2 . It is quite reasonable to blame traffic jams, the cost of gas and the great speed of modern life, but manners on the road are becoming horrible. Everybody knows that the nicest men would become fierce tigers behind the wheel. It is all right to have a tiger in a cage, but to have one in the driver’s seat is another matter.

Road politeness is not only good manners, but a good sense. It takes the most cool-headed drivers great patience to give up the desire to beat back when forced to face rude driving. On the other hand, a little politeness goes a long way towards reducing the possibility of quarrelling and fighting. A friendly nod or a wave of thanks in answer to an act of politeness helps to create an atmosphere of good will and becomes so necessary in modern traffic conditions. But such behaviors of politeness are by no means enough. Many drivers nowadays don’t even seem able to recognize politeness when they see it.

However, misplaced politeness can also be dangerous. A typical example is the driver who waves to a child crossing the street at a wrong place into the path of oncoming cars that may not be able to stop in time. The same goes for encouraging old ladies to cross the road wherever and whenever they want to.

An experienced driver, whose manners are faultless, told me it would help if drivers learnt to correctly join in traffic stream without causing total blockages that give rise to unpleasant feelings. Unfortunately, modern drivers can’t even learn to drive, let alone master the roadmanship (公路驾车技能). Years ago, experts warned us that the fast increase of the car ownership would demand more give-and-take from all road users. It is high time for all of us to take this message to heart.

3 . When given the choice, about 85% of people say they would not want to know about some negative event far in the future. Yet recently millions around the globe have downloaded FaceApp, which allows users to see how they might age in real life.

Many had fun with joking that they love the FaceApp old filter (滤镜). Beneath the humor is a serious subject: How do we learn to relate to our future selves? It’s important that we try to because it could help strengthen the long-term decisions that we make. However, we often fail to make sacrifices for the older versions of ourselves.

More than half of the respondents in a recent survey of 2, 800 Americans said they rarely or never thought about what their lives might be like 30 years from now. This isn’t surprising, since most of us are firmly rooted in the present and thinking about the distant future can seem like a distant priority. My ongoing research might also offer an explanation: We tend to think about our future selves as if they are someone different from who we are today. In an effort to narrow these empathy (共情) gaps, my research workmates and I have tried to humanize (使人性化) people’s future selves in the same way others have tried to humanize charity receivers. Given that a photograph of one hungry child can spark emotional reactions, and cause viewers to donate, we have provided participants with vivid images of their distant selves.

That seems helpful. In a recently completed project in Mexico, we found that exposure to future-self images led more people to add to their pensions (养老金). Despite this research, I’m not sure that the app users will suddenly increase their pension and care about their health. The silly app isn’t paired with an immediate opportunity to change any of these things.

The lesson from FaceApp shouldn’t be that we need to combine hi-tech visuals with savings for retirement. The lesson, then, leads to a question: What more can be done to urge us to think about, care for who we will one day become?

4 . There is a popular saying in the English language: “Sticks and stones may break my bones, but words will never hurt me.” Well, that is not true. Unkind words, name-calling or even the so-called “the silent treatment” can hurt children as much as being physically hit, sometimes even more so. A recent study of middle school children showed that verbal (言语的) abuse by other children can harm, the development in the brain. The study was a project of researchers at Harvard Medical School in Massachusetts. Researcher Martin Teicher and his team studied young adults, aged 18 to 25. These young men and women had not ever been treated in a cruel or violent way by their parents. The researchers asked the young people to rate their childhood exposure to verbal abuse from both parents and other children. Then the researchers performed imaging tests on the brains of the subjects.

The images showed that the people who reported suffering verbal abuse from peers in middle school had underdeveloped connections between the left and right side of the brain. The two sides of the brain are connected by a large bundle of connecting fibers called the corpus callosum. This was the area that was underdeveloped.

The middle school years are a time when these brain connections are developing. So, unkind, hurtful comments from children or adults during this period have the greatest effect. The researchers tested the mental and emotional condition of all the young people in the study. The tests showed that this same group of people had higher levels of fear, depression, anger and drug abuse than others in the study.

The researchers published their findings online on the American Journal of Psychiatry's website.

Parents cannot control what other people say to their children, but they can prepare their children.

5 . Is any economist so dull as to criticize Christmas? At first glance, the holiday season in western economies seems a treat for those concerned with such vagaries (奇想)as GDP growth. After all, everyone is spending; in America, retailers make 25% of their yearly sales and 60% of their profits between Thanksgiving and Christmas. Even so, economists find something to worry about in the nature of the purchases being made.

Much of the holiday spending is on gifts for others. At the simplest level, giving gifts involves the giver thinking of something that the recipient would like he tries to guess his or her preferences, as economists say - and then buying the gift and delivering it. Yet this guessing of preferences is not easy; indeed, it is often done badly. Every year, ties go unworn and books unread. And even if a gift is enjoyed, it may not be what the recipient would have bought if they had spent the money themselves.

Interested in this mismatch between wants and gifts, in 1993 Joel Waldfogel, then an economist at Yale University, sought estimate the difference in dollar terms. In a research, he asked students two questions at the end of a holiday season: first, estimate the total amount paid (by the givers) for all the holiday gifts you received; second, apart from the emotional value of the items, if you did not have them, how much would you be willing to pay to get them? His results were gloomy: on average, a gift was valued by the recipient well below the price paid by the giver.

In addition, recipients may hot know their own preferences very well. Some of the best gifts, after all, are unexpected items that you would never have thought of buying, but which turn out to be especially well picked. And preference can change. So by giving a jazz CD, for example, the giver may be encouraging the recipient to enjoy something that was ignored before. This, a desire to build skills, is possibly the hope held by many parents who ignore their children’s desires for video games and buy them books instead.

Finally, there are items that a recipient would like to receive but not purchase. If someone else buys them, however, they can be enjoyed guilt-free. This might explain the high volume of chocolate that changes over the holidays. Thus, the lesson for gift-givers is that you should try hard to guess the preference of each person on your list and then choose a gift that will have a high emotional value.

6 . “Preventing obesity and smoking can save lives, but it doesn’t save money,”reported researchers. “ It was a small surprise, for it is against the common belief,” said Pieter van Baal, who led the study. “But it makes sense. If you live longer, then your costs of the health system will be more.”

The researchers found that from age 20 to 56, fat people had the most expensive health costs. But on average, healthy people lived 84 years. Smokers lived about 77 years, and fat people about 80 years. Smokers and fat people tended to have more heart disease than healthy people. Therefore, in the long run, the thin and healthy group spent about $417,000, from age 20 on. Smokers spent about $ 326,000 and fat people $371,000.

“The result throws a bucket of cold water onto the idea, based on guesswork, that obesity is going to cost trillions of dollars,” said Patrick Basham, a professor of health politics. “If we’re going to worry about the future of obesity, we should stop worrying about its financial impact,” he said.

“The benefit of obesity prevention may not be seen immediately in terms of cost saving in tomorrow’s budget, but there are long-term gains,” said Baal. “These are often immeasurable when it comes to people living longer and healthier lives.” In the meanwhile, he said that governments should recognize that successful smoking and obesity prevention programs mean that people will have a higher chance of dying of something more expensive later in life.

“Lung cancer is a cheap disease to treat because people don’t survive very long. But if they are old enough to get Alzheimer’s(早年性痴呆症) one day, they may survive longer and cost more. We are not advising that governments stop trying to prevent obesity,” Baal said.” But they should do it for the right reasons.”

7 . Today different online exercise programs are challenging the concept of traditional fitness models. Gyms and health clubs are no longer limited to "the four walls". Digital extensions of traditional fitness are appearing, and to reach as many people as possible, the fitness industry is expanding its boundaries through virtual（虚拟的）fitness and accepting the latest scientific findings and technological advancements in health technology.

Exergames（运动游戏）are a combination of physical exercise and digital games. Now fun and fitness are combined in various digital gaming products, like Wii Fit Plus, Fitness Evolved, and Kinect Sports. What's more, health technology is often built using principles of neuroscience, a science focused on studying the brain. Fitness Evolved, for example, focuses on stress and how you react to different stressors. This program helps you feel less threatened by targeting your specific stressors and then adjusting based on your interaction with the app.

Now there are a lot of smart exergames, one of which is BunAlong. This online video platform combines the advantages of having a human instructor with the perks of practicing in the comfort of your own home. The platform lets users connect with whoever makes them feel most motivated-their favorite gym instructors, or friends who might be living on the opposite side of the country. A wide variety of programs are offered through the platform, as well as different effort levels, so everyone can find something that suits their level of fitness.

Another example is Zwift, an online multiplayer video game based on indoor cycling. It allows you to join an online cycling group that includes members from over 150 countries. BitGym is also a smart virtual fitness app. As you train, you're given beautiful virtual scenery to look at, complete with natural sounds and location-specific facts. For this app, all you need to do is place your smartphone or tablet on your sports machine.

8 . One form of social prejudice (偏见) against older people is the belief that they cannot understand or use modern technology. Activities like playing computer games, going on the Net and downloading MP3s are only for the youngsters. Isn’t it unfair that older people enjoying a computer game should be frowned upon (反对) by their children and grandchildren?

Nowadays older people have more control over their lives and they play a full part in society. Moreover, better health care has let more people in their sixties and seventies feeling fit and active after retirement. Mental activity, as well as physical exercise, can contribute to better health. Playing computer games is a very effective way of exercising the brain. So that’s why grey gamers are often seen now.

When personal computers were first introduced, most older people didn’t believe they would ever get familiar with them. Now computers have been around for a few generations and retired people have gradually become more relaxed about using them for fun. Gamers over 65 prefer playing puzzle games and card games. Kate Stevens, aged 72, says, “I find it very relaxing. It’s not very demanding, but you still need to concentrate.”

Another development that has favored “grey games” is a change in the type of video games available on the market. There’s a greater variety of games to choose from, including more intellectual and complex strategy and simulation (模拟) games. For example, Internet Chess and Train Simulator are among the most popular of these. Train Simulator is based on real — world rail activities. Players can choose from a variety of challengers, such as keeping to a strict timetable and using helper engines during a winter storm.

Some people argue that “grey gamers” simply don’t have the skills required for computer games, and that teenagers are better. This couldn’t be further from the truth. Most computer games require the kind of analytical thinking that improves with practice, which means that the “grey gamers” may well be far better than the young. In games where speed is the main consideration, older people would be at a disadvantage because they may have slower reaction. time. On the other hand, “grey gamers” have a preference for slower — paced, mind challenging games.

9 . According to a new US study, couples who expect their children to look after them in old age should hope they have daughters because daughters are twice as loving as sons generally.

The research by Angelina Grigoryeva, from Princeton University, found that, while women provide as much care for their elderly parents as they can manage, men do as little as they can get away with and often leave it to female family members.

Her analysis of the family networks of 26, 000 old Americans concluded that gender （性别）is one of the most important things that decide whether or not people will actively care for their elderly parents.

In a paper presented at the annual conference of the American Sociological Association in San Francisco, she concludes that simply having a sister makes men likely provide less care. Using data from the University of Michigan Health and Retirement Study, a study which has been recording those people over 50s for the last decade, she analyzed that women provide an average of 12. 3 hours a month of care for elderly parents while men offer only 5. 6 hours.

“Sons reduce their relative caregiving efforts when they have a sister, while daughters increase theirs when they have a brother.”

“This suggests that sons pass on parent caregiving responsibilities to their sisters.”

In the UK, the 2011 Census showed that there are now around 6.5 million people with caring responsibilities, a figure which has risen by a tenth in a decade.

But many are doing so at the risk of their health. The census showed that those who provide 50 hours or more of care a week while trying to hold down a fulltime job are three times more likely to be struggling with ill health than their working counterparts who are not carers.
