Wild weather, unexpected coral reefs and dangerous sea creatures… these are the nightmares (噩梦) you can imagine a teenager on a solo voyage (独自旅行) around the world might suffer from. But for Laura Dekker, sailing around the globe seems less a price to be paidthan a prize to be treasured.

    As the 19-year-old Dutch sailor said in Maidentrip, a documentary（纪录影片） released last year about her experience of becoming the youngest person to sail around the world alone in 2012, “I was born on a boat. I lived my first five years at sea. And ever since, all I have wanted is to return to that life.”

    With her yacht(游艇) Guppy, Dekker began her journey at 14 and sailed 50,004 kilometers in 519 days.

    The flying fish keeping her company, the dolphins following in her wake and the warm days spent on deck playing the flute (长笛) as she watched another unforgettable sunset were enough to make others jealous.

    But these didn't always go well. There were terrible moments in which Dekker feared death. On one occasion, a whale almost turned Guppy over. Another time, she battled extreme winds and Guppy surfed down 8-meter-high waves.

    Out on the open sea alone, she also got used to living without a fridge, a flushing（用水冲洗） toilet, and a hot shower.

   “As a human being you don't need much,”she told Stuff.co.nz. “ They might make life more comfortable, but you really don't need them to be happy.”

    In fact, her outlook on life was shaped by the trip. “I wanted the storms. I wanted the calms. I wanted to feel loneliness,”she told The New York Times. “And now I know all these things. It's the end ofthe dream I had as a child, and it's the beginning of my life as a sailor.”

    Some people think if you are happy, you are blind to reality. But when we research it, happiness actually raises every single business and educational outcome for the brain. How did we miss this? Why do we have these social misunderstandings about happiness? Because we assumed you were average. When we study people, scientists are often interested in what the average is.

    Many people think happiness is genetic. That's only half the story, because the average person does not fight their genes. When we stop studying the average and begin researching positive outliers —people who are above average for a positive aspect like optimism or intelligence —a wildly different picture appears. Our daily decisions and habits have a huge impact upon both our levels of happiness and success.

    Scientifically, happiness is a choice. It is a choice about where your single processor brain will devote its limited resources as you process the world. If you scan for the negative first, your brain really has no resources left over to see the things you are grateful for or the meaning embedded(嵌入) in your work. But if you scan the world for the positive, you start to acquire an amazing advantage.

    I wrote the cover story for the Harvard Business Review magazine on “Happiness Leads to Profits.” Based on my article called “Positive Intelligence” and my research in The Happiness Advantage, I summarized our researched conclusion: the single greatest advantage in the modern economy is a happy and busy workforce.

    A decade of research in the business world proves that happiness raises nearly every business and educational outcome: increasing sales by 37%, productivity by 31%, and accuracy on tasks by 19%, as well as a number of health and quality-of-life improvements.

Hobbies Help Cure Addiction to the Internet

    While some parents have expressed concerns about the amount of time their children spent surfing the Internet during the summer break from school, it wasn't a problem for Yin Qiming.

    Instead, the 37-year-old Shanghai resident and his daughter divided their vacation between cyberspace and the 8-year-old's other interests.

    “My daughter has many hobbies and I and her mother respect her choices, so we accompany her to classes she enjoys, such as learning to play the drums and drawing,” he said.

    “She loves to play outside with her friends, so she doesn't think the Internet is a must-have thing in her life.”

    Yin added that he rarely imposes a time limit on his daughter's online activity.

    “She sometimes uses WeChat (a popular instant-messaging tool) on my mobile phone, but only to contact her mother,” he said. “Once she has her own plans every day and realizes that the internet is just a part of life, she won't become addicted to it.”

    Li Lin, a primary school teacher from Liaoning province, expressed a similar opinion.

    “We do some homework online, including reciting stories, and the children use the Internet frequently every day of their lives,” she said, noting that the children's online activity is limited to 30 minutes a day at school.

    “We should make better use of the Internet to provide children with more knowledge and help them to grow up,” said Li, who has a 10-year-old son.

    The key to preventing children, especially those at primary and middle schools, from becoming addicted to the Internet is to limit the time they spend online and to ensure that they know cyberspace cannot replace traditional forms of communication, she said.

    Mao Feizhu, a psychologist from Fujian province in southeast China, said people overestimate the influence of the internet.

    “Many people, even some parents, believe the Internet plays a big role in our daily lives, and many things can be completed online, but that's not completely right,” she said.

    “We can use social applications to talk or play basketball games, and even share what we are thinking about, but sometimes it's impossible for our emotions to be accurately reflected in this way. What children need is emotional communication and real physical exercise. After all, love cannot be bought on the net,” she said.

    Perhaps, the best way to stop young netizens spending too much time online is to encourage their other interests but also accompany them when they go online: “We should use the Internet, not become its slaves.

    Researchers found that walking around with a forced smile and fake happiness simply leads to people feeling unhappier. So, putting a brave face on your sadness could be harmful. The research also found that women suffered more than men when pretending to be happy.

    Dr. Brent Scott, who led the study, said employers should take note because forcing workers to smile when dealing with the public can result in bad outcomes. He said, “Smiling for the sake of smiling can lead to emotional tiredness, and that's bad for the organization.” He also said the research showed customer-service workers who had “fake smiles” throughout the day didn't want to work, so their productivity dropped.

    The study is one of the first of its kind to examine emotional expressions over a period of time and compare the different effects on men and women. Dr. Scott's team examined the effects of “surface acting”, or fake smiling, compared to “deep acting”, or making people smile by thinking of pleasant memories.

    Dr. Scott said, “Women were harmed more by surface acting, meaning their moods worsened even more than men's. However, they were helped more by deep acting, which means their moods improved more by thinking of pleasant memories.”

    According to Dr. Scott women tend to suffer more when pretending to be happy because they are expected to be more emotionally expressive than men. Therefore, forcing a smile while feeling down is more likely to go against their normal behavior and cause more harmful feelings.

    Although deep acting can improve moods a little in the short term, Dr. Scott says it's not a long-term solution to feeling unhappy. There have been some suggestions that if you do this over a long period you start to feel unreal. You're trying to develop positive emotions, but at the end of the day you may not feel like yourself any more.

    Getting rid of dirt, in the opinion of most people, is a good thing. However, there is nothing fixed about attitudes to dirt.

    In the early 16^th century, people thought that dirt on the skin was a means to block out disease, as medical opinion had it that washing off dirt with hot water could open up the skin and let ills in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So did the king of England in 1546. Thus began a long time when the rich and the poor in Europe lived with dirt in a friendly way. Henry IV, King of France, was famously dirty. Upon learning that a nobleman had taken a bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.

    Though the belief in the merit of dirt was long-lived, dirt has no longer been regarded as a nice neighbor ever since the 18^th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War Ⅱ. Advertisements repeatedly sell the idea; clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?

    Attitudes to dirt still differ hugely nowadays. Many first-time parents nervously try to warn their children off touching dirt, which might be responsible for the spread of disease. On the contrary, Mary Ruebush, an American immunologist(免疫学家)，encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.

    Many doors close for those who have ever been in prison for a crime. It can be difficult for former prisoners to reenter society. A number of training programs are aimed at reopening doors for these men and women.

    "Together We Bake" teaches cooking and marketing skills to women who have spent time in prison so they can start new lives. It is a 10-week program which teaches women how to bake and sell cookies. Two friends, Tricia Sabatini and Stephanie Wright, created the program.

    "I have a background in social work and she is an amazing baker," Ms. Wright explains. "We discovered that for this population of women, returning from prison into the community, there aren't a lot of resources for them. So we thought we could combine our passions (激情) and develop this job as a training program. "Stephanie Wright says they started the program earlier this year." We had two classes so far that have graduated. This is our third class. We have eight women currently in this class. We've 16 women graduated in the first two classes."

    Terry Garred is one of the graduates. She says the program helped her turn her life around. Next she hopes to complete her high school studies. She is also working for "Together We Bake" to help other women follow the path she took.

    The program includes classes in which the women talk about their experiences and learn communication and job skills. Thirty-six-year-old Jamie White had spent three years in jail, which made her a little puzzled about her future life back into society. But she found those meeting were very helpful. She learned how to open up, and was just trying to better herself. She gained new skills. She sells baked goods at local markets every weekend now.
