Mobility is often confused with flexibility, but the two are distinct concepts. Flexibility refers to how far a muscle can stretch, while mobility combines strength with the ability to move freely through a full range of motion. It involves the coordinated function of muscles, joints, tendons, and ligaments. Without adequate mobility, everyday tasks such as reaching overhead, bending down, or lifting objects can become challenging.

From around the age of 30, the body naturally begins to lose collagen (胶原蛋白), leading to weaker muscular support and increased stress on joints. Even active individuals may overlook certain muscle groups, such as those supporting the shoulders and spine. Two early signs may suggest the need for mobility training: first, general joint stiffness or aching without significant exertion; second, sharp pain or swelling after occasional physical activity, such as playing sports.

Experts warn against extreme self-tests popular on social media, which can easily cause injury without proper guidance. Instead, simple assessments like standing up from a chair without using hands or balancing on one foot can indicate current mobility levels. To maintain or improve mobility, regular low-impact exercises are recommended.

Walking daily is an accessible starting point, especially for those who are less active. Integrating short mobility sessions into existing routines—such as hip lifts, knee pulls, or spinal twists—can gradually enhance movement capacity. Exercises like Tai Chi and yoga are also beneficial as follow-up practices, as they promote strength, balance, and joint mobility.

For those seeking a structured workout plan, body-weight exercises like chair squats or wall push-ups can be done at home. As these become easier, resistance bands may be added to build further strength. Consistency is key; improvements in mobility may take several weeks to become noticeable, but regular, intentional practice leads to lasting and meaningful results.

In summary, focusing on mobility through safe, regular exercises helps preserve functional independence and supports overall well-being throughout aging.

Rather than relying on coffee and endless yawns to try and make it through the workday, Koyoju Plywood Corporation declared about the "Giraffenap" that the nap box will allow you to "be refreshed" in just 20 minutes.

Giving in to your sleepiness and taking a 20-minute nap will apparently help improve your performance by recovering from tiredness, reducing stress, restoring memory and concentration, and improving creativity. A study by NASA has found that pilots who took a 26-minute nap experienced a 34 percent improvement in performance, and a 16 percent improvement in reaction time. "As a new way to take a break, we will provide a space where you can take a nap while standing in the office," the site explains.

But why does it have to be standing? Well, the site explains that the research by Hokkaido University showed that sleeping while standing allows you to reach a sleep state in which you breathe lightly, so when you wake up you can feel the effect of a nap without having to sleep too much, and you can quickly return to work without feeling dizzy. Plus, making the box vertical (垂直的) rather than horizontal means that it takes up half as much floor space and makes it less likely that your boss will say there just isn't room. The box also comes equipped with a fire extinguisher, smoke detector, and LED lighting for safety, and it blocks out sound from the outside to ensure a calm, sleep-worthy environment.

Now, I know what you're thinking—wouldn't you just fall down if you tried to sleep while standing? Well, not with Giraffenap's design. The box is equipped with four points to support the body at the head, butt, legs and feet, meaning you can relax in the box while still remaining upright.

Nakashima had a clear goal. He intended each piece of furniture he made to be as perfect as possible. Even making a box was an act of creation, because it produced an object that had never existed before. Initially Nakashima used local wood, sometimes from his own property. Later, he traveled to seek out English oak, Persian walnut, African zebra wood and Indian teak. He especially liked to find giant roots that had been dug out of the ground after a tree was taken down. Nakashima felt that making this wood into furniture was a way of allowing the tree to live again.

Most furniture makers prefer perfect boards, but Nakashima took pleasure in using wood with interesting knots (节疤) and cracks. These irregularities gave the wood personality and showed that the tree had lived a happy life.

He never failed to create an object that was both useful and beautiful. One early piece Nakashima designed was a three-legged chair for his small daughter Mira to use when she sat at the table for meals. The Mira chair became so popular that Nakashima later made both low and high versions. Another famous piece, the Conoid chair, has two legs supported by blade-like feet. Always, Nakashima's designs were precise and graceful, marked by simplicity that revealed his love for the wood.

As the years passed, Nakashima's reputation grew and his works received many awards. His children Mira and Kevin, now adults, joined the team of craftspeople in their father's studio. Nakashima's dream of integrating (合并) work and family has come true.

Traveling to China is no longer a luxury for many foreign passport holders. The Chinese government has permitted a 72-hour visa-free policy that offers access to visitors from 53 countries including the US, France and Austria. Let's start with the capital of China, Beijing. Here's a pick of the best in Beijing!

Mutianyu Great Wall

Your trip to Beijing isn't really complete without seeing one of the "New Seven Wonders of the World" ，the Great Wall of China. The Mutianyu section of the Great Wall is by far the most well-preserved of all. Taking a one-hour bus ride, Mutianyu would be your ideal location for a half-day of hiking away from the large crowds in the city. Also, the authorities have allowed tourists to paint graffiti on a specific section of the Great Wall since 2014. The Great Wall was designated （把….定名为）

a UNESCO World Heritage site in 1987.

Summer Palace

Located in northwestern Beijing, the Summer Palace is by far the city's most well-preserved royal park. With its huge lake and hilltop views, the palace offers you a pastoral escape into the landscape of traditional Chinese paintings. The Summer Palace was added to the UNESCO World Heritage List in 1998.

798 Art Zone

This would be on the top of my list! Named after the 798 factory that was built in the 1950s, the art zone is home to various galleries, design studios, art exhibition spaces, fashionable shops and bars. You could easily spend half your day wandering around the complex, feeling the contrast of the present and the past.

Sichuan Provincial Restaurant

While in Beijing, apart from trying the city's best-known Peking duck, the Sichuan provincial restaurant is one of places where you can enjoy regional delicious food. It offers one of China's eight great cuisines, Sichuan Cuisine, which ranges from Mapo tofu to spicy chicken.

An Unexpected Angel

In the extreme heat, I watched an elderly woman struggle with bags of groceries. Slowing down, I opened the window and called out, "Need a ride?" I helped her into the passenger seat, and we were off.

She directed me to go farther south. Suddenly, I realized we were on the "wrong side of town." It was starting to get dark, and I began to feel uneasy. We continued down unfamiliar streets until she finally pointed to an old apartment building. The street was dirty and the air was smelly. Several young men gathered around the entrance. They appeared threatening. Some were on motorcycles, and one boy with bushy, long hair was staring at me intently (目不转睛地) — too intently — and smiling.

I was getting more and more uncomfortable. I stopped the car. A couple of the guys helped with the groceries. The old lady thanked me, and I drove away as fast as I could.

I was driving when I was interrupted by a motorcycle behind me. It was that boy who kept smiling at me with a strange look! In a panic, I slowed down, hoping he would pass me. But he continued to drive at the same speed as me. I realized he was waving for me to stop.

No way was I going to stop for a stranger on an unfamiliar street. I tried to speed away, but it didn't stop him. He raced after me again. Getting increasingly anxious, I reached down in the passenger seat to get my cell phone. I had to call 911.

With my eyes on the road, one hand on the wheel and the other hand searching on the seat next to me, I found a phone. But it wasn't mine. "Oh no, the lady took my phone by mistake!" Meanwhile, the guy on the bike stayed close to me.

Research has shown that a preference for sweet foods is associated a kinder, more agreeable personality. The association can be seen in the language (use) to describe people who are nice or whom we love in some culture, such as "sweet", "sweetie", or "honey".

These links can (explain) based on the conceptual metaphor theory and the center ofis that metaphors compare abstract concepts to more concrete fields to help understanding. In the theory, metaphoric mappings are cognitive association, often learned through experience or a process of embodiment (具象化), eventually allows people to think about or represent abstract concepts in terms that are more readily perceptible(可感知的), such as taste.

A new journal article published this week, which I am a co-author, aimed to examine whether the association between sweet taste preferences and agreeableness occurs across cultures. (address) this question, the study surveyed 1,650 participants of different cultural backgrounds.   

The study found that agreeableness was (significant) and positively connected with the two different measures of sweet taste preferences in all samples. Compared with ones without a sweet tooth, people who like sweet foods are (likely) to "sympathize with others' feelings", "take time out for others", "have a soft heart", and so on. Therefore, the study's results suggest that people across cultures use sweet taste experiences to understand and conceptualize a person's inner (warm) in line with theory framework.

I still remember the first one. I was5 by how organic the sound of the piano was, as I had become familiar with the6 electronic sounds. The teacher was trying to explain where middle C was, but I could already play all the major and minor scales. After eight lessons, I7 my grade one and got distinction. By the time I started secondary school, we couldn't afford lessons again, so I returned to my paper keyboard. I passed grade three, then grade five, practicing only on my piece of paper.

For the grades above that, there is an8 that you add a certain sensitivity into your playing. The music teacher at my school said I could practice on the school's grand piano. I would wake up at 5:30 am to get there in time and play until lessons started. I'd9 lunch and practice after school until the caretaker kicked me out. At home, I'd have dinner, do three hours of revision, and then10 practice until 1:00 am.

My school didn't offer music A-level. I found the Purcell School for young musicians. The audition was extremely11, and I felt overwhelmed. To my amazement, I was offered a12. I had been told I had started playing too late to reach conservatoire level, but when I left Purcell, I was awarded the senior piano prize. That was the point when I realized I wasn't behind everyone else. I am now at the Guildhall School in London, where I was offered a scholarship. I feel proud: it's been 10 years since I drew my paper piano and I'm at one of the world's13 conservatoires. The irony is that I continue to do a lot of my practice away from the piano what we call mental practice. It14 key areas of the mind that are less readily accessed by piano playing alone. The paper piano helped stimulate my15 about how music works.

Before knowing how to get rid of bad dreams, we need to understand what can result in them. Researches have shown that when a person is under some sort of physical or mental stress, he is more likely to get bad dreams and disturbed sleep. For instance, if you're overworked, learn to take things slow. Don't be ambitious to the point that it starts affecting your health.

Besides, some trauma (损伤) that a person might have experienced recently or in the past which they're unable to get over can make the person suffer from bad dreams. Death of a very close family member is often seen to be the reason behind recurrent nightmares.

Eating fatty and high-protein foods in dinner is also known to cause bad dreams in some people. Taking a light dinner of soups and salad is the best, both for the health and for stopping disturbed sleep in some cases.

Besides these, there are many other things a person can do to have a good night's sleep. For example, your bedroom should be the most comfortable place in the world. It's advisable to get rid of all electronic gadgets including television. So, from now on try to be a happy and positive person.

A. Almost everyone has this experience.

B. Take proper exercises and this might help you.

C. Bad dreams occurring because of these reasons can be stopped if the diet is changed.

D. That's why one should take steps to stop them as soon as they become an everyday occurrence.

E. In such a case, taking therapy and dealing with the trauma is the only solution to stop bad dreams.

F. In addition, if you have negative thoughts, it can have side effects on the kind of dreams you have.

G. So, to stop bad dreams, it's necessary to find out the causes of physical and mental stress in your life.

By growing the mushroom's mycelium (菌丝体) into the robot's hardware, a team led by Cornell University researchers has engineered two types of robots that sense and respond to the environment by using electrical signals made by the mushroom and its sensitivity to light.

The robots are the latest accomplishment of scientists in a field known as biohybrid robotics who seek to combine biological, living materials such as plant and animal cells or insects with artificial components to make partly living and partly engineered entities.

There's still a long way to go before biohybrid robots go beyond the lab, but researchers hope one day robot jellyfish may explore oceans, sperm-powered robots may be able to deliver fertility (生育) treatments and cyborg cockroaches could search for survivors in the wake of an earthquake.

"Biohybridization is an attempt to find components in the biological world that we can use, understand, and control to help our artificial systems work better," said Shepherd, a professor of mechanical and aerospace engineering at Cornell University. 

The team began by growing king oyster mushrooms in the lab from a simple kit ordered online. The researchers chose this species of mushroom because it grows easily and quickly. They cultivated the mushroom's mycelium, which can form networks that, according to the study, can sense, communicate and transport nutrients.

The team found it challenging to engineer a system that could detect and use the small electrical signals from the mycelia to command the robot. "You have to make sure that your electrode (电极) touches in the right position because the mycelia are very thin," said lead author Anand Mishra. "Then you culture them, and when the mycelia start growing, they wrap around the electrode."

The primary value of slang has been to create linguistic markers, a way to set you apart from other people. The terms change over time, but the meanings typically don't — one generation's "cool" becomes another's "dope."

Members of my son's generation have a vastly superior approach to slang. They have invented a language that responds to the new and distinct reality they face, a society characterized by collapsing institutions, erosions (削弱) in trust and a loss of faith in a shared sense of meaning．

"Mid," for example, in my son's usage, describes things that are average or slightly below. You can't really complain about them, but they produce no joy. Everything in Starbucks and airports falls into the category of "mid."

"Glazed" has a similarly impressive precision, indicating the act of positively spinning a judgment on reality rather than complete lying. It is the perfect description of the way social media works, with everything taking on an artificially positive, unreal and not entirely trustworthy look. For example, beach photos on social media might make a destination look like paradise, yet they rarely show the crowded shores or bad weather that are part of the reality．

My favorite slang word is "based," often used to express agreement when someone states a controversial opinion. "Canada should join the United States," one might say, to which someone else might reply, "Based." To my ear, "based" is a perfect word to describe the informational chaos we inhabit．

Slang has brought my son and me closer. It's taught me that the current crop of teenagers created a language to describe the flawed reality we've abandoned them to, and in doing so they've proved themselves less misguided and more innovative than we were．

Andy stared at the white envelope on his desk. The Student Affairs Office logo in the corner made his stomach sink. He opened it slowly.

Health and Safety Warning.

Fine(罚款): $300.

Three hundred dollars — his entire summer earnings, meant for books and a winter coat. Now gone, all because of a messy room!

Andy was a quiet international student who kept his side of the dorm perfectly organized. For him, neatness brought calm and control. His roommate, Eric, was the opposite: he lived in what could only be described as a happy mess. Clothes piled on his chair, empty snack bags collected on the floor, and the shared waste bin always overflowed. But Eric was kind — he'd shown Andy around campus, helped with his homework, and lifted his spirits when he was homesick.

Andy was grateful. He never complained. He didn't want to start a fight. So, he'd sigh and quietly take out the garbage, thinking it was a small price for such a good friend. But he'd been home for two weeks — and returned to this. Now. holding the letter, he felt it was a big mistake. "I've been cleaning up his mess, and I get fined too?" he thought in frustration. This wasn't fair. His usual "avoid trouble" plan had failed.

Just then, the door flew open. "Andy! You won't believe the game today..." Eric's energetic entry stopped short. "Whoa. You look pale as a sheet. What's wrong?"

Without a word, Andy held out the warning letter. Eric took it, his smile fading as he read. "Oh, no. A fine? Three hundred? I'm... I'm really sorry." He looked from the letter to the pile of pizza boxes in the corner, which he'd meant to throw out for days, then to Andy's spotless desk. Real guilt washed over his face. "I've been completely careless about this. I'm sorry Andy..."

Distant pleasant music floated above the Sydney Opera House stage. Soft light gradually revealed motionless figures at work, as if lifted the pages of a Ming-dynasty book. Slowly they began to move. Accompanied by the soft sound of page turning and the gentle flow of water, their graceful (gesture) formed a living picture of labour.

This breathtaking opening of the dance drama Tiangong Kaiwu pulled me (instant) into that world of ancient creation. Through (express) movement, the performance conveyed the book's core message — (value) the skills passed down by countless unknown labourers and the power of practical tools. The beautiful scenes of golden fields and shiny silk made me feel the deep bond between humanity and nature.

The most moving moment came Song Yingxing took off his official robe (官袍) and stepped into a "field" formed by the other dancers. All motion ceased; only his figure remained, arms stretched upward, silent yet full of strength. At that instant, history   (it) seemed to hold its breath.

As I left the theatre I overheard a visitor say "This is beauty that (go) beyond borders." His words deepened my belief: art (root) in a culture's finest traditions possesses a timeless power to move anyone. This was more than ancient book brought to life — it was a celebration of Chinese wisdom and its spirit of sharing with the world.

Flying terrifies me—heart racing and legs shaking. I'm not2. Research shows many share this fear. And for me, frequent short work flights only made it3, especially those lonely late-night ones.

With a visit to China coming, I4 for an airline-offered course called "Flying with Confidence". At the airport, I was5 by how many others had paid £399 to face the same fear. Among them was Mia, who stopped flying after a sudden panic attack. Now pregnant (怀孕), she wanted to6 passing her fear down to her child.

Pilots led the morning session. Learning7, like a plane gliding (滑行) 100 miles if engines stop, was comforting. They emphasized the8 safety rules and over 100,000 safe flights daily.

The afternoon focused on9. The doctor patiently explained that "fear of fear" is common. He taught "breathe and squeeze" — slow breaths to control stress chemicals, and muscle squeezes to focus the mind. We practiced and it10.

Then came the11 flight. As we boarded, earlier excitement turned to obvious12. Captain Miller provided a calming broadcast. When turbulence (气流) hit, I used the13 technique. For the first time, panic didn't14.

The moment I exited the plane was emotional. My hands were still shaking, but my heart was already racing15, to my daughter in Beijing.

For older adults, activities like attending a songwriting workshop or joining a chorus go beyond mere leisure. They become a pathway to what Aristotle called "eudaemonia", a life well-lived.

Music offers a unique way for such meaningfulness, which often grows from deep connection. Whether it is the dedication to mastering an instrument, the excitement of creating music on the spot, or the sweetness of listening to a familiar tune, older adults do not engage in music as lone individuals.

Such meaningful involvement can even turn musical tools — a piano, a violin, or a digital device — into extensions of the person. This reflects the saying, "You are what you do." Some famous musicians travel with their own instruments, which proves how deeply music can shape personal identity.

As dancer Twyla Tharp remarked, "Art is the only way to run away without leaving home." The emotional uplift indirectly supports health by boosting memory, lowering stress, and strengthening social ties — all crucial for aging well.

Deep engagement in music adds meaning to later life, bringing happiness through creativity and commitment. Actually, music enriches lives at every age, so promoting creative expression through it should be a central aim in education and enrichment for everyone.

A. It's mostly the result of external entertainment.

B. Becoming a "musician" is thus a worthy goal for older adults.

C. They bond with others, culture, and their own growing sense of self.

D. The more often one plays an instrument, the greater joy one may gain.

E. Creative musical experience also provides an escape from daily routines.

F. With skill and regular practice, the instrument becomes part of who one is.

G. This is not brief pleasure, but lasting happiness that comes from living meaningfully.

Led by physicist Yao Xuri from Beijing Institute of Technology, the team has built a device that photographs the tiny, imperceptible vibrations that sound waves generate on objects. According to Yao, "This technique enables sound detection using everyday items under natural lighting."

This is hardly the first attempt to make a microphone that works with light. Alexander Graham Bell built one back in 1880. He called it a photophone. It operated by using sound waves to deform a mirror, causing reflected light to flash along with the sound. These flashes were then changed back into sound. Modern attempts have been trying to copy this, using high-speed cameras or precise lasers (激光), but such systems are often complex and costly.

The Chinese team has adopted an alternative approach: single-pixel (单像素) imaging. "Unlike ordinary cameras which rely on millions of sensors, single-pixel imaging uses just one," Yao noted. It scans a scene to collect visual data, which is then processed by computers to reconstruct an image. Through this technique, Yao's team detected how sound waves had shaken a paper card or leaf. A computer then decoded the data into audible sound.

The device successfully captured spoken numbers in both Chinese and English and decoded an excerpt from Beethoven's Für Elise. "This method creates a relatively small amount of data, making it easy to store or upload," Yao noted. The team is refining the device's capacity to detect human heartbeat and heart rate, a development that could enable non-contact patient monitoring in medical settings.

Currently, the technology only works from about half a meter away, and detecting sound in noisy environments remains a key challenge. That will take more advanced technology and extensive field testing. But if they succeed, we might not just listen to the world around us — we might watch it speak.

Meanwhile, students are using faculty office hours and the speaking and writing centers less. In last year's computer science courses, scores on problem sets increased, yet exam scores declined. "This is concerning," noted Hampson. "If they were using AI as a study pal, they weren't absorbing as much as they might think."

Students want clearer AI policies, and Hampson advised faculty to carefully consider and share what level of use they permit, the reasoning behind it, how to cite use of AI, and examples of what's permissible. He also encouraged department-wide discussions to best prepare students for a workplace where they will need to know how to write or code with its assistance. "I also believe that students need to learn to write and code unaided, to develop critical thinking skills, their agency as citizens, and also meaning — making the ideas that help them understand their own lives," he added.

Some professors expressed concerns about how AI use is impacting students' mental health and learning. Professor George Wilson noted that students are often highly competitive, and "it's important to create rules so that competition leads to healthy behaviors that make them better educated people." While some suggested more one-on-one time with students, others noted that budget restrictions would make that difficult.

Professor Poly Burnett observed that lecture attendance is also down. She urged faculty to make lectures something students genuinely want to attend. She also noted that many teachers are making small changes, in hopes of continuing teaching as they've previously taught. "We actually have to see this less as a problem and more as an opportunity," Burnett suggested. "How can ETU lead in rethinking how we teach, how we learn... and have our students be benefiting and being at the leading edge of that?"

For eleven years, the Amazon was my home, my school, and my proving ground. I faced constant dangers, from disease-carrying mosquitoes and snakes to flooding rains. I was struck down by both yellow fever and malaria. My routine was strict: mornings collecting, afternoons reading and preparing my finds. I was usually in bed by nine. My field journals, filled with detailed drawings and notes in dark ink, were my defense against the dampness and insects. I learned the local languages and customs, for without the crucial guidance of its people, I would have been completely lost in that vast wilderness.

It was a time of extraordinary variety. I brought back over 14,000 kinds of insects — 8,000 new to science. But the real wonder was not the count, but a pattern I noticed. It started with a puzzle: why could slow-flying butterflies like the Heliconius escape birds? Later I discovered they were poisonous and bitter-tasting. Then the deeper truth emerged: harmless Dismorphia had evolved to copy the bright warning colours of the Heliconius. These mimics, avoided by their natural enemies, survived to pass on their colours. Here was evolution by natural selection, written plainly on butterfly wings.

I published my paper in 1862, three years after Darwin's On the Origin of Species. That this "mimicry", discovered in remote jungles, could offer timely field support for his great theory remains my proudest achievement. They say I "wrote the book" on field study. I simply followed my fascination, one find at a time, from my father's Leicester workshop into the heart of nature's grandest design.
