In the late 1950s, a Russian geneticist called Dmitry K. Belyaev attempted to create a tame (驯化的) fox population. Through the work of a breeding programme at the Institute of Cytology and Genetics at Novosibirsk, in Russia, he sought to find the evolutionary pathway of tame animals. His test subjects were silver-black foxes, a melanistic (带黑色的) version of the red fox that had been bred in farms for the color of their fur.

    He selected the animals based on how they responded when their cage was opened. About 10% of the foxes displayed a weak “wild-response”, meaning they were docile around humans. Those that hid in the corner or made aggressive voices were left in the farm. Of those friendly foxes, 100 females and 30 males were chosen as the first generations of parents.

    When the young foxes were born, the researchers hand-fed them. They also attempted to touch or pet the foxes when they were two to two-and-a-half months old, for strictly measured periods at a time. If the young foxes continued to show aggressive response, even after significant human contact, they were thrown away from the population—meaning they were made into fur coats. In each selection, less than 10% of tame individuals were used as parents of the next generation.

    By the fourth generation, the scientists started to see dramatic changes. The young foxes were beginning to behave more like dogs. They wagged their tails and “eagerly” sought contact with humans. By 2005-2006, almost all the foxes were playful, friendly and behaving like domestic dogs. The foxes could “read” human hints and respond correctly to gestures or glances.

    I was waiting for a phone call from my agent. He had left a message the night before, telling me that my show was to be cancelled. I called him several times, but each time his secretary told me that he was in a meeting and that he would call me later. So I waited and waited, but there was still no call. Three hours passing by, I became more and more impatient. I was certain that my agent didn't care about my work, and he didn't care about me. I was overcome with that thought. I started to shout at the phone, “Let me wait, will you? Who do you think you are?”

    At that time I didn't realize my wife was looking on. Without showing her surprise, she rushed in, seized the phone, tore off the wires, and shouted at the phone, “Yeah! Who do you think you are? Bad telephone! Bad telephone!” And she swept it into the wastebasket.

    I stood watching her, speechless. What on earth...?

She stepped to the doorway and shouted at the rest of the house, “Now hear this! All objects in this room—if you do anything to upset my husband, out you go!”

    Then she turned to me, kissed me and said calmly, “Honey, you just have to learn how to take control.” With that, she left the room.

    After watching a crazy woman rushing in and out, shouting at everything in sight , I noticed that something in my mood (情绪) had changed. I was laughing. How could I have trouble with that phone? Her anties helped me realize I had been driven crazy by small things. Twenty minutes later my agent did call. I was able to listen to him and talk to him calmly.

    Visitors to the grounds of New College at England's Oxford University pass under an iron gate with the advice: Manners make the man. Even after an appropriate update to: Manners make the person, it's thought-provoking(引人深思的)—especially to today's Americans.

    When we think about what makes the person—it's more likely the degree, the job, the salary. Since when do we count manners as a measure of success?

    We do know that these would make life nicer, if more tolerable. However, we forget or overlook our manners. So , it seems, does everyone else—including, unluckily, our children.

    As a university president, one of my great joys is to visit our campuses and see our students, though we're separated by different generations, interests, and, of course dressing, each student tells me something within the first few minutes that we meet: whether he or she has been taught manners. I sense this in different ways: through her words or her gestures, in the way she listens or how he refers to friends and faculty, how she greets and says goodbye, how he responds when an elderly person enters the room.

    In the absence of manners, however, I make some allowances. For instance, the many ethnic(种族的)groups that students represent often have different explanations of what makes up good manners. In other cases, some students may reject what they've learned to break from their parents and be accepted by other students. Whether students are being different or openly opposing, a recent experience I had with them tells me that there's some hope for reviving and good manners.

    Good manners don't just guarantee acceptance. Good manners open doors to deeper connections and more meaningful roles in our society. Good manners are gentle signals that show we care about one another and allow us to relate to another person in a thoughtful way but at a respectable distance.

    Webber is a labor economist. His latest research offers guidance on how to keep students on target to earn a degree from a college or university. Among his findings: It is important, whenever possible, for college students to complete their degree program in four years. Also, getting a part-time job is probably a good thing to help finance a college education. But too much time spent working on a job makes it less likely the student will graduate.

    One thing, Webber said, is financial aid that helps many students pay for college. Scholarships and other assistance generally stop after four years. So the cost of each additional year in school is likely to come almost entirely from the student and/or parents.

    But there are other reasons why taking more than four years is a problem, as Webber notes. It's because life gets in the way, other things happen. He means the longer you stay in college, the more likely that some unexpected event will affect your studies. It could be a loved one getting sick, a parent losing a job, or the student running out of money for college.

    Only about four in 10 graduated within four years. It is also important that students have enough time to complete their college classes, Webber added. His research suggests part-time work of 15 hours or less will not cause harm to the student's scholastic performance. But his research shows students who work 20 hours or more a week are about 15 percent less likely to graduate on time, or to graduate at all.

    His belief is that students active in college athletic programs would face the same problem. It is common, he said, for student athletes to spend 20 hours or more for training, travel and to compete against athletes or teams from other schools.

    After a morning hike in the Saneum HealingForest, 46-year-old firefighter Kang Byoung-wook has tea made from the bark of an elm tree, practices yoga (瑜伽), and makes a picture with dried flowers. He is one of 40 firefighters taking part in a three-day program, the aim of which is to offer "forest healing" (森林治愈); the firefighters all have posttraumatic stress disorder (创伤后应激障碍).

    Saneum is one of three official healing forests in South Korea. Soon there will be 34 more. South Koreans-many of whom suffer from work stress, digital addiction, and great academic pressure have accepted the medicalization of nature with great enthusiasm.

    There is increasing evidence that being outside in a pleasant natural environment is good for us. But how many of us get to enjoy nature regularly? Fewer and fewer, it seems. According to Lisa Nisbet, a psychology professor at Canada s Trent University, evidence for the benefits of nature is pouring in at a time when we are most disconnected from it.

    "We don't think of being outdoors as a way to increase happiness," says Nisbet. "We think other things will, like shopping or TV." But South Korea is starting to challenge this opinion.

    So what are some of the benefits of nature that Nisbet refers to? Being surrounded by nature has one obvious effect: It calms us and reduces our stress levels. This has been shown to lower blood pressure and heart rates.

    Another experiment conducted by psychologist Stephen Kaplan found that people who took a 50-minute walk in a park had better attention and short-term memory than those who took a walk along a city street.

    Perhaps what's more surprising is that nature may also make us more creative. David Strayer, a psychologist at the University of Utah, showed as much with a group of participants, who performed 50 percent better on creative problem-solving tasks after three days of wilderness backpacking.

    In fact, we may never know exactly what nature does to the brain. Something mysterious will always remain, and maybe that's as it should be.
