Although his 1-year-old smart-phone still works perfectly, Li Jijia already feels the need to replace it.

    “There are many better ones available now. It's time to upgrade(更新）my phone.”

    Li's impatience is shared by many. Shortly after the season when new products are released（发布，发售）, many consumers feel the urge to upgrade their electronic equipment, even though the ones they have still work just fine.

    As consumers' minds are occupied by Apple's newly released products and debate whether the Google tablet is better than the new Amazon Kindle, it might be time to take a step back and ask: “Do we really need the latest upgrades?”

    According to Donald Norman, an American author, “planned obsolescence (淘汰）” is the trick behind the upgrading culture of today's consumer electronics industry.

    Electronics producers strategically release new upgrades periodically, both for hardware and software, so that customers on every level feel the need to buy the newest version.

“This is an old-time trick—they're not inventing anything new,” Norman said. “This is a wasteful system through which companies--many of them producing personal electronics-- release poor-quality products simply because they know that, in six months or a year, they'll put out a new one.”

    But the new psychology of consumers is part of this system, as Norman admitted, “We now want something new, something pretty, the next shiny thing.” In its most recent year, Apple's profit margin(利润) was more than 21 percent. At Hewlett-Packard, the world's biggest PC maker, it was only 7 percent.

    Apple's annual upgrades of its products create sales of millions of units as owners of one year's MacBook or iPhone line up to buy the newest version, even when the changes are slight.

    As to Li Jijia, the need for upgrading his smart-phone comes mainly from friends and classmates. When they are switching to the latest equipment, he worries about feeling left out.

    “Some games require better hardware to run,” said Li. “If you don't join in, you lose part of the connection to your friends.”

    The haunting paintings of Helene Schjerfbeck, on show in the final leg of a travelling tour that has already attracted thousands of visitors in Hamburg and the Hague, may come as a surprise to many. Few outside the Nordic(北欧的) world would recognize the works of this Finnish artist who died in 1946. More people should. The 120 works have at their core 20 self-portraits, half the number she painted in all. The first, dated 1880, is of a wide-eyed teenager eager to absorb everything. The last is a sighting of the artist's ghost-to-be.

    Prematurely gifted, Schjerfbeck was 11 when she entered the Finnish Art Society's drawing school. “The Wounded Warrior in the Snow”, a history painting, was bought by a private collector and won her a state travel grant when she was 17. Schjerfbeck studied in Paris, went on to Pont-Aven, Brittany, where she painted for a year, then to Tuscany, Cornwall and St Petersburg. During her 1887 visit to St Ives, Cornwall, Schjerfbeck painted “The Convalescent”. A child wrapped in a blanket sits supported up in a large wicker(柳条编制的) chair, toying with a sprig(小枝条). The picture won a bronze medal at the 1889 Paris World Fair and was bought by the Finnish Art Society. To a modern eye it seems almost sentimental(感伤的) and is made up for only by the somewhat astonished, sad expression on the child's face, which may have been inspired by Schjerfbeck's early experiences. At four, she fell down a flight of steps and never fully recovered.

    In 1890, Schjerfbeck settled in Finland. Teaching exhausted her, she did not like the works of other local painters, and she was further isolated when she took on the care of her mother. “If I allow myself the freedom to live an isolated life”, she wrote, “then it is because it has to be that way.” In 1902, Schjerfbeck and her mother settled in the small, industrial town of Hyvinkaa, 50 kilometres north of Helsinki. Isolation had one desired effect for it was there that Schjerfbeck became a modern painter. She produced still lives and landscapes but above all moody yet sharp portraits of her mother, local school girls, women workers in town.

    “I have always searched for the dense depths of the soul, which have not yet been discovered by humans themselves”, she wrote, “where everything is still unconscious -- there one can make the greatest discoveries.” She experimented with different kinds of underpainting, scraped and rubbed, made bright rosy red spots; doing whatever had to be done to capture the subconscious — her own and that of her models. In 1913, Schjerfbeck was rediscovered by an art dealer and journalist, Gosta Stenman. Once again she was a success.

    Researchers found that compared with young people who spent much of their free time in front of TV sets, those who were physically active often had higher self-respect, better grades and were less likely to have risky behavior like taking drugs, smoking, or drinking. The findings, based on a national survey of nearly 12, 000 middle and high school students, were published in a journal（期刊）.

    “Across the board, children who engaged in any kind of activity were better off than kids who watched a lot of TV,” said study co-author(合著者) professor Penny Gordon Larsen of the University of North Carolina.

    Other studies have linked certain content of television programs, such as violence and sex, to children's behavior. But beyond this issue, Gordon Larsen said that kids who spend hours watching TV” miss opportunities” to develop skills, learn teamwork and have other experiences that their more active peers(同辈) benefit(受益) from

    That doesn't mean, however, that kids have to be on the football team. The study found that some activities like skating and skateboard(滑板)——which adults sometimes frown upon——were also related to better self-respect and less risk-taking.

    That skaters were better behaved than TV-watchers might come as a surprise to some adults who consider these teens to be bad, according to Gordon Larsen. Skateboarding is forbidden in many public areas, and some communities(社区) disagree to build skating parks. But if kids who like to skate have nowhere to do it, “ it's a shame,” said Gordon Larsen.

    Not only should parents encourage their kids to engage（参与） in the physical activities they enjoy, she said, but schools and communities should also do more to create opportunities for children to be active.

    Sit down, close your eyes and relax. Think about your childhood and the memories you created. What was your favorite childhood memory and what was your favorite as a child? Or what your favorite Christmas present or your favorite candy bar when growing up? Answers may come easily for some people but for others, it may take more time to think about.

    Mary Jo McCarthy of Pequot Lakes wants to help others document their childhood memories which could be treasured by current families and for generations to come. McCarthy, 64, a short story author and retired columnist (专栏作家) for the Lake Country Echo weekly newspaper, began hosting a writing seminar (研讨班) titled "A Time to Remember". The closes are limited to 12 people and are conducted in the nursery at Lutheran Church of the Cross in Nisswa and the registration fee is $25.

    McCarthy said what led her to start the writing seminars was writing others' biographies(传记). A retired businessman asked her to write his biography as a ghost writer. She said others from her church in Pequot Lakes had also asked her to write their biographies because they didn't know how to write them. She thought hosting a class to help people write their own biographies would be more beneficial to them.

    McCarthy said people had busy lifestyles those days and didn't have a chance to sit down and write down their memories that they might forget and never remember. She said writing down the memories would document the person's life, so other family members, especially future generations would be able to read about them.

    For the past few months, my three-year-old daughter has spent an hour every week learning a foreign language. She walks into a small room in a local school, where she and a handful of three and four-year-old spend the next hour dancing to ^“La Vaca Lola”, a song about a Spanish cow, creating finger puppets(木偶) to voice what they like and don't like (me gusta, no me gusta) and shouting out which animals are big (grande) or small (pequeno).

    She tells us little about the classes. In fact, for the first few weeks, nothing at all. I begin to wonder if it was a huge mistake (each lesson works out at about £9) but then I show her “La Vaca Lola” on YouTube. She shouts vaca with enthusiasm and with what I hope is a Spanish accent.

    The wish to enroll(使……加入) her in language lessons came, like most things, gradually and then in a sudden rush. In my day job, I read and edit stories about the Chinese economy. For a long time, I felt that it would be good for her to learn another language but I had no great plan as to when.

    Then I read Edward Luce's The Retreat of Western Liberalism and all my thoughts and worry about the economy combined into a panic. Waking in a sweat, it seemed obvious that if my daughter was to have any kind of future, she would have to learn another language. Ideally (理想地) immediately.

    I thought about Mandarin Chinese, one of the top 10 languages most important for our future, according to the British Council (others include Arabic, French, German, Portuguese, Italian, Russian, Dutch and Japanese). But there were no classes for young children nearby. There were, however, local Spanish classes—the number-one language on the list. When she started to sing "Incy Wincy Spider" in Spanish and English—helped by a Spanish nursery worker-our decision was made.

"Don't get dirty!" was once often shouted by parents angrily watching their children ruin their best clothes. It was unavoidable that children's whites would turn brown before the day was over. 

Today, many parents may secretly wish their children had the chance to pick up a bit of dirt. With the rise of city life, and the attraction of video games and social media, contact with nature is much less than in the past. For many, there is simply no opportunity to get muddy. According to recent research, the dirt outside is teaming with friendly microorganisms (微生物) that can train the immune (免疫的) system and build the body against illnesses, such as anxiety. 

These findings show that outdoor exercise is not only beneficial because of the chance to run around free—but that certain natural materials, such as soil and mud, also have powerful microorganisms which have positive effect on children's health. Outdoor play can also offer valuable learning experiences. For example, the act of rubbing and shaping materials like mud or sand can help children develop their senses and movement. 

Such activities—away from the house or classroom—may also help children to find ways to deal with emotions that may be hard to explore in other environments. So-called "Sandtray Therapy (沙盘疗法)", which includes using sand to express one's thoughts and feelings, is an accepted form of guidance for children who are struggling to speak out their inner emotions. 

Surprisingly, people who spent most of their childhood in the countryside show a better reply to stressful events like public speaking compared with those who grew up in cities. "The people who grew up in cities are kind of ‘walking time bombs' when facing the stress we meet today. However, people who have spent lots of time in nature since childhood are generally stronger in recovery and more positive." says Christopher Lowry, a professor of University of Colorado Boulder.
