Have you ever considered why you begin yawning too when you see someone yawn? Or how hard it is to be among people laughing and not laugh yourself? Well, apparently it's because we have mirror neurons (神经元）in our brains.

    Put simply, the existence of mirror neurons suggests that every time we see someone else do something, our brains imitate it whether or not we actually perform the same action. This explains a great deal about how, we learn to smile, talk, walk, dance or play sports. But the idea goes further: mirror neurons not only appear to explain physical actions, they also tell us that there is a biological basis for the way we understand other people.

    Mirror neurons can undoubtedly be found all over our brains, but especially in the areas which relate to our ability to use languages, and to understand how other people feel. Researchers have found that mirror neurons relate strongly to language. A group of researchers discovered that if they gave people sentences to listen to ( for example: “The hand took hold of the ball” ) , the same mirror neurons were triggered as when the action was actually performed (in this example, actually taking hold of a ball).

    Any problems with mirror neurons may well result in problems with behavior. Much research suggests that people with social and behavioral problems have mirror neurons which are not fully functioning. However, it is not yet known exactly how these discoveries might help find treatments for social disorders.

    Research into mirror neurons seems to provide us with even more information regarding how humans behave and interact. Indeed, it may turn out to be the equivalent (相等物）for neuroscience of what Einstein's theory of relativity was for physics. And the next time you feel the urge to cough in the cinema when someone else does — well, perhaps you'll understand why.

    Is there a magic cutoff period when offspring become accountable for their own actions? Is there a wonderful moment when parents can become spectators (旁观者) in the lives of their children and shrug, "It' s their life," and feel nothing?

    When I was in my twenties, I stood in a hospital corridor waiting for doctors to put a few stitches in my son's head. I was asked, "When do you stop worrying?" A nurse said, "When they get out of the accident stage." My mother just smiled faintly and said nothing.

    When I was in my thirties, I sat on a little chair in a classroom and heard how one of my children talked incessantly, disrupted (打断) the class, and was headed for a career making license plates. As if to read my mind, a teacher said, "Don't worry. They all go through this stage, and then you can sit back, relax, and enjoy them." My mother listened and said nothing.

    When I was in my forties, I spent a lifetime waiting for the phone to ring and the cars to come home, the front door to open.

    My friends said that when my kids got married I could stop worrying and lead my own life. I wanted to believe that, but I was haunted by my mother' s wan ( 淡淡的 ) smile and her occasional words, "You look pale. Are you all right? Call me the minute you get home."

    Can it be that parents are sentenced to a lifetime of worry? Is concern for one another handed down like a torch to blaze the trail of human frailties and the fears of the unknown? Is concern a curse? Or is it a virtue that elevates us to the highest form of life?

    One of my children became quite irritable recently, saying to me, "Where were you? I've been calling for three days, and no one answered. I was worried!!!"

    I smiled a wan smile.

We thought we had it all—a beautiful house, three healthy children and one more on the way, two cars — and we loved it. We spent money like it was going out of style. Then, the market turned and my husband's job as a bigwig(大人物) at a construction company was gone. The company was closing down for ever.

    We both started looking for jobs right away, but there weren't any to be found. With each passing day our panic increased and we continued to work together in order to pull our family through. The more we pulled together, the closer we got. I felt feelings of great love for my husband that I hadn't felt in years.①

    That's why it was so hard for me to watch him blame himself for our present situation. I knew that he had no control over the economy, however, he constantly degraded (降低…身份)himself and his spirit sunk lower with each unkind comment. I continually asked him to stop, but he seemed to want to punish himself for not having a job.②

    Finally one afternoon I pulled him aside and said, “We have four healthy children. That's what's important. That makes you a rich man.”

    “But what if we lose the house? They'll hate me—you'll hate me.” he replied.

    I smiled at him and put my hands on both sides of his face to make him look me in the eye.③

    “If we live in a cardboard box on the empty place across the street I will be happy—as long as I have you.” I smiled again as I realized that I wasn't saying it. Somehow, in all the struggling together I had found that deep love for him that I had on the day we said “I do.”

    I could see relief wash through him as his shoulders and neck relaxed and the tension left his body. He held me close and we were able to talk and plan and dream together in a way that we hadn't in quite some time. ④

    We are still struggling financially, but I consider us well-off because we have something that money can't buy and no one can take away from us.

    The American state of Colorado is considering a ban on smartphones for children younger than 13.

    A Denver-based doctor - and father - is leading the effort. Tim Farnum is the founder of a group called ‘Parents Against Underage Smartphones.' His proposal would ban sales of smartphones to children under the age of 13. It would also ban sales to anyone who wishes to buy such a device for anyone younger than 13. The measure would also require sellers of smartphones to provide proof to the state government that they have asked buyers if the phone is for anyone under 13.

    The measure now needs about 300,000 signatures in order to appear on Colorado's statewide ballot (投票权)next year. If it makes the ballot and is approved by voters, Colorado would become the first state to have such a ban.

    Tim Farnum said he decided to push for the measure after watching his own children struggle with the mental effects of always having a smartphone around. "They would get the phones and lock themselves in the room and change who they were," he told The Coloradoan newspaper.

    State Senator John Kefalas, a Democrat, said he understands the reasoning behind the proposed law. However, he told The Coloradoan that a child's smartphone usage is a "family matter" and not something the government should decide. "Ultimately, this comes down to parenting,” he said, “making sure their kids are not putting themselves at risk.”

    Last year, the AAP (the American Academy of Pediatrics) released guidelines for media use by children. The group advised parents to limit time spent watching videos to no more than one hour a day of high-quality programming until age 6. After that, it said, parents should set reasonable time limits for their children and make sure electronic devices do not take time away from sleep or exercise.

    Nowadays women appear to have a positive image of themselves as safer drivers than men.

    In a survey done for insurer MetLife, 51% of women said they drive more safely. The evidence is on their side: Men are 3.4 times more likely than women to get a ticket for careless driving and 3.1 times as likely to be punished for drunk driving. "Women are on average less aggressive and more law abiding (守法的) drivers, which leads to fewer accidents," the report says. However, not all male drivers share the same opinion. Of the men surveyed by MetLife, 39% claimed male drivers were safer. The findings did back them upon one point: automotive knowledge. The report showed that more men are familiar with current safety equipment such as electronic stability control, which helps prevent rollover accidents.

    Auto safety unavoidably matters to Money. Insurance companies focus on what classes of drivers have the lowest dollar amounts of claims, and for now, that mainly includes women. In general, women pay about 9% less for auto insurance than men. A study by the website also showed that auto insurance rates are lower for women in most states. Among individual states, women get the greatest, advantage in Wyoming (where they pay 20% less), South Dakota and Washington, D. C, where their insurance costs are 16% lower.

    "More than 11,900 male drivers died in US traffic accidents in 2009, compared with just under 4,900 women drivers" according to the study. "Based on miles traveled, men died at a rate of 2. 5 deaths per 100 million miles traveled, vs. 1.7 deaths for women."
