China is a land of bicycles. At least it was back in 1992 when I traveled the country. Back then everyone seemed to be riding a bicycle. Millions of them, all black. Cars were rare. Yet since my arrival in Beijing last year, I've found the opposite is true. There are millions of cars. However, people still use their bicycles to get around. For many, it's the easiest and cheapest way to travel today. Bicycles also come in different colors — silver, green, red, blue, yellow, whatever you want.

    It's fun watching people biking. They rush quickly through crossroads, move skillfully through traffic, and ride even on sidewalks. Bicycles allow people the freedom to move about that cars just can't provide.

    Eager to be part of this aspect of Chinese culture, I decided to buy a bicycle. Great weather accompanied my great buy. I immediately jumped up on my bicycle seat and started home.

    My first ride home was orderly (守秩序的). To be safe, I stayed with a “pack” of bikers while cars on the streets came running swiftly out of nowhere at times. I didn't want to get hit. So I took the ride carefully.

    Crossing the streets was the biggest problem. It was a lot like crossing a major highway back in the United States. The streets here were wide, so crossing took time, skill and a little bit of luck.

    I finally made it home. The feeling on the bicycle was amazing. The air hitting my face and going through my hair was wonderful. I was sitting on top of the world as I passed by places and people. Biking made me feel alive.

    This four-day festival displays the latest exciting gadgets(小机械) and introduces their inventors. Visitors can explore electronics(电子产品), build robots, get hands-on with new technologies and have a go at 3D printing. There will be displays taking place throughout the festival, which is suitable for anyone aged ten and over.

    Imagine you went to a restaurant with a date, had a burger, paid with a credit card, and left. The next time you go there, the waiter or waitress, armed with your profile data, greets you with, "Hey Joe, how are you? Mary is over there in the seat you sat in last time. Would you like to join her for dinner again?" Then you find out that your burger has been cooked and your drink is on the table. Forget the fact that you are with another date and are on a diet that doesn't include burgers. Sound a little odd? To some, it is the same with the Internet. The Nets ability to profile you through your visits to and interactions at websites provides marketers with an enormous amount of data on you--some of which you may not want them to have.

    Are you aware that almost every time you access a website you get a "cookie"? Unfortunately, it's not the Mrs.

    Reid's type. A cookie on the Internet is a computer code sent by the site to your computer--usually without your knowledge. During the entire period of time that you are at the site, the cookie is collecting information about your interaction, including where you visit, how long you stay there. How frequently you return to certain pages, and even your electronic address. Fill out a survey to collect free information or samples, and marketers know even more about you--like your name, address, and any other information you provide. While this may sound scary enough, cookies aren't even the latest in technology. A new system called I-librarian Alexa--named for the legendary third century.

    B. C. library in Alexandria, Egypt--does even more. While cookies track what you are doing at one site, Alexa collects data on all your Web activity, such as which sites you visit next, how long you stay there, whether you click on ads, etc. All this information is available to marketers, who use it to market more effectively to you. Not only do you not get paid for providing the information, you probably don't even know that you are giving it.

    There has long been a notion （观念） that money buys happiness. However, although "we really, really tried that for a couple of generations, it didn't work," said Francine Jay, author of The Joy of Less, A Minimalist Living Guide: How to Declutter, Organize, and Simplify Your Life.

    Thanks to a travel inspired revelation （启发）, Jay has been happily living a simpler life for 12 years. "I always packed as lightly as possible, and found it exciting to get by with just a small carry on bag," she told CNN. "I thought if it feels this great to travel lightly, how amazing would it be to live this way？ I wanted to have that same feeling of freedom in my everyday life."

Jay decided to get rid of all her excess （额外的） possessions and live with just the essentials （必需品）. "I wanted to spend my time and energy on experiences, rather than things."

    Jay is a follower of a movement called "minimalism （极简主义）". Growing numbers of people have been attracted to this lifestyle all over the world. They share the same feeling of disappointment with modern life and a desire to live more simply. Minimalists are typically progressive and concerned about the environment, Leah Watkins, a lead researcher at Ota go University in New Zealand, told Stuff magazine in March.

    But many simply experienced unhappiness caused by owning too many possessions. Depression with the materialism of our world isn't new. English romantic poet William Wordsworth summed up how dispiriting （令人消沉的） this was back in 1802, at the beginning of the industrial age, when he wrote: "Getting and spending, we lay waste our powers". His preference was to go back to nature. Closer to our own times, the hippies （嬉皮士） of the 1960s also sought to "drop out" of modern life.

    And for many minimalists, their key is to unload. Without objects, they "believe people are forced more and more into the present moment and that's where life happens," wrote Stuff.

But does simplicity ever feel like a sacrifice （牺牲）？

    "It's eliminating the excess﹣unused items, unnecessary purchases﹣from your life. Well, I may have fewer possessions, but I have more space …Minimalism is making room for what matters most," said Jay.

    And "the real questions", according to Duane Elgin, US social scientist, are "what do you care about？" and "What do you value?"

    He told CNN: "It's important for people to realize minimalism isn't simply the amount of stuff we consume. It's about our families, our work, our connection with the larger world, our spiritual dimension. It's about how we touch the whole world. It's a way of life."

    Who cares if people think wrongly that the Internet has had more important influences than the washing machine? Why does it matter that people are more impressed by the most recent changes?

    It would not matter if these misjudgments were just a matter of people's opinions. However, they have real impacts, as they result in misguided use of scarce resources.

    The fascination with the ICT (Information and Communication Technology) revolution, represented by the Internet, has made some rich countries wrongly conclude that making things is so "yesterday" that they should try to live on ideas. This belief in "post-industrial society" has led those countries to neglect their manufacturing sector (制造业) with negative consequences for their economies.

    Even more worryingly, the fascination with the Internet by people in rich countries has moved the international community to worry about the "digital divide" between the rich countries and the poor countries. This has led companies and individuals to donate money to developing countries to buy computer equipment and Internet facilities. The question, however, is whether this is what the developing countries need the most. Perhaps giving money for those less fashionable things such as digging wells, extending electricity networks and making more affordable washing machines would have improved people's lives more than giving every child a laptop computer or setting up Internet centres in rural villages, I am not saying that those things are necessarily more important, but many donators have rushed into fancy programmes without carefully assessing the relative long-term costs and benefits of alternative uses of their money.

    In yet another example, a fascination with the new has led people to believe that the recent changes in the technologies of communications and transportation are so revolutionary that now we live in a "borderless world". As a result, in the last twenty years or so, many people have come to believe that whatever change is happening today is the result of great technological progress, going against which will be like trying to turn the clock back. Believing in such a world, many governments have put an end to some of the very necessary regulations on cross-border flows of capital, labour and goods, with poor results.

    Understanding technological trends is very important for correctly designing economic policies, both at the national and the international levels, and for making the right career choices at the individual level. However, our fascination with the latest, and our under valuation of what has already become common, can, and has, led us in all sorts of wrong directions.

Let's face it. No one drinks diet sodas for the taste. People drink diet sodas in the hope that it will help them lose weight or at least keep them from gaining it. Yet it seems to have exactly the opposite effect, according to a new study.

Researchers from the University of Texas said those who drank two or more diet sodas a day had waist size increases that were six times greater than those who didn't drink diet sodas. "What we saw was that the more diet sodas a person drank, the more weight they were likely to gain," said Sharon Fowler.

The study was based on data from 474 participants in a large, ongoing research project, where the participants were followed for nearly 10 years.

While the findings are surprising, they also offer some explanations.

Nutrition expert, Melanie Rogers, who works with overweight patients in New York, has found that when patients are switched from regular to diet sodas, they don't lose weight at all. "We weren't seeing weight loss necessarily, and that was confusing to us," said Rogers.

So why would diet soda cause weight gain？No one knows for sure yet, but it could be that people think they can eat more if they drink diet sodas, and so over﹣compensate (补偿) for the missing calories.

A related study found some sweeteners (甜味剂) raised blood sugar levels in some mice. "Data from this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be risky," said Helen P. Hazuda, professor at the University of Texas's school of medicine." They may be free of calories, but not of consequences. "
