介绍:
How to Become a ‘Superager’
如何让你的大脑青春永驻
Think about the people in your life who are 65 or older. Some of them are experiencing the usual mental difficulties of old age, like forgetfulness or a dwindling attention span.
想一想你生活中的那些年龄不低于65岁的人吧。他们中的某些人正面临在老年群体中颇为常见的精神障碍，比如健忘或者注意力集中的时长变短。
Yet others somehow manage to remain mentally sharp. My father-in-law, a retired doctor, is 83 and he still edits books and runs several medical websites.
但其他一些人则以某种方式成功地保持了头脑的敏锐。我的公公是一名退休医生，现年83岁的他仍然在做图书编辑工作，并运营着几个医学网站。
Why do some older people remain mentally nimble while others decline?
为什么一些人老年时思维依旧敏捷，另一些人却每况愈下呢？
“Superagers” (a term coined by the neurologist Marsel Mesulam) are those whose memory and attention isn’t merely above average for their age, but is actually on par with healthy, active 25-year-olds.
“超级老人”（Superager，由神经学家马塞尔·梅苏拉姆[Marsel Mesulam] 造出来的一个词） 是指记忆力和专注力不仅超出老年人的平均水平，还与健康活跃的25岁年轻人不相上下者。
My colleagues and I at Massachusetts General Hospital recently studied superagers to understand what made them tick.
我和麻省总医院(Massachusetts General Hospital)的同事们最近对超级老人做了研究，以便弄懂他们何以有这样的表现。
Our lab used functional magnetic resonance imaging to scan and compare the brains of 17 superagers with those of other people of similar age.
我们的实验室使用功能性磁共振成像扫描并对比了17名超级老人和其同龄人的大脑。
We succeeded in identifying a set of brain regions that distinguished the two groups.
我们成功地确认了把两个群体区别开来的一组脑部区域。
These regions were thinner for regular agers, a result of age-related atrophy, but in superagers they were indistinguishable from those of young adults, seemingly untouched by the ravages of time.
年龄相关性萎缩会让普通老年人脑部的这些区域变得较薄，而超级老人脑部的这些区域与年轻的成年人别无二致，似乎没有受到时间的摧残。
If you want to keep your brain young, take up a challenging activity. Learn a foreign language. Take an online college course. Master a musical instrument. Work that brain. Make it a year to remember.
如果你想保持头脑年轻，投入到一件具有挑战性的事情中去吧。学一门外语。参加在线大学课程。熟练掌握一种乐器。让大脑动起来。让这一年成为值得铭记的一年。
