 2013
人們在90幾歲后會越來越聰明，新科學家科技雜志，2013年7月12日
Ninety-somethings seem to be getting smarter.
90多歲的人似乎變得越來越聰明。
Today's oldest people are surviving longer, and thankfully appear to have sharper minds than the people reaching their 90s 10 years ago.
年長者如今能活的更久，值得慶幸的是，比起10年前的90多歲的人，這些年長者擁有更加敏銳的思想。
Kaare Christensen, head of the Danish Aging Research Center at the University of Southern Denmark, and colleagues found Danish people born in 1915 were about a third more likely to live to their 90s than those born in 1905, and were smarter too.
南丹麥大學丹麥老齡化研究中心的負責人卡雷·克里斯滕森和他的同事發現，在1915年出生能活到90多歲的丹麥人比出生于1905年的能活到90歲的人多出三分之一，同時也更加聰明。
During research, which spanned 12 years and involved more than 5 000 people, the team gave nonagenarians born in 1905 and 1915 a standard test called a "mini-mental state examination" ,and cognitive tests designed to pick up age-related changes.
該研究歷時12年，涉及5000余人，研究團隊給這些出生于1905年和1915年年齡在90歲以上的老人進行了一項標準測試，該測試被稱為“簡易精神狀態檢查”，同時也進行了認知能力測試，這些測試旨在獲得增齡性變化。
Not only did those born in 1915 do better at both sets of tests, more of them also scored top marks in the mini-mental state exam.
1915年出生的人不僅兩組測試結果更好，同時也有很多人在簡易精神狀態測試中拿到了最高分。
It's a landmark study, says Marcel Olde Rikkert at Radboud University Nijmegen Medical Centre in the Netherlands.
荷蘭奈梅亨大學醫學中心的馬塞爾·奧德·瑞科特說，這是一個具有里程碑意義的研究。
It is scientifically rigorous, it invited all over 90-year-olds in Denmark to participate, and it also overturns our ingrained views of old age, he also says.
與此同時它表示，這項研究在科學上是嚴謹的。研究邀請了丹麥幾乎所有超過90歲的人參與，它同時也顛覆了我們對年老者根深蒂固的看法。
Olde Rikkert adds that cognitive function can actually be a lot better than people would assume until a very high age.
奧德·瑞科特補充說，認知能力實際上在人們到達一定高齡時比想象中的要更好。
Tellingly, there was no difference in the physical test results between the two groups.
引人關注的是，兩組人的體能測試結果并無明顯差異。
The authors say this "suggests changes in the intellectual environment rather than in the physical environment are the basis for the improvement".Thank you.
作者說，這顯示出智力環境的改變是人們變聰明的基礎，而不是因為物質環境的改變。謝謝。
