Urban swans might be born with a daredevil gene that makes them less fearful of humans, compared with their rural colleagues.

    A study has found swans living in cities tend to be bolder and it is at least partly determined by a gene called DRD4. Birds with this gene could therefore be better adapted to settling in more populated areas, while more timid（胆怯的）swans would escape to less inhabited regions.

    It could help to explain why swans in public parks and on urban rivers have a reputation for being so aggressive towards humans - they are simply not afraid of us.

    Biologists from some universities in Australia, tracked and collected blood samples from black swans living in two wetlands near cities. One group of swans lived in a recreational urban park, while the other occupied a waste-water processing site out of town. The two areas were less than 20 miles apart. Later, from 2011 through 2013, the researchers started systematically scaring the swans at both sites. The researchers approached the birds and calculated how close they could get before they flew away. As expected, they noticed that while rural swans started flying away if a human was closer than 119 meters, the scientists could come as close to urban swans as 39 meters before taking off.

    Analyses of the blood samples, in fact, showed that 83 per cent of the less cautious swans presented the same genetic DRD4 variation（变异)while rural swans have different genetic makeups resulting in more wariness(谨慎，小心）.

The researchers conclude that swans with the bold variation of the gene might choose to live in urban environments, as they tend to be less bothered by human presence.

    Why do some people live to be older than others? You know the standard explanations: keeping a moderate diet, engaging in regular exercise, etc. But what effect does your personality have on your longevity?Do some kinds of personalities lead to longer lives?A new study in the Journal of the American Geriatrics Society looked at this question by examining the personality characteristics of 246 children of people who had lived to be at least 100.

    The study shows that those living the longest are more outgoing,more active and less neurotic (神经质的) than other people.Long-living women are also more likely to be sympathetic and cooperative than women with a normal life span.These findings are in agreement with what you would expect from the evolutionary theory: those who like to make friends and help others can gather enough resources to make it through tough times.

    Interestingly, however, other characteristics that you might consider advantageous had no impact on whether study participants were likely to live longer.Those who were more self-disciplined,for instance,were no more likely to live to be very old.Also,being open to new ideas had no relationship to long life,which might explain all those bad-tempered old people who are fixed in their ways.

    Whether you can successfully change your personality as an adult is the subject of a longstanding psychological debate.But the new paper suggests that if you want long life,you should strive to be as outgoing as possible.

    Unfortunately, another recent study shows that your mother's personality may also help determine your longevity.That study looked at nearly 28,000 Norwegian mothers and found that those moms who were more anxious, depressed and angry were more likely to feed their kids unhealthy diets.Patterns of childhood eating can be hard to break when we're adults,which may mean that kids of depressed moms end up dying younger.

    Personality isn't destiny(命运),and everyone knows that individuals can learn to change.But both studies show that long life isn't just a matter of your physical health but of your mental health.

    A group of graduates, successful in their careers, got together to visit their old university professor. Conversation soon turned into complaints about stress in work and life.

Before offering his guests coffee, the professor went to the kitchen and returned with a large pot of coffee and a variety of cups—porcelain, plastic, glass, crystal, some plain looking and cheap, some exquisite and expensive—telling them to help themselves to the coffee.

    When all the students had a cup of coffee in hand, the professor said: "If you noticed, all the nice looking expensive cups were taken up, leaving behind the plain and cheap ones. While it is normal for you to want only the best for yourselves, that is the source of your problems and stress. Be assured that the cup itself adds no quality to the coffee. In most cases it is just more expensive and in some cases even hides what we drink. What all of you really wanted was coffee, not the cup, but you consciously went for the best cups. And then you began eyeing each other's cups.

    Now consider this: Life is the coffee; the jobs, money and position in society are the cups. They are just tools to hold and contain life, and the type of cup we have does not define, nor change the quality of life we live. Sometimes, by concentrating only on the cup, we fail to enjoy the coffee God has provided us."

    God brews the coffee, not the cups. Enjoy your coffee!

    "The happiest people don't have the best of everything. They just make the most of everything."

    Live simply. Love generously. Care deeply. Speak kindly. Leave the rest to God.

    This may be music to your ears.

    Researchers P Jason Rentfrow and Samuel Gosling gave 3, 500 people a personality quiz. Then they asked them to name their favourite kind of music. "We found that the musical styles people like are closely linked to their personalities," Gosling says.

    RAP/HIP－HOP

    Known for their quick speech, some rappers can say more than 700 syllables (音节)a minute! If you like rap/hip－hop, you are energetic(精力充沛的)and have a way with words. You put a fresh spin on things, whether it's new moves on the dance floor or your hip style.

    CLASSICAL

    In the 18th century, classical musicians were like rock stars. Beethoven and Mozart, for example, played to packed concert halls.  If you like classical, you are open to new ideas and like debating with friends. Creative and imaginative, you can easily spend many hours scrapbooking, writing or painting.

    COUNTRY

    Country music came from the folk songs of English, Scottish, and Irish settlers of the southeastern United States. If you like country, you express your opinions well, which makes you the ideal class president or team captain. Traditional and loyal, you enjoy spending time with your family.

    POP

    Pop music is designed to appeal to(吸引)almost everyone, and it does. Each year, the industry brings in about 30 billion dollars! If you like pop, you are attractive to your friends. You can make big things happen, like planning for a huge party or inspiring your team to victory.

    ROCK/ALTERNATIVE

    In the 1950s, rock music created a brand－new culture. Teenagers, for the first time, had an identity(身份)separate from adults and children.

    If you like rock/alternative, you are a risk－taker who never accepts no for an answer. You rise to any challenge, like doing very well in a big exam or in the school play.

    If these personality profiles don't match you, that's OK. These are just for fun.

China has set new rules limiting the amount of time children can play online games. The rules limit children to just three hours of online game playing a week. That is one hour between 8 p. m. and 9 p. m. on Friday, Saturday and Sunday most weeks. 

Li Zhanguo has two children aged 4 and 8. Even though they do not have smartphones, they enjoy playing online games. Like many other parents. Li is happy with new government rules. But experts say it is unclear if such policies can help prevent addiction to online games. Children might just get addicted to social media instead. In the end, experts say, parents should be the ones to set limits and support good practice. 

There has been a growing concern in China about gaming addiction among children. Government reports in 2018 found that about one in ten Chinese children were addicted to the Internet. The new rules are part of an effort to prevent young people from spending too much time on unhealthy entertainment. That includes what officials call the "irrational fan culture" 

Under the new rules, the responsibility for making sure children play only three hours a day as largely on Chinese gaming companies like Net Ease and Ten cent. Companies have set up real-name registration systems to prevent young users from going past game time limits. They have used facial recognition technology to check their identities. And they have also set up a program that permits people to report what is against the law. It is unclear what punishments gaming companies may face if they do not carry out the policies. And even if such policies are performed, it is also unclear whether they can prevent online addiction. 

A specialist treating Internet addiction expects about 20 percent of children will find ways to break the rules by borrowing accounts of their older relatives and find a way around facial recognition. In his opinion, short-video alps such as Douyin and Kuaishou are also very popular in China. They are not under the same restrictions as games.
