The study, published in the online issue of the American Journal of Preventive Medicine, found that about 40,000 patients were treated in US emergency departments for rock climbing-related injuries between 1991 and 2012. The most common types of rock climbing –related injuries were fractures(骨折) and sprains (扭伤)。The ankle was the most common body part to be injured (40%). Climbers in the study ranged in age from 2 to 74, with an average age of 26. The study also found that women took up a quarter of the injuries.
Falls were the primary reason for injury with over three-quarters of the injuries occurring as the result of a fall. The severity of fall-related injuries had a lot to do with the height of the fall. Patients who were injured after falling from a height over 20 feet were 10 times more likely to be treated than patients who were injured falling from 20 feet or lower.
“We found that the climbers who fell from heights higher than 20 feet took up 70 percent of the patients treated for a rock climbing-related injury,” explained the study author Lara McKenzie, PhD, director at the Center for Injury Research and Policy at Nationwide Hospital. “This trend, combined with the fact that rock climbers have a higher hospitalization rate than other sports and recreational injuries, demonstrates the need to increase injury prevention efforts for climbers.”

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(哲理) behind parkour. This is the same as life. You must determine your destination, go straight, and 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3】The Link between Fitness and Career Success
It’s no mystery to successful people that there is direct link between sound health & fitness and success in their cancer and personal lives. Successful persons likely show up at the health club consistently, work with a personal trainer, or get up a few minutes early for a heart elevating jog. Successful people like to jump start their day with plenty of energy and the feel-good endorphins(内啡肽)that exercise offers. Recent studies prove the direct link between fitness and success.
Better ability to focus, improved confidence and enhanced ability to follow through were directly attributed to improved fitness levels according to a 2007 University of Georgia study.
Further, a leading manager search company surveyed more than 1,300 managers. When asked to describe their viewpoints of weight and work, 75% said good physical fitness is “critical for career success at the manager level.” 17%, by contrast, said staying in shape is “a nice goal, but secondary to good fitness.”
The CEO of that manager search firm said, “Good physical fitness is critical to success as a manager in today’s work world.” When asked about obesity, 75% of managers said that being overweight is a “serious career impediment (妨碍)”. Do these responses reflect our obsession with weight loss and mirror the constant reports of skinny images in popular culture? Probably not. Rather, there is a very strong link between improved fitness and increased productivity, enhanced ability to solve problems, superior energy, not to mention reduced stress and tiredness, all leading to better job performance. It goes well beyond looking good. Fit people tend to have better eating habits and miss fewer days at work due to a higher resistance to illness. And with competition continually increasing in every industry, companies are now rewarding employees and managers who miss less work and produce more.
A study by Jim McKenna, a British researcher, showed that after exercising participants returned to work more tolerant of themselves and more forgiving of their colleagues. The study concluded that “work performance was consistently higher, time management skills improved, as did mental sharpness.”
All it takes is investing 3—4 sessions a week, 30—45 minutes each, to experience these benefits. Combine strength training and cardiovascular (心血管的) exercise, along with sound nutrition to speed up your mental sharpness, enhance your productivity, improve your mood and better manage stress. As your fitness level increases, likely your position on the ladder of success will too!

【推荐1】You don’t need to be a whale expert to know that these large animals are most at home in the depths of the world’s many oceans. You may not be surprised then, that there were no survivors when 477 pilot whales were stuck on New Zealand’s remote Chatham Islands in October in 2022. It was one of the country’s largest mass stranding (搁浅) incidents.
Although in the past local authorities were able to quickly send teams to try and rescue the whales, that perfect result was impossible this time. According to the New Zealand whale protection non-profit organization “ Project Jonah“,there were many difficulties concerning any attempt at saving the whales. The remote Chatham Islands have a small population, meaning trained medical medics (医护人员) would be unable to get to the scene in time. In addition, there was a risk caused by predators(捕食者) attracted to the beach which endangered both rescue teams and any other surviving whales.
As a result, the whales that managed to survive for a while onshore had their dreams of returning to the ocean cut short. The decision was finally made to euthanize all of the remaining living whales on the beach. Otherwise, it could have taken weeks for them to die naturally. Though the medical medics did so to put them out of their suffering, Daren Grover, the general manager of “Project Jonah”, described the outcome as “heartbreaking”, according to the New York Post.
This incident took place less than a month after 230 whales were found stranded on the Austalian island of Tasmania. Fortunately, about 30 of those animals were then able to be saved in time by local authorities , according to NPR.
The cause of these mass stranding incidents is not obvious at the moment, although various theories have been raised. Daren Grover said that there may be an issue with the animals’ echolocation ability - the sense that allows them to find their way through the water.
If whales are found in shallow waters, rescuers often play back recordings of the animals’ own calls to pilot them to the sea. A small number of whales will also be moved to large facilities for recovery.

【推荐2】When Ariel Cordova reached Jamaica Bay Wildlife Refuge in Queens, New York, last November, she planned to go hiking and bird-watching. A mile into her walk, she noticed a beautiful female mute swan (疣鼻天鹅) near the water’s edge. Cordova, who had worked at the Wild Bird Fund recovery center in Manhattan, knew that swans can attack people. But strangely, as she got close to this one, it didn’t move. So she was certain that the bird was ill and needed medical attention. Cordova put her jacket over the bird’s head to keep it calm, carefully picked it up, and held it in her arms. And then a thought came to her: What do I do now?
Her best choice was the Wild Bird Fund recovery center, but that was on the other side of town. How was she going to transport a 17-pound swan on foot all that way? Luckily, a stranger offered her a bike and then she took the swan to a nearby subway station by bike.
On the subway, no one seemed to be astounded by the feathered passenger. “Even one guy, who was sitting right in front of me, just gave the swan a calm glance,” says Cordova.
Cordova called the recovery center, and Tristan, an animal-care manger, picked her up at the subway station and drove the bird to the recovery center. There, staff members decided that the swan might have been hurt by a fish hook.
The staff looked after the swan carefully and got it back up on its webbed feet. The swan even made a boyfriend in the center. Sadly, it had a bacterial infection. Two months after Cordova came to its rescue, it passed away.
It’s a disappointing ending, but the real story is just how far some people are willing to go to save a swan in the big city literally (确实地). In all, Cordova traveled two hours by bike by subway, and by car to save it with endless efforts. Tristan says, “We are angels of love. That’s the perfect summary of who we are. I firmly believe that we will continue to save wildlife.”

【推荐3】Have you ever lost something in a hard-to-reach space, like behind a sofa or under the bed? Wouldn’t it be nice to just squeeze (挤) in and out to get it? New robots will soon make this happen.
In a study, scientists from the Chinese University of Hong Kong and Carnegie Mellon University in the US have invented small robots that can quickly change into liquid (液体) states. They melted (熔化) into liquid and managed to get out of a locked cage (笼子) during the tests, shocking the whole scientific community.
According to the website Mashable, the scientists got the idea from sea cucumbers (海参), which can change the softness of their bodies and easily enter any place .The robots in the study were made from a soft metal, which has a low melting point of only 30°C.The scientists firstly place the robot in a magnetic field (磁场). Thanks to the magnetic field, the robot can then be heated into a liquid form, allowing it to enter some hard-to-reach places. After that, by controlling the strength or direction of the magnetic field, the robot can be moved around in a controlled manner.
Hopefully, these liquid robots can be widely used in different fields and will not disappoint us. They can help take out a foreign object from a model human stomach. Scientists can use them to repair a TV set by squeezing them into hard-to-reach areas inside the TV set. To prevent humans from being harmed, these robots can perform dangerous tasks in hard-to-reach environments, such as cleaning in nuclear power plants (核能发电).
“What we’re showing are just ideas that need to be developed further,“ said Carmel Majidi of Carnegie Mellon University. “The goal of our future research is to put these liquid robots to use in real-life situations more quickly. We are very confident about achieving this goal.”
