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

Researchers tested how long it took participants to switch from one cognitive(认知的) 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.

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 activities faster than those didn’t . The study only looked at life-long bilinguals, defined in study as people who had spoken a second language daily since they were at least 10 years old.

Gold and his team asked 30 people, either bilingual or monolingual(只懂一种语言的人) , to have a series of tests. They found that bilingual people were not only able to switch tasks faster, they had different brain activity than their monolingual peers.

Kristina called bilingualism "a beautiful natural experiment”, because people grow up speaking two languages,and studies have shown that they get certain cognitive benefits from switching between languages and determining which to respond with based on what's going on around them.

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 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. "

The stories we share with one another are important. They show wisdom, and provide inspiration. They are important to our development. But sometimes people chose not to tell.

Consider the negative effects of not sharing a story in the news: People are wondering if public health officials are holding back too much information about the recent outbreak of Ebola.

There is a danger in holding back stories that ought to be told. Bobette Buster said it like this, “The fact is, history has shown us that stories not told an become like a dangerous genie(妖怪)left in a bottle. When they are finally uncorked, their power to destroy is set free.”

There are a number of reasons why we hide parts of our story: they often show our weaknesses or expose our disadvantages; they require courage and strength to share; and of course, there are some stories that should be kept secret—especially those that embarrass someone else.

Most of us have two selves: the one we display on the outside and the one we actually are on the inside. And the better we get at hiding the stories that show our true selves,the more damage we may be causing to ourselves and to others.

Honesty and openness is important: It proves we are trustworthy. It displays we are human. We are not perfect or better. It highlights the importance of hard work and personal development. Hard work may not allow us to overcome our disadvantages completely. But with hard wonk: we do not have to be restricted to our mistakes.

Does this mean we admit every weakness, every disadvantage, and every secret regret to everybody we meet? No, of course not. There is a time and a place and a certain level of relationship necessary for some stories to be told in all appropriate manners.
