It was a village in India. The people were poor. However, they were not unhappy. After all, their forefathers had lived in the same way for centuries.

    Then one day, some visitors from the city arrived. They told the villagers there were some people elsewhere who liked to eat frog's legs. However, they did not have enough frogs of their own, and so they wanted to buy frogs from other place.

    This seemed like money for nothing. There were millions of frogs in the fields around, and they were no use to the villagers. All they had to do was catch them. Agreement was reached, and the children were sent into the fields to catch frogs. Every week a truck arrived to collect the catch and hand over the money. For the first time, the people were able to dream of a better future.

    But the dream didn't last long. The change was hardly noticed at first, but it seemed as if the crops were not doing so well. More worrying was that the children fell ill more often, and, there seemed to be more insects around lately.

    The villagers decided that they couldn't just wait to see the crops failing and the children getting weak. They would have to use the money earned to buy pesticides(杀虫剂) and medicines. Soon there was no money left.

    Then the people realized what was happening. It was the frog. They hadn't been useless. They had been doing an important job—eating insects. Now with so many frogs killed, the insects were increasing more rapidly. They were damaging the crops and spreading diseases.

    Now, the people are still poor. But in the evenings they sit in the village square and listen to sounds of insects and frogs. These sounds of the night now have a much deeper meaning.

    People who increased the number of times they chewed their food before swallowing ate less each meal, according to a new study.

    Slow eaters tend to be slimmer. Before the study, the researchers didn't know whether asking people to chew more would change the amount of food they ate. But they found meal sizes became smaller when adults chewed more before swallowing——whether they were slim, normal-weight, overweight or obese.

    “The study proves the benefits of taking time to chew food well,” said dietitian Brown Giggs.

    The participants were asked to eat five pizza rolls and count the number of times they chewed each roll. Researchers did not tell them what exactly was being tested in the study. 47 people went on to finish the study. 10 were slim, 10 were normal-weight, 27 were overweight. Those participants attended three weekly lunchtime test periods. Each day, researchers gave them 60 pizza rolls and told them to eat until they were full. Depending on the period, researchers asked people to chew every bite the same number of times as at their test visit, 50% more or twice as many times.

    Slim participants ate more slowly than normal-weight and overweight participants. Overall, people spent more time eating when they increased the number of times they chewed. The participants rated their appetite (食欲) the same after each meal even though slower chewing reduced how much they ate.

    Researchers noted that the study was conducted under lab conditions, so it's not clear whether it would adapt to normal life. The researchers are now looking to see whether how fast people eat, for example, influences how much they eat. “It takes about 20 minutes for the brain to signal your stomach that you're full,” Brown Riggs said.

    “Fast eaters can eat a large amount of food within that 20-minute period causing more calories, which can lead to being overweight or obesity.”

    On average, Americans spend about 10 hours a day in front of a computer or other electronic devices and less than 30 minutes a day outdoors. That is a claim made by David Strayer, a professor of psychology at the University of Utah. In his 2017 TED Talk, Strayer explained that all this time spent with technology is making our brains tired.

    Using an electronic device to answer emails, listen to the news and look at Facebook puts a lot of pressure on the front of the brain, which, Strayer explains , is important for critical (有判断力的)thinking , problem-solving and decision-making.

So, it is important to give the brain a rest. And being in naure, Strayer claims, helps get a tired brain away from too much technology. More than 15,000 campers from around the world attended an international camping festival in September. That is when friends and family take time off and escape to nature for several days. They take walks, climb, explore, swim, sleep, eat and play. Camping may be just what a tired brain needs.

    Take Carl for example .He lives in West Virginia and enjoys camping. He says that staying outdoors makes him feel at ease. It also prepares him for the work he must do. Kate Somers is another example who also lives in West Virginia. She says she enjoys camping with her husband and two children. She calls it a “regenerative” experience.

    At the University of Utah, David Strayer has studied both short-term and long-term exposure to nature. He found that spending short amounts of time in nature without technology does calm the brain and helps it to remember better. However, he found, it is the long-term contact with nature that does the most good. He and his research team found that spending three days in nature without any technology is enough time for the brain to fully relax and reset itself.

    Ray Tokuda, a 54-year-old Japanese American, is proud of the title his school has given him. He is a Shifu, a Chinese word literally meaning a master, mentor or senior practioner of martial arts.

    Tokuda has reason to be proud. He has been involved with Chinese martial arts for almost four decades. After learning them at the martial arts school in New Mexico State, today he is among the most experienced kung fu teachers of the school.

    Practicing martial arts two to three hours and helping students improve their skills have become Tokuda's daily routine. He expects to practice and teach martial arts for the rest of his life. "I'm still learning. It's worth more than a lifetime to learn Chinese martial arts," he said." Once I started, I just couldn't stop. I think it's also the magic of Chinese culture."

    Tokuda was sent to the martial arts school when he was 10. He still remembers how unwilling he was when starting out." My father had always wanted to learn Chinese martial arts but never got the chance, so he put his kid in," he said. "I was so afraid at that time because I thought kung fu was all about fighting."

    But things changed after he learned that martial arts were more than punching and kicking.

    "One of the things martial arts teach me is overcoming adversity," Tokuda said. "As a little kid, my first lesson was like, oh, look, this is a thing that I can get through by diligence, perseverance(毅力)and dedication, and that was priceless for my life."

    Learning Chinese martial arts opened a gateway for him to better understand Chinese culture because he could hear a lot of ancient Chinese kung fu-related stories. "It is like in America, where we hear stories about knights in shining armor and King Arthur and noble deeds done," he said. "I feel martial arts preserve something of ancient China that can't be found in books. They are sort of an oral history."

    Tokuda has also been invited to various events in his home state to showcase traditional Chinese culture, including the dragon dance and lion dance, which he also learnt at the martial arts school. Because of this, he is now considered a cultural envoy (使者) in the eyes of the public.
