Last night, on my way home I stopped because of being attracted by some hamburgers at a fast food restaurant. On my way in, a homeless man approached me and asked, “Do you have any bottles lying around?” I knew he would recycle them for a few cents, but I didn't have any, so I said no. And again he asked, “Can you spare some change ?” I smiled, and said no again. He was very respectful; he smiled back and said, “OK, thank you.” Even though he didn't have anything, he was still in good spirits. From the way he spoke I could tell he was smart.

    Then I bought one hamburger and enjoyed my meal, but in the back of my mind I wondered whether the homeless man was hungry. After I finished my meal I decided to order another one for him. At this point I didn't know if he was still around, but I tried anyway.

    At the counter I ordered a hamburger and also a hot chocolate, because it was cold outside, and I thought it would help warm him up. They delivered me the hot chocolate first and as I waited for my hamburger, I noticed the homeless man was standing right beside me. I looked at him and smiled, “This hot chocolate is for you.” He replied like a gentleman, “Thank you so much. That's very kind of you.”

    I always believe no matter how hard up I am, there are always those who are worse off than I. When you help someone, it's not always about money, it's about love. The love you give today, someone might forget tomorrow. It doesn't matter. Love anyway, because the greatest thing you can give is love.

    What do we think of when we someone mentions Scandinavia(斯堪的纳维亚半岛), the group of Northern European countries? Many things come to mind. We might think of the breath-taking natural beauty of Norway's fjords(海湾). If we enjoyed the fairy tales of Han Christian Anderson as children, perhaps we will think of  Denmark's capital, Copenhagen, and its statue of Anderson's Little Mermaid（美人鱼）.

    Perhaps we shiver at the thought of Scandinavia, as the countries there can be very cold. Or maybe we imagine this part of the world, so high up in the Northern Hemisphere, as dark and a little gloomy.

    What doesn't come to mind is people who like to party. However, according to a survey released by travel site Hostel-world this month, Scandinavia has some of the most sociable cities on the planet.

    For the study, 12,188 people from cities around the world were asked about their attitudes to socializing. Overall, Gothenburg in Sweden came out on top, but Copenhagen and Stockholm also placed highly, among with more predictably lively cities like New York and Madrid.

    A city made up of many little islands, Gothenburg is, according to The Daily Telegraph, "charming in an old-fashioned way". The city's authorities have preserved Gothenburg's attractive wooden houses from the 19^th century. Many of these have been made over into restaurant and coffee bars. Music fans are as well satisfied too — Gothenburg has dozens of record stores and live music venues(场所).

    As you'd expect, Scandinavia cities are also welcoming to visitors. People here don't care about your cultural background or anything else that some other places might take exception to. In these friendly Scandinavia cities, everyone's invited to the party.

    A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

    "It's extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件)," said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. "The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own," he said.

    They engineered a series of systems to start and drive the robotic fly. "The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it's connected to," said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.

    While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers' fields or on the battlefield. "Basically it should be able to take off, land and fly around," he said.

    Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. "You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead," he said. "So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis."

    If you love eating and drinking for free and are looking to make some pocket money, there's a job in China with your name on it. A new type of online service allows people to hire others either to eat or drink their favorite treats or satisfy their appetite without the calories that usually come with it.

    Chinese media recently reported on an increasingly popular service on online platform Taobao that's as startling as it is appealing. People can now go online and hire others to consume certain foods and drinks, and ask them to provide video evidence of them eating or drinking the said treats.

    Fees usually range from two to nine yuan ($0.30 - $1.35) plus the cost of the food. It's not exactly a get-rich-quick job, but there are quite a lot of people willing to do it for the free treats alone.

    "Bubble tea drinking" is a particularly popular service, as the chewy tapioca(木薯粉) balls and popping drink is all the rage in Asia these days, but there are also ads from people willing to eat fried chicken or hot pot for anyone willing to pay for them.

    Advertised as being "fat-free" and "free of queues", those who pay for the service will receive the full experience, which includes a 360-degree video of the drink, photos, and a detailed description. Prices of the service are based on the drink's sweetness level, its price, and popularity. Some clients even require a short written review to be sure that the person they hired actually does what they are supposed to.

    Sellers explained that most customers buy their "Bubble tea drinking" service maybe because they're trying to shake off desires while they're on a diet. Drinking bubble tea by proxy may help customers avoid high blood pressure, high blood sugar, and other health problems that the sugar-laden drink may cause.

    So why would anyone pay a total stranger to enjoy a treat rather than consume it themselves? Well, apparently, the online service is so cheap that some people simply do it out of boredom, while others get satisfaction from watching others indulge in their favorite treats.

    This indulging-by-proxy service(代享受服务)has received a lot of attention on social media in China, with some people describing it as the job of their dreams.

Photo Research

"If you want to be a better photographer, stand in front of better stuff." Photographer Jim Richardson shared it with others. He spends a great deal of time doing photo research, looking for great locations to shoot.

Seeing a wonderful place is bread-and-butter photography—it's just part of the job. Getting there is only half of any great photograph's story. The other half is how the photographer prepares to capture the subject once in front of it. It is believed that groundwork is part of photography, as essential as knowing exposure and lighting or recognizing the decisive moment to take the shot. Research sounds like a boring task for many photographers, while for others digging into a subject in advance is part of the pleasure.

Philosophically, photographers seem to divide along that line. On one side are those who desire only to be in the moment. On the other side are the planners. They would never dream of going out the door without a full list of how they're going to approach the shoot. Actually, there is a third group nowadays. They just take photos of the whole scene and do all the creative work in Photoshop after the event. Most photographers do both: research carefully to prepare their schedule and then act in the moment once on site.

Photographers should do a lot of research in order to get ready for a photographic trip. This includes creating a file for each location they are due to visit. They start a file for each place and begin to make a list of the pieces of information. Knowing what the place looks like in advance is invaluable, so it is good to hit several Internet photo sites. Besides clueing them into the photographic possibilities of the location, this can also show what angles have already become overused and which they should therefore avoid. But photographers will also find angles they didn't expect from locations they hadn't imagined. Armed with these they will be better prepared to push the boundaries of what they expect.

"Above all, I'll look for places and events that are seasonal and timeless. I open my mind to what might make a great subject for a picture," Jim said. "Most travelers tend to think only of places they're visiting, without looking deeper into culture, history or meaning. I try to get in time with the rhythm of the place and in tune with its melody. But most of all I just want to be ready. If I'm ready, I can just about count on being lucky."

Every year, some 2. 3 million women and men around the world died from work-related accidents or diseases—that's more than 8, 000 deaths every single day—and at least 402 million people suffer from non-fatal occupational injuries. The number is enormous in terms of personal tragedy and hardship. And it comes with a huge economic loss. It is estimated that occupational accidents and diseases lead to a 5. 4 percent loss of annual global GDP. 

A safe and healthy working environment is so important that in June 2022 the ILO (International Labor Organization) took a historic step when it added a safe and healthy working environment to its Fundamental Principles and Rights at Work. 

Why does this matter? It matters because occupational safety and health can now no longer be viewed as an optional extra. All of the ILO's 186 member states are now required to respect, promote and achieve a safe and healthy working environment as a fundamental principle and right at work. 

This is significant for several reasons. First, it recognizes that every worker has the right to be protected from dangers and risks that can cause injury, illness or death in the workplace. 

By making occupational safety and health (OSH) a fundamental right, the ILO is sending a clear message to governments and employers of all countries that they must take responsibility for providing a safe and healthy working environment for all workers. 

When workers feel safe and healthy in their workplace, they are likely to be more productive and efficient. This can benefit workers, employers as well as the economy. Conversely, when workers are injured or become ill due to workplace dangers, it can have a significantly negative impact on productivity and economic growth. 

A safe and healthy working environment is now a fundamental right for each and every worker. Governments employers, trade unions as well as companies must work together to make this right a reality.
