When I was watching a sports event yesterday, I met with an amazing sight. It was not a gold medal, or a world record broken, but a show of pure courage and determination.

    The event was swimming. I watched a man dive off the blocks and knew right away that something was wrong. I'm not an expert swimmer, but I can tell a good dive from a poor one, and this was not exactly medal quality. When he resurfaced, it was evident that the man was not out for gold — his arms were waving in an attempt at freestyle.

    I heard the crowd begin to laugh at this poor man who was clearly having a hard time. Finally he made his turn to start back. It was pitiful. He made a few desperate strokes (划水) and you could tell he was worn out. But in those few awkward strokes, the crowd changed. No longer were they laughing, but beginning to cheer. Some even began to stand and yell things like, "Come on, you can do it!" He did. The crowd went wild.

    Just a short year ago, he had never even swum, let alone race. His country had been invited to take part in the event. Even though he recorded the slowest time, this man gave more heart than any of the other competitors—a man that gave his all, knowing that he had no chance but to compete because of the spirit of the games.

    One night about nine o'clock, Dr. Eyck, a surgeon, had a phone call from Dr. Haydon at the hospital in Clens Falls. The surgeon was asked to go there at once to operate on a very sick boy who shot himself while playing with a gun.

    The doctor was soon on his way to Clens Falls. It was 60 miles away. And it was snowing heavily in the city. The surgeon thought he could get there before 12 o'clock.

    A few minutes later, the doctor was stopped by a man in an old black coat. Gun in hand, the man ordered the doctor to get out. Then the man drove the car down the road, leaving the doctor in the falling snow.

    It was after 2 o'clock in the morning when the doctor arrived at the hospital in Clens Falls. Dr. Haydon told him that the boy had died an hour before. The two doctors walked by the door of the hospital waiting room. There sat the man in the old black coat with his head in his hands“Mr. Cuninghan,”said Dr. Haydon to the man, “This is Dr. Eyck. He is the surgeon who walked all the way from Albany to save your boy.”

    As free as they make us, mobile phones still need to stay close to a power source. Soon that may change with "green" power.

    Three Chilean students got the idea for a plant-powered device(装置) to charge their cellphones, while sitting in their school's outdoor courtyard during a break from exams, with dead mobile phones. Then, one of them had an "aha" moment.

    “It occurred to Camila to say about plants,” said inventor Evelyn Aravena. “'Why don't you have a socket, if there are so many plants? 'After that, we thought, 'why don't they have a charging outlet? Because there are so many plants and living things that have the potential to produce energy, why not?'”

    Their invention—a small biological circuit called E-Kaia—uses the energy plants to produce during photosynthesis(光合作用). A plant uses only a small part of that energy and the rest goes into the soil, and that's where the E-Kaia collects it. The device plugs into the ground and then into your phone.

    "It's the most amazing project I've ever seen in my life, plain and simple. They brought this original model, and it worked — and that's when it all changed, at least from my personal point of view and I began to support them." said Mauricio Cifuentes.

    The device solved two problems for the engineering students — they needed an idea for a class project, and an outlet to plug in their phones.

    "Looking for a place to charge the notebook, which had no power, and the mobile phones, we weren't able to find anything because all the other students were in the same state of madness trying to find a place to charge their devices," said Aravena.

    But plants are everywhere, and the bio－circuit makes the best of their excess(过多的) power.

    The E-Kaia doesn't carry much charge but it's powerful enough to completely recharge a mobile phone in less than two hours.

    The student inventors have applied for patents on their technology, and expect the E-Kaia to go on sale in December 2016.

    The obsession(痴迷) with perfection among young people has risen by more than 30 percent over the last three decades, a study has found.

    Many of them believe that their environment is extremely demanding and that others judge them strictly, according to analysis of data from more than 40，000 British, Canadian and American university students from 1989 to 2017.

    The research, carried out by the University of Bath and York St John University, found that the degree to which young people attach an unreasonable importance to being perfect, hold unrealistic expectations of themselves and are highly self­critical has increased by 10 percent when compared to previous generations. The authors suggested their findings point to the influence of three decades of neoliberalism(新自由主义) forcing young people to compete against one another.

    Lead author Dr Thomas Curran from the University of Bath's Department for Health said he hoped organisations responsible for safeguarding the welfare of young people, such as schools, universities, and policymakers who shape the environments in which these organisations operate, would “resist the promotion of competitiveness at the expense of young people's psychological health”.

    He said, “Rising rates of perfectionism highlighted in this study is in line with three decades of neoliberalism, which has forced young people to compete against each other within increasingly demanding social and economic aspects.”

    The researches defined perfectionism as a combination of extremely high personal standards and overly strict self­criticism, leading to psychological difficulties.

    Co­author Dr Andrew Hill of York St John University added, “The increase in mental health difficulties among young people makes for a convincing background for our findings. The higher level of perfectionism may be a key contributing aspect to such difficulties. Young people are trying to find ways to deal with increasing demands being placed on them and they are responding by becoming more perfectionistic towards themselves and others.”

WISH YOU WERE MORE CREATIVE?

    I want to ask you a favor. I have a pair of pants. Tell me: How many different ways can I put a pair of pants to use? Now imagine you're an architect. Same question. Now imagine you're Bill Gates. A scuba diver. A medieval knight. You still have the pants. What alternative uses come to mind?

    What you just practiced--the conscious act of "wearing" another self-is an exercise that, according to psychiatrist SriniPillay, MD, is essential to being creative.

    One great irony (讽刺) about our collective addiction to creativity is that we tend to frame it in uncreative ways. That is to say, most of us marry creativity to our concept of self: Either we're "creative" or we aren't, without much of a middle ground. "I'm just not a creative person!" a discouraged student might say in art class, while another might blame her talent at painting for her difficulties in math, making a comment "I'm very right-brained."

    Dr.Pillay, an assistant professor at Harvard University, has spent years overturning these ideas. He believes that the key to unlocking your creative potential is to challenge the stereotyped (陈词滥调的) advice that urges you to "believe in yourself." In fact, you should do the opposite: Believe you are someone else.

    He points to a study showing the impact of stereotype on one's behavior. The authors, psychologists Denis Dumas and Kevin Dunbar, divided their college student subjects into two groups, instructing one group to think of themselves as "eccentric poets" and the other to imagine they were "rigid librarians". The researchers then presented them all with ordinary objects, including a fork, a carrot, and a pair of pants, and asked them to come up with as many different uses as possible for each one. The former group came up with the widest range of ideas, whereas the latter had the fewest.

    These results suggest that creativity is not an individual characteristic but a "product of context and perspective". Everyone can be creative, as long as he or she feels like a creative person.

    Dr. Pillay's work takes this a step further: He argues that simply identifying yourself as creative is less powerful than taking the brave, creative step of imagining you are somebody else. This exercise, which he calls psychological Halloweenism, refers to the conscious action of "wearing" another self. An actor may employ this technique to get into character, but anyone can use it. According to Dr. Pillay, it works because it is an act of conscious unfocus, a collection of brain regions that spring into action when you're not focused on a specific task or thought. Most people spend nearly half of their days in a state of "unfocus." This doesn't make us lazy; it makes us human.

    Imagining yourself in a new situation, or an entirely new identity, never felt so productive. You're making yourself more creative, and you're giving yourself permission to do something you'd otherwise feel guilty about.
