The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid—we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.

    However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard (蜥蜴)native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water's surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we，d need huge feet that we could bring up to our ears in order to create adequate w hitting.

    But fortunately there is an alternative : cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a “non-Newtonian” liquid that doesn't behave like normal water. Now, if the surface of the water is hit hard enough, particles(粒子）in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick Liquid of cornflour.

    Fun though all this may sound, it's still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink--and take a shower afterward!

    “Fast fashion” means clothes that are inexpensive but look like the latest designs. One reason for the success of fast fashion is social networking. A report by the investment research firm Bernstein found that millennials — people born in the 1980s and 90s — wanted to wear a variety of clothes in the photos they posted on Facebook, Instagram and Twitter. As a result, many businesses that offer trend, low - cost clothes are growing.

    But the situation is changing now. Maxine Bedat, a woman who is in her early 30s，looks in her closet full of clothes, but she has nothing to wear. She says she hates always shopping for what is in style . Instead，she says, she wants to buy fewer clothes that she can wear over and over. Other people want the same thing, she says.

    So Ms. Bedat and a business partner, Soraya Darabi, started a “slow fashion” clothing company calltd Zady. “Slow fashion” means clothes that last a long time. They are often classic colors and shapes, and are made from natural materials that are biodegradable (可生物降解的) over time.

    The terms “fast fashion” and “slow fashion” are related to “fast food” and “slow food: fast food is still popular in the US, but many restaurants increasingly offer higher - quality, more expensive and relaxed meals.

    Like slow food，slow fashion also aims to use sources that are good for the environment and 、 workers. Maxine Bedat says people in her generation want to know where their clothes come from and who is making them. To answer millennials'demand for information about the products they buy, Ms. Bedat's company, Zady, includes details about the history of the brands. It also describes the process in which the clothes are made. Ms Bedat says Zady aims to tell shoppers where their clothes come from, where they go, and how they impact the world.

    How's your happiness quotient (指数)? Science tells us that if you want to increase your "happiness quotient" every day, it's important to take time and accept the present blessings (恩赐) in your life.

    I wanted to share a moment of feeling about some of my blessings and what's in my life to be grateful for as Thanksgiving approaches.

    One of our family traditions at our Thanksgiving meal is to go around the table and to let each one share something we're especially thankful for.

    I'm going to recite lots of things, including that I'm grateful for my health, my loving husband, and the wonderful relationship we share. My husband joins me for 3-mile walk to start our day. The exercise habit keeps our moods in check and the ups and downs of life easier to manage. We talk as we walk, sharing ideas, worries and good feelings too. Sometimes we argue a little until we figure out what to do. We always come up with something. What a blessing that is!

    It is so much to be grateful for. I feel I am the luckiest woman alive. It's my wish for you that you'll be able to spot something in your life. I hope yet you will savor (体味) and appreciate it.

    Many of us spend the holiday with our aging parents or other loved ones. In my work at AgthgParents.com, we just reminded everyone that you never know if there will be another Thanksgiving with these loved ones. We can't take the day for granted. Just be in the moment. We suggest that you verbally give thanks to your parents, no matter what conditions your aging parents may be in now. Do what you can to be tuned in to what you need as well as what your family needs.

    From ancient stories to modern researches, the label（标签）attached to being left-handed is undeniable. Left-handed people, or "lefties" as they are often called, are generally believed to be good at art — Leonardo da Vinci, Picasso and Michelangelo are all left-handed.

    Our brain is divided into two parts: the left hemisphere(大脑半球)and the right hemisphere. The left hemisphere, linked to logic and analysis, is responsible for the right side of the body. The right hemisphere, linked to creativity and imagination, controls the left side of the body. So, people tend to believe lefties are controlled by the right side of the brain, and are more creative than right-handers. Some also think that lefties may not be as good as right-handers in mathematics and problem-solving skills.

    However; a recent study carried out by scientists from the University of Liverpool in the UK and the University of Milan in Italy proved this theory wrong. The study involved(涉及)more than 2,300 students in Italy aged between 6 and 17 years old. They were asked to complete several mathematical tasks of different levels. It turned out the left-handers outperformed the others when the tasks involved difficult problem-solving. This pattern was particularly clear in male adolescents. However; when it came to simple arithmetic, there was no difference between left-handers and right-handers.

    It was also discovered that those who are "severely" right-handed performed less well in all the experiments compared to "medium" right-handers and left-handers.

    "Taken together, these findings show that handedness does influence abilities to some degree," the study's authors wrote. However, "handedness is just an indirect expression of brain function," wrote psychology professor Giovanni Sala from the University of Liverpool in the UK, the lead author of the study. Sala also noted that only one third of people with a highly-developed right side of the brain are left-handed. It means that there are lots of right-handed people with a similar brain function as left-handers.

    Runners never forget crossing the finishing line at their first marathon, and that will be especially true for Mike Kohler. When Kohler crossed the starting line in Fargo last Saturday, he thought he was going to run 13.1 miles, his first half marathon. Six hours later, he had "mistakenly” completed his first full marathon, 26.2 miles.

    Kohler, a 26-year-old plumber (水管工) who now lives in West Fargo, had lined up for the half marathon that he hoped to complete in 150 minutes. He didn't realize he was in a starting fence with the full marathoners. Several miles later, Kohler began to realize he was on the course for the full marathon. "The 8-mile mark was when I figured out that I had made a mistake," he said. "Between then and 13.1, I debated with myself about what I should do."

    At some point — he doesn't remember when — he doubled down on the distance. "After I decided I was going to keep going, the thought of quitting didn't come back. Run, walk, or crawl, I wanted to finish," he said.

    Until Saturday, Kohler's longest race was a 10-kilometer run, just over 6 miles. Even the most casual marathoners do a training run of 18 miles before the race. From his experience, he said he learned one thing: sometimes people can do more than they think they can.

    After his long race, he went right back to work, put in a 10-hour day and then boarded a flight to Scotland for a vacation. "I was pretty sore, but I found the more I kept moving, the less sore I was, so I tried my best to go about life normally — minus running,” Kohler said from Glasgow. "I needed a break from that for a bit."

    Not for too long, though. He's already considering the Bemidji Blue Ox Marathon in October.

When it comes to sitting properly, we all know the correct way even if we don't do it to the letter. No crossed legs, bottoms touching the back of the chair and feet on the ground. But even if you're doing it right, sitting for long periods is shockingly bad for you. It has been described as the new smoking, linked to heart disease and even cancer. There is no doubt we should all try to do less of it. But perhaps we could also do it better.

A classic survey, published in 1953, described 100 different sitting postures adopted by 480 cultures around the world. Among the most common were sitting cross-legged, kneeling and the deep squat (深蹲), with feet flat on the ground and bottoms resting on or just above it. Even in Western cultures, these are preferred sitting positions among young children. But Westerners tend to prefer chair use from an early age, insisting children sit on seats in school.

One big problem with this desire for chairs is that they make sitting so, well, sedentary (久坐不动的). Consider the Hadza, a group of hunter-gatherer people in Tanzania. They spend around 9 hours a day sitting. However, they squat and sit on the ground in various positions, and this involves high levels of muscle activity. The supportive nature of chairs, with their high backs and armrests, removes this effort perhaps the reason that people love them.

So what's the best way to sit? Josette Bettany-SaItikov at Teesside University, UK has found that kneeling can help keep the spine in a better position as does squatting. We might also take inspiration from traditional cultures like the Hadza. "Use a variety of postures and preferably not just still postures but some which allow movement," says Bettany-Saltikov.

Bettany-Saltikov believes that we should be rethinking what it means to do a desk job. "We still need to design workplaces that enable people to be productive while being lightly active, like with under-table cycling or walking desks," she says. For now, if your job is sedentary, don't forget to stand up regularly and move around.
