Taking exercise in a crowded, noisy gym will improve your muscle but may not make much difference in your stress level. By contrast, hiking improves not only your physical fitness level, but your mental health as well. “I hike with friends every week. Whether I am wandering down a flat path along a river or climbing a rock y mountain in the wilderness, hiking can be beneficial to me because it exposes (使接触) me to outdoor scenes such as mountain s and rivers, which can always offer me good ideas about paintings and music,” Marry Copper, a hiker said.
Experts agree that hiking reduces stress. According to the Anxiety Disorders Association of America (ADAA), hiking increases the body’s production of endorphins, a type of chemical that improves mood (情绪). Endorphins also help you sleep more soundly, which will lower your stress level. However, not all scientists agree that hiking raises your endorphin level. Instead, some researchers believe that hiking causes the release of the chemical norepinephrine, which helps make you less excited or upset.
The controversy (争议) is ongoing, but it is clear that however it happens, hiking is useful when you are feeling anxious. Hiking can also help improve your confidence. Walking down a path is a repetitive motion, which can lead your brain into relaxing; you may “zone out” to the point where you won’t be thinking about anything in particular. Being outside in the open air may also help you exercise better because most people do indoors; getting out from under a roof can lift your spirits.
Hiking may improve your mood more than a gym workout will, but your risks are also greater. People sometimes try to make their own way rather than stick to established paths. They are proud to say they like to have an adventure. However, people who try to do something new could be attacked by wildlife and get hurt and lost. So stick to the known roads and bring a cellphone with you, and always tell someone where and when you are going hiking, even if you have a partner going with you.

【推荐3】“Our aim is to take our art to the world and make people understand what it is to move,” said David Belle, the founder of parkour.
Do you love running? It is a good exercise, yet many people find it boring. But what if making your morning jog a creative one? Like jumping from walls and over gaps, and ground rolls? Just like the James Bond in the movie Casino Royale? Bond jumps down from a roof to a windowsill and then runs several blocks over obstacles on the way. It is just because of Bond’s wonderful performances that the sport has become popular worldwide.
Yes, that’s parkour, an extreme street sport aimed at moving from one point to another as quickly as possible, getting over all the obstacles in the path using only the abilities of the human body. Parkour is considered an extreme sport. As its participants dash around a city, they may jump over fences, run up walls and even move from rooftop to rooftop.
Parkour can be just as exciting and charming as it sounds, but its participants see parkour much more than that.
Overcoming all the obstacles on the course and in life is part of the philosophy behind parkour. This is the same as life. You must determine your destination, go straight, jump over all the barriers as if in parkour and never fall back from them in your life, to reach the destination successfully. A parkour lover said, “I love parkour because its philosophy has become my life, my way to do everything.”
Another philosophy we’ve learnt from parkour is freedom. It can be done by anyone, at any time, anywhere in the world. It is a kind of expression of trust in yourself that you earn energy and confidence.

【推荐1】Growing up, Cassie Holmes was known as “Little Miss Happiness”. A cheerful outlook seemed to come naturally to her — or at least nothing in her life suggested that the word was anything but a sunny place.
Then, just a week before she was to marry her childhood sweetheart, her cellphone rang: her fiance had abruptly decided to call things off. The experience left her ashamed and depressed. “I was confronted with the harsh reality that had things happened,” Ms. Holmes writes. “Feeling this depth of unhappiness forced me to realize that I shouldn’t rely on my preference to experience happiness going forward.”
Ms. Holmes, a social psychologist at UCLA’s Anderson School, was studying exactly how people can make themselves feel better and get through tough situations. In “Happier Hour: Focus on What Matters Most”, she vividly conveys what she has learned from her study. Happiness is a well-covered topic, and so Ms. Holmes has focused her research on how people can spend their time to boost well-being.
One of the first misconceptions she tackles is that more free time is always better. Her analysis of time-use data and well-being finds that people are the happiest with 2 to 5hours of free time per day-a nice reality check for anyone fantasizing (幻想) about quitting a job to move to a tropical island. It is also a comforting statistic for those who, like Ms. Holmes, are raising young kids. Two hours is achievable if 10 is not, and 10, it turns out, may not be better anyway.
Life will always include episodes and events that almost seem to lower our spirits. “Happiness is a choice,” she writes. “How we decide to approach our hours and spend our days determines the happiness we get to enjoy in life.”

【推荐2】A 15-year-old Colorado high school student and young scientist who has used artificial intelligence (AI) and created apps to address polluted drinking water, drug addiction and other social problems has been named Time Magazine’s first-ever “Kid of the Year”.
Rao told The Associated Press in an interview from her home that the prize is nothing that I could have ever imagined. And I’m so grateful and just so excited that we’re really taking a look at the upcoming generation and our generation, since the future is in our hands.
Time said Rao stood out for creating a global community of young innovators and inspiring them to pursue their goals. Rao insisted that starting out small doesn’t matter, as long as you’re passionate about it.
She told Time contributing editor Angelina Jolie in an interview that her science pursuits started early as a way to improve social conditions. The drinking water crisis in Flint, Michigan, inspired her work to develop a way to detect pollutants and send those results to a mobile phone, she said.
“I was like 10 when I told my parents that I wanted to research carbon nanotube sensor technology at the Denver Water quality research lab, and my mum was like, A what?” Rao told Jolie. She said that work is going to be in our generation’s hands pretty soon. “So if no one else is gonna do it, I’m gonna do it.”
In a world where science is increasingly questioned or challenged, Rao insisted that its pursuit is an act of kindness, the best way that a younger generation can better the world.
“We have science in everything we’re involved in, and I think that’s the biggest thing to put out there, that science is cool, innovating is cool, and anybody can be an innovator.” Rao said, “Anybody can do science.”

【推荐3】We often see beautiful butterflies flying around us. If you have ever tried to catch a resting butterfly, you know it is surprisingly difficult. A new study helps explain why.
Previous research had suggested that a butterfly’s overhead wing clap forces the insect forward. Researchers thought the wing clap likely formed a pocket of air that shoots out like a jet. But no one had tested that until now.
To analyze their flight, they placed six butterflies one at a time inside a wind cave which was filled with smoke and then used a laser (激光灯) to light up the smoke just behind the butterfly. Four high-speed cameras were placed in the cave to take photos of the movement of the butterfly and the smoke as the butterfly was taking off. This let the researchers create a 3D picture of that air movement as the insect flapped its wings.
They analyzed a total of 25 takeoffs by six butterflies. Each included up to three wing beats after takeoff. The butterflies proved more likely to clap their wings together during the first few wing beats than later in flight.
The photos show that forces created by the wings give rise to a flight path. The butterflies rise as their wings move down and shoot forward as their wings move up. A wing clap on takeoff, paired with a quick turn, allowed the butterflies to fly away quickly. They also noticed the wings formed an air pocket just before clapping and that the wings’ flexibility and this pocket improved the jet force created by the clap.
“The study is exciting,” says Ayodeji Bode-Oke, a mechanical engineer in Charlottesville. That means “we have solved the longtime puzzle about how butterflies fly, and it proves nothing is impossible on the road of scientific research. I can’t wait to learn about how the study might inform designs for small flying vehicles.”
