No matter the article is true or not, I hope every can carefully read the article and improve your English reading and analytical skills.

美国肯塔基大学的研究人员发现，能讲两种语言可以抑制大脑衰老的速度，双语人士的大脑反应速度也比只会讲一种语言的人要更快一些。不过，研究人员指出，该研究发现只适用于那些从10岁起就开始使用第二语言的双语人士。

Speaking two languages can actually help offset（抵消，弥补） some effects of aging on the brain, a new study has found.

Researchers tested how long it took participants to switch from one cognitive task to another, something that's known to take longer for older adults, said lead researcher, Brian Gold, a neuroscientist at the University of Kentucky.

"It has big implications these days because our population is aging more and more," Gold said. "Seniors are living longer, and that's a good thing, but it's only a good thing to the extent that their brains are healthy."

Gold's team compared task-switching speeds for younger and older adults, knowing they would find slower speeds in the older population because of previous studies. However, they found that older adults who spoke two languages were able to switch mental gears faster than those who didn't.

But don't go out and buy Rosetta Stone just yet. The study only looked at life-long bilinguals（通两种语言的人）, defined in the study as people who had spoken a second language daily since they were at least 10 years old.

First, Gold and his team asked 30 people, who were either bilingual or monolingual, to look at a series of colored shapes and respond with the name of each shape by pushing a button. Then, they presented the participants with a similar series of colored shapes and asked them to respond with what colors the shapes were by pushing a button. Finally, researchers presented participants with a series of colored shapes, but they mixed prompts for either a shape or a color to test participants' task-switching times.

The bilingual people were able to respond faster to the shifting prompts.

Researchers then gathered 80 more people for a second experiment: 20 young bilinguals, 20 young monolinguals, 20 old bilinguals, and 20 old monolinguals. This time, researchers used MRI scans to monitor brain activity during the same shape- and color-identifying tasks. Gold and his team found that bilingual people were not only able to switch tasks faster - they had different brain activity than their monolingual peers.

"It allows a sort of window into how the brains of people who have different cognitive processing abilities and are processing the same stimuli in different ways," said Kristina Visscher, a neurobiologist at the University of Alabama School of Medicine who did not work on the study.

Visscher called bilingualism a "beautiful natural experiment," because people grow up speaking two languages, and studies have shown that they reap certain cognitive benefits from switching between languages and determining which to respond with based on what's going on around them. The University of Kentucky researchers took it a step further by using brain imaging, which she said was "exciting."

Gold said he grew up in Montreal, where he spoke French at school and English at home, prompting relatives to question whether his French language immersion（沉浸，专心） would somehow hinder his ability to learn English.

"Until very recently, learning a second language in childhood was thought of as dangerous," he said. "Actually, it's beneficial."

个人觉得是真的。

这个。。。那去检验一下广东地区的人们是不是大脑衰老的慢一点~粤语不是被列为一种语言而不是方言了嘛~

讲双语的本身大脑就厉害一点，
儿时就能双语的当然都很厉害，但是双语环境很容易导致幼儿语言障碍，所以很多教育中心都不推荐双语，

个人感觉一半一半吧

讲 双语 只能 启蒙智力 开发右脑！ 但是对于抗衰老没有很大的帮助，抗衰老关键在于生活快乐·，不是有一夜发白的典故吗？=====经济条件是一个因素但是不绝对，对于学习有兴趣，对于工作有兴趣，有一些无伤大雅的追求爱好， 才是树立了真正的快乐之源~~~如果一切只是为了赚钱而赚钱，那不是行尸走肉，如果喜欢大富翁的游戏倒也属于兴趣了 考了第一名又怎么样，胜了，败了，又怎么样，我们都知道，那只是个过程而已~

我觉得可以吧，讲双语转换两种不同的语言，大脑运动多，抑制大脑衰老

真的抑制啊。。。

平时粤语国语都讲，学英语之后经常挂嘴边，看动漫学了一些日语，但是我觉的我脑子还是跟团浆糊一样
