Changing technology stimulates (刺激) the brain and increases intelligence. But that may only be true if the technology challenges us. In a world run by intelligent machines, our lives could get a lot simpler. Would that make us less intelligent?

    After the Industrial Revolution, machines began to replace manual workers. The process played out in agriculture as well as manufacturing so that groups of agricultural workers were replaced and forced to move to cities to make a living.

    When machines took away much of the manual work, people became less physically active and gained weight. The sedentary (久坐的) lifestyle contributed to a worldwide spreading of overweight and related metabolic disorders such as heart disease, secondary diabetes and kidney disease .

    As our bodies rested, our brains were forced to work harder, however. It is much more difficult to drive through an overcrowded modern city than it is to move around in a small rural village, for instance. Modern jobs are also more complex and urgent and they require more education because employees need to process new information quickly. Even during our leisure time, our brains work harder due to greater availability of books and explosion of audiovisual media, for entertainment, study, music, news, and so forth.

    Now in the Internet age, the amount of information grows fast along with the advance of electronic technologies. The number of people with whom we interact electronically grows by leaps and bounds thanks to the ease of use of social media like Facebook and Twitter.

    All of this extra work for our brains makes us more intelligent. That helps explain why human intelligence increases steadily from generation to generation in all developed countries, a phenomenon named the Flynn Effect. Of course, there are other reasons, including improved nutrition, better medical practices that reduce brain damage, and improved sanitation and public health that reduce diseases of childhood.

    In the P.G Wodehouse novels, Bertie Wooster got away with being a fool because Jeeves was there to back him up with superior brain power. Similarly, people of the future are at risk of being less intelligent because machines will do their thinking for them.

    Artificial intelligence is taking over many human jobs. For instance, planes are being flown much of the time by automatic pilots. Moreover, the complex problem of controlling air traffic around large modern airports is also achieved by artificial intelligence that operates well beyond the capability of mere human air traffic controllers.

    Artificial intelligence exists in many fields of modern life for the simple reason that intelligent machines can already outperform humans, including some aptitudes (天资) which were once thought to be a human advantage, such as playing chess or recalling details in a game of Jeopardy.

    Machine intelligence is increasing much faster than human intelligence. As machines get smarter, they will do more of our thinking for us and make life easier.

    Instead of struggling to identify ourselves to some electronic system via passwords that are secure only if they are hard to remember, the system will work harder to identify us using biometrics (生物测定学) such as fingerprints or even the individual sound of our hearts. More technologies of the future may also be voice-activated so that we will talk with machines much as we would talk to a friend.

    In the future, the electronic assistant will develop to the point where it serves similar functions as a real living chief male servant of a house, fulfilling requests such as: “Organize a dinner party for six on Thursday, Jeeves, and invite the usual guests .”

    At that point, our long struggle with challenging technologies is at an end. Like Bertie Wooster, we can take it easy knowing that the hard work of planning and organizing is being done by a better brain—the electronic assistant. Starved of mental effort, our brains will return to an earlier or less advanced form.

    The future is still in the fog.

    The medical world is gradually realizing that the quality of the environment in hospitals may play an important role in helping patients to get better.

    As part of nationwide effort in Britain to bring art out of the museum and into public places, some of the country's best artists have been called in to change older hospitals and to soften the hard edges of modern buildings.

    Of the 2,500 national health service hospitals in Britain, almost 100 now have very valuable collections of present art in passages (走廊), waiting areas and treatment rooms.

    These recent movements first started by one artist, Peter Senior, who set up his studio at a Manchester hospital in northeastern England during the early 1970s. He felt the artist had lost his place in modern society, and that art should be enjoyed by a wider audience. A common hospital waiting room might have as many as 5,000 visitors each week. What a better place to hold regular exhibition of art! Senior held the first exhibition of his own paintings in the outpatients waiting area of the Manchester Royal Hospital in 1975. Believed to be Britain's first hospital artist, Senior was so much in demand that a team of six young art school graduates soon joined him.

    The effect is surprising. Now in the passages and waiting rooms, the visitor experiences a full view of fresh colors, playful images and restful courtyards.

    The quality of the environment may reduce the need for expensive drugs when a patient is recovering from illness. A study has shown that patients who had a view onto garden needed half the number of strong painkillers compared with patients who had no view at all or only a brick wall to look at.

    Elephants are able to know the difference between a man and a woman, and can tell an adult (成年人) from a child—all from the sound of a human voice. This is according to a study in which researchers played voice recordings to wild African elephants.

    The animals showed more fear when they heard the voices of adult Masai men. Usually Masai people hunt elephants, and this suggests that animals have grown to listen for and avoid them.

    Prof. Karen McComb and Dr Graeme Shannon from the University of Sussex led the study. They explained that in former research they had used similar experiments to show that elephants could tell—from the sound of a lion—whether the animal was a female (雌性) or a more dangerous male (雄性).

    Prof  McComb wanted to find out if the animals used their very sharp sense of hearing to recognize danger from humans.

    The scientists recorded Masai men, women and children saying, in their own language, "Look, look over there, a group of elephants are coming." They also recorded Kamba men saying this phrase.

    Masai people often come across elephants, which can result in violent (暴力的) hunting. Kamba people, however, mainly feed on agriculture, which does not generally bring them into violent touch with the animals.

    When the team played recordings of these different voices through a hidden speaker, they found that elephant family groups showed more fear in response to the voice of a Masai man, than to a Kamba man's voice. And the adult male Masai voices caused far more violent response than the voices of women or boys.

    If you rent an apartment in Beijing, you also rent the landlord or landlady for at least a year. It's important you find a good match because you have to deal with them in the long term. For me, it was love at first sight with the elderly couple who owns my apartment.

    It was quite a tough trying to find the right apartment when I first arrived in Beijing. The apartments were either unsuitable or I find fault with the owners who looked indifferent at best and unfriendly at worst. But that all changed when the renting agent's car stopped in front of a hutong house in the heart of the capital.

    I saw an elderly couple, in their 70s perhaps, waving to me. They were warm and welcoming at first glance, and when I saw them attentively hanging up the curtains in what would become my bedroom, I was just about sold on the place and the owners!

    Chinese people talk about yuanfen, meaning fate that brings people together. Before I met my current landlords, I thought the concept of yuanfen was overrated. A generous landlady who liked me and wanted me to move into her apartment had used the term in reference to me. But it was this lovely couple that changed my mind about the concept.

    We have become accustomed to visiting each other at home. The couple's apartment is lovingly decorated, boasting a recent wedding photo of themselves taken in bridal wear. The landlord likes to smoke and sip tea, while the landlady takes great pride in her appearance.

    After three years, I dare say they treat me a bit like a "daughter", despite having two grown sons, one of them close by. They give me gifts of tea or clothes, and I bring them souvenirs from my trips. A match made in heaven, indeed!

    It is true that summer is hot. But here is something to make your day easier. Are you prepared? Meet the new AirFreez— an alternative to traditional Air Conditioners that cools you just the same!

    How does it work?

    It is surprisingly easy to set up! You just need to plug it into a socket(插座)OR any USB port (it uses so little energy that it can even run off of a phone or laptop battery).

    Once you have done that, simply fill it with 20oz/0. 6L of cold tap water.

    Now just press the power button and the instant cool air is here!

    What is so special about this little box?

    It is no larger than a lunchbox. It can be powered by a pocket solar panel（电池板）or battery pack and you probably have the world's first and most portable AC unit.

    Bad sleepers are putting the AirFreez next to their beds at night. The relaxing blow of cool, clean air, the comforting soft night light and the quiet create the perfect sleeping conditions!

    The price is just amazing. Most AC units cost at least $ 300+ AND you have to pay more to cover the expensive electricity bills each month. AirFreez costs less than $ 100 (actually $ 53 if you buy more than one here).

    Top Tips:

    To make your air even cooler—add a bottle of cold tap water from your refrigerator or even ice!

    For a beautiful relaxing atmosphere—add a few drops of fragrant oils to the water!
