3 . Every festival has its own meaning. Labor Day, for example, celebrates the value of hard work. Thanksgiving is about showing thanks to people around you. And Valentines’ Day is a time when you express love to your loved ones. But somehow it now seems that all festivals we just care about one thing — shopping. And that can be a big problem.

“In a way, over-consumption (过度消费) is the mother of all our environmental problems,” Kalle Lasn once told CNN. Lasn is the organizer of Buy Nothing Day, a day set up in Canada in 1992 to fight against unhealthy spending habits, and has now become an international event. It’s held on the day, which is known as Black Friday — a famous shopping day in the US and Canada.

You can see the irony (讽刺) here.

Even though the idea of Buy Nothing Day was brought up 26 years ago, we seem to need it now more than ever. It’s just as Lasn said, all the different kinds of pollution in our lives today — bad air quality, the reduction of forest area, endangered animal species, and plastic bags found in the ocean — seem to be the same cause: over-consumption.

The latest example is the Singles’ Day shopping craze of Nov 11, which saw a new sales record. But as Nie Li, a campaigner at Greenpeace, told Reuters, “Record-setting over-consumption means record-setting waste.” And it was reported that last year the Singles’ Day packages left more than 160,000 tons of waste, including plastic and cardboard. The Collins Dictionary has also just named “single-use” its Word of the Year, pointing out the problem that there’re too many things we tow out after only using them once.

So, Buy Nothing Day might only be here for one day a year, but it’s not just to remind us to the a break from shopping on that day, but to change our lifestyle completely, focusing on fun “with people we care about” rather than wasting money on useless things.

5 . Among rich countries, people in the United States work the longest hours. They work much longer than in Europe. This difference is quite surprising because productivity per hour worked is the same in the United States as it is in France, Spain and Germany, and it is growing at a similar speed.

In most countries and at most times in history, as people have become richer they have chosen to work less. In other words they have decided to “spend” a part of their extra income on a fuller personal life. Over the last fifty years Europeans have continued this pattern, and hours of work have fallen sharply. But not in the United States. We do not fully know why this is. One reason may be greatly lower taxes in America, which increase the rewards to work. Another may be more satisfying work, or less satisfying personal lives.

Longer hours do of course increase the GDP (国内生产总值). So the United States has produced more per worker than, say, France. The United States also has more of its people at work, while in France many more mothers and older workers have decided to stay at home. The overall result is that American GDP per head is 40% higher than in France, even though productivity per hour worked is the same.

It is not clear which of the two situations is better. As we have seen, work has to be compared with other values like family life, which often get lost in interest. It is too early to explain the different trends in happiness over time in different countries. But it is a disappointing idea that in the United States happiness has made no progress since 1975, while it has risen in Europe. Could this have anything to do with trends in the work-life balance ?

6 . Kindness and kids just seem to go hand in hand. But 62% of more than 2, 600 participants in the NBC News State of Kindness Poll believe that today’s kids are less kind than those in the past. Women (66%) feel about this kindness fall more strongly than men (58%). Most of the participants who feel that way (77%) think parents caused the seeming lack of kindness among today’s children, with a few thinking that society, schools, or friends caused it.

At the same time, Americans say they don’t put kindness first when it comes to teaching kids values. Among all participants, honesty is taught more than kindness as well as other things like courage, leadership and strong work ethic (道德). But the younger generation--those aged 18-24-think highly of kindness rules. They choose kindness by 10% over honesty as the most important quality to teach kids.

The question of whether kindness is learned or taught—or somewhere in between-causes different opinions. According to the study, Americans have different opinions on whether kindness is something one is born with or needs to be learned and nurtured over time. Slightly more than half (52%) of the participants believe that all of us are born with the ability to show kindness, while 48% believe kindness must be developed.

Parenthood (父母身份) makes a difference to your thoughts on the causes of kindness Those without kids (56%) are more likely to think that people are born to be kind, while 50% of the participants with kids think kindness is developed.

Also, 51% of dads and 54% of men with no kids believe kindness is something one is born with. Slightly more than half of the moms say kindness must be learned, while 48% believe it is what one is born with.

7 . Teenagers who travel around the world alone have been making headlines quite often. A young person alone in a dangerous situation attracts attention and supporters. Young sailors also attract various views. For example, Jessica Watson was asked by the government to call off her solo trip across the ocean, yet the Prime Minister (总理) called her “a hero for young Australians” when she returned.   It seems views are poles apart on the ability and independence of young people.

Some experts tell us that teenage brains are likely to make wrong judgments. But such ideas often do not apply to specific individuals (个体) . Between the ages of 14 and 18, teenagers differ greatly in their abilities. The amount of independence that each is allowed should be determined not simply by their ages but by discussion with the related, responsible adults. Some teens are certainly inexperienced and make childish mistakes, but the ones who attempt dangerous journeys normally do so by winning the confidence of hard-headed and experienced adult supporters.

But it’s also wrong to think that any 16-year-old can make a hit as Jessica Watson. Watson calls herself “a common girl who had a dream”. Her purpose is to encourage teenagers but this idea can have the opposite effect of making them feel not good enough because great achievements are beyond them. Should all teens have such wild dreams? Actually, individuals face different conditions that limit their dreams.

Teenagers who travel around the world alone should not be judged by preconceived (先入为主的) views about young people. Nor should young “common” teenagers feel pressure to long for extraordinary personal goals. In fact, I believe the example of solo sailing overstresses what an individual can do. The teenage years are when most of us “common” people learn that we can achieve great things in cooperation with others.

10 . Some women say the voice in their head gets kinder as they enter midlife, while other women become more critical (挑剔的) of themselves. The difference in views appears to be related to the ability to accept age-related changes to their body, researchers have found.

In 2013, Professor Paxton, of the University of La Trobe’s Department of Psychology, was interviewed on ABC Melbourne about body image and well-being in women entering midlife. The ABC posted on their Facebook page the topic of the program and the question: Does the voice in your head get kinder as you get older?

The study found 56 percent of comments suggested the voice in women’s heads did get somewhat kinder with age. This view was associated with women accepting the age-related changes in their body as normal. “If they gained weight or they got wrinkles, it was a normal part of aging and they felt fine about it and it didn’t disturb their sense of self,” Professor Paxton said. “They were more likely to value health and well-being as opposed to appearance.”

On the other hand, 40 percent of comments suggested the voice did not get any kinder with age. This view was associated with women finding it difficult to accept being so different from the youthful ideal of women that is upheld in advertising and in the media. Women who expressed this view were concerned about how “invisible” they had become as a consequence. “They reacted negatively to the changes in their bodies as they aged and were very much aware that in our culture, youthful bodies are idealized,” Professor Paxton said.

Understanding why some women are preoccupied (心事重重的) with body image in midlife more than others is important given that having a bad body image can lead to physical and mental health problems, Professor Paxton said. These can include self-consciousness and anxiety, eating disorders, and an unwillingness to show oneself in public, which can reduce the amount women exercise or socialize. “They become unsociable and don’t fulfill their full potential. Those sorts of things can make a person very unhappy.”   

She said the insights from studies like this support the use of cognitive (认知的) behavioral therapy (治疗) designed to help women in midlife who have a preoccupation with body image to change negative thought patterns. This would involve discouraging them from comparing themselves to younger women, and encouraging acceptance of bodily changes related to age, and “self-care” behaviors that improve health and well-being.
