"Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid."—Albert Einstein

If you have a kid with special needs in the school system, chances are you have come across that saying hanging on a classroom wall. My five-year-old daughter Syona has cerebral palsy (a medical condition affecting someone's control over their movement ) and it means, combined with her communication challenges and sight problems, that standard assessments (and by "standard", I mean the ones used to assess kids with special needs ) aren't always an accurate measure of her abilities.

By now you have probably heard about Chris Ulmer, the 26-year-old teacher in Jacksonville, Florida, who starts his special education class by calling up each student individually to give them much admiration and a high-five (a gesture of greeting or congratulation). I couldn't help but be reminded of Syona's teacher and how she supports each kid in a very similar way. Ulmer recently shared a video of his teaching experience. "I have seen their confidence and self-worth increase rapidly, " he said. All I could think was: How lucky these students are to have such inspirational teachers.

    Syona's teacher has an attitude that can best be summarized in one word: awesome. Her teacher doesn't focus on what can't be done—she focuses on what can be done. Over the past several months, my husband Dilip and I have seen Syona's confidence increase tenfold. She uses words she wouldn't have thought of using before. She recently told me about her classmate's trip to Ecuador and was very proud when I understood her on the first try.

    I actually wonder what the influence would be if we did something similar to what Ulmer does with his students in our home. We've recently started our day by reminding each other of the good qualities we all possess. If we are reminded of our strengths on a regular basis, we will become increasingly confident about progress and success.

    Ulmer's reach as a teacher goes far beyond the walls of his classroom. In fact, he teaches all of us to take a moment and truly appreciate the strengths of an important person in our lives.

    It's common knowledge that there are many benefits to being fit, but one large new study found that skipping out on the gym is practically the worst thing you can do for your health. In fact, the study claims not exercising might be more harmful to your health than smoking.

    New findings, published Friday in the journal JAMA Network Open, detail how researchers at the Cleveland Clinic studied 122,007 patients from 1991 to 2014, putting them under treadmill (跑步机) testing and later recording death rates. Researchers found a clear connection between a longer, healthier life and high levels of exercise. The report calls for health care professionals to encourage patients to achieve and continue a strong and healthy fitness routine.

    Although it is widely understood that an active lifestyle can lead to a healthy life, the study concludes that a lifestyle which involves much sitting but little activity is equal to having a major disease and the simplest cure is exercise.

    Dr Wael Jaber, co-author of the study, called the results totally surprising. “Being unfit on a treadmill or in an exercise stress test has a worse prognosis (病情预断), as far as death, than being a smoker or suffering from high blood pressure,” Jaber told CNN. “We've never seen something as noticeable as this and as objective as this.”

    The study also took a look at the risk of being overactive and found that extreme exercisers do not face higher risk of death: the research found that the more a person exercises the lower their death rates.

    There's a word of wellness I've loved for years. It's HALT: the idea that if you want to be calm and content, never let yourself get too hungry, angry, lonely or tired. Researchers are increasingly looking more closely at the "L" in "HALT", with one report presented to the American Psychological Association finding that long-term loneliness might be a greater public health risk than obesity.

    Loneliness is a problem with many faces. Some people are alone most of the time—data collected by the United Kingdom found that 200, 000 people over the age of 75 had not had a conversation with a friend or a relative in more than a month. But some people feel lonely even in a crowded room, disconnected from meaningful relationships even though their days are filled with people.

    To me, walking a positive path means walking alongside others—people who lift our spirits, share our values, challenge us to grow and learn and bring us joy. But social satisfaction doesn't come automatically or even easily to too many people. And in our age of individualized electronic devices, social media and text-based communication, it can be harder than ever to feel truly connected to others.

    I was so heartened to read that recently the British Parliament (议会) has created a "Minister for Loneliness" position to promote research, education and principles so as to cure what some researchers call "the loneliness disease". More and more doctors in America are also screening adult patients for loneliness at annual physical examinations, which is another promising sign.

    With proper social support and community participation, loneliness can be prevented from happening. If you are feeling lonely, make a list of your daily routines and ask yourself how you could add more social interactions to each day. Try reaching out for volunteer opportunities, clubs and organizations to join and old friendships to renew. If you are struggling, ask a consultant to help you identify your social obstacles and overcome them.

    For many students who desire to move around but not far freely, one of the most common vehicles is the bicycle. For such a seemingly simple invention, its story is not that simple.

    Most historians trace its origin back to 1817, when a German nobleman named Karl von Drais invented a wooden, two­wheeled machine that riders moved forward with their feet. His invention became popular in both England and France, where it eventually became known as the velocipede. Unfortunately, it was eventually banned as a danger to pedestrians and was rarely seen after the early 1820s.

    Things were quiet for several decades until the bicycle development took off in the 1860s. An important milestone happened in Paris in 1863 when pedals were added to the front axle (轴). This occurred in Pierre Michaux's workshop, but it's unclear whether he or his employee, Pierre Lallement, should be given credit for the innovation Lallement moved to the United States, where he obtained a patent for "improvements in velocipedes" in 1866. These new machines proved to be popular, and the name "bicycle" had come into use by 1869. However, many people referred to them as "bone shakers", which described their clunky ride due to a heavy wooden frame and steel wheels.

    In the 1870s, "high wheelers" or "penny­farthings" became popular. However, with a large front wheel and a much smaller rear wheel, they could be dangerous, if riders had to stop suddenly, as they would "take a header" when their momentum (动量) carried them over the front wheel onto their heads. Eventually, English inventor John Kemp Starley designed a "safety bicycle" with two same small wheels, a chain drive, and a set of gears. With tires added in and brake systems bettered in the following decades, bicycle production had skyrocketed to over one million bicycles by 1899.

    Mass production of bicycles increased their popularity greatly, since they became affordable for the average person. Over the course of the 20th century, manufacturers continued to improve the features and design of bicycles as new technologies appeared.

When looking at fashion shows or the latest magazine trends, you might think you've seen it all before. It seems that designers often revisit past concepts （概念）. However, to glimpse the future of fashion, one must turn to the meeting point of fashion and technology, where innovative ideas are born.

For several years now, people have been talking about "wearable technology" as the next big development. You can already buy watches that do everything your smartphone can do, or glasses with computers that follow your eye movements and feed information to you as you walk around. But there's much more to wearable technology than that.

Sports clothing is one of the areas. Runners already wear small computers on their wrists（手腕） that give them continuous information about how fast they're running, how hard their bodies are working, and so on. Experts agree that it's often sportspeople （usually young men） who are the first to take up new fashion ideas. Others then follow.

Women, it seems, are usually more interested in what clothes look like than what they can do, and technology has a part to play here too. Designers are making clothes that can change color with how you feel, or react to sound. And if you think that sounds unlikely, just think of all the things we accept as quite normal today that seemed impossible or silly only ten years ago.

The primary reason such items aren't available in mainstream stores is their high cost. However, like all technological products, their prices are likely to decrease rapidly, as technological clothing doesn't necessarily have to be costly.

Pick up any packaged processed food, and there's a decent chance that one of its listed ingredients will be "natural flavour". The ingredient sounds good, particularly in contrast to "artificial flavours" since there is a common belief that ingredients from nature are necessarily safer than something artificially made. But it's not true. Then what exactly does the natural flavour mean? It refers to extracts (提取物) got from natural sources like plants, meat or seafood. When consumers see the "natural flavour" on a label, they are unlikely to assume that someone is squeezing the juice from oranges into their bottles. They know even though natural flavour must come from natural sources, it needn't all come from the plant or meat. For example, orange flavours might contain not only orange extracts, but also extracts from bark and grass.

So if flavours like orange are needed, why not just use oranges? The answer comes down to "availability, cost, and sustainability", according to flavour chemist Gary Reineccius of the University of Minnesota. "If you're going to use all your grapes on grape soda," Reineccius says, "you don't have any grapes for wine making; the products are going to be exorbitant; besides, what do you do with the by-products you create after you've squeezed all the juice out of the grapes?"

Actually, while chemists make natural flavours by extracting chemicals from natural ingredients, artificial flavours are made by creating the same chemicals artificially. The reason why companies bother to use natural flavours rather than artificial flavours is simple: marketing. "Many of these products have health titles," says Platkin, professor from Hunter College. "Consumers may be talked to believe products with natural flavours are healthier, though they are nutritionally no different from those with artificial flavours. Natural flavours may involve more forest clear-cutting and carbon emissions from transport than flavours created in the lab."

Platkin suggests getting more transparent (易懂的) labeling on packaging that describes exactly what the natural or artificial flavours are, so consumers are-not misled into buying one product over another because of "natural flavours". Reineccius also offers simple guidance: "Don't buy anything because it says ‘natural flavours'. Buy it because you like it."
