What will our future look like? People have always been wondering about this question. Go on reading this text and you will know what will happen in the next fifty years.

    How can we know what the future will look like? To be able to understand the future, you must know the past. What has taken us to where we are today and what has changed along the way? The world has changed a lot in the last 150 years, but we humans are driven by the same basic needs as we were 150 years ago. Will this change in the next 150 years? No.

    What inventions have really made a difference in the last 150 years? In the past years, the inventions that have affected most people around the world for everyday living are the telephone, electricity, radio, television, computer, the car and the ability to communicate through the Internet. Then we of course have a lot of inventions that have made life easier, like new medicine, faster transports etc. In general, human beings have been working hard in the last 150 years to make the inventions so that they will be able to get control of the time and the world. Since there is still much to do in this area, this will be the focus at least for the next 150 years.

    Why do we need to predict the future? Predicting the future is important for two reasons: first we need to start to think about what kind of what kind of future we would like for ourselves and to pass on to the next generation, and then we need to know what decisions we need to make today that will give the best result in the future.

Do you think you would work out more if you were offered money to do so? Science has shown that money can give people motivation to work out, but perhaps not in the way that you think.

According to a study published in the Annals of Internal Medicine Journal, the best strategy isn't offering money; it's giving someone money, then threatening to take it away.

Researchers gave 281 people the goal of walking 7,000 steps every day over 13 weeks.

To motivate the people who took part to reach the goal, researchers divided them into three groups.

People in the first group received $1.40(9 yuan) each day as long as they finished 7,000 steps, the second group was only able to collect the $1.40 if they had reached 7,000 steps the day before, and the third group was given $42 at the beginning of each month and $1.40 was taken away every time someone failed to meet the goal.

The third group met their daily fitness goals 50 percent more often than the other two groups, showing that people were most motivated to walk by the fear of losing money.

    “People are more motivated by losses than gains, and they like immediate gratification.” study author Dr Mitesh Patel, an assistant professor at the University of Pennsylvania in the US, told CNN. “They want to be rewarded today, not next year or far into the future.”

    Our brains tend to avoid wanting to lose things more than they try to get the benefits from gaining them, Patel explained. “It makes people think like the money is theirs to lose from day one.”

In addition, in most programs, many participants will drop out quickly and only the motivated will stay involved, Patel said.

    “In ours, we were pleasantly surprised that 96 percent stayed.” he added.

The study provides evidence that what matters is not only the money incentive （激励）, but also how you think about them. This is important to how effective they are. The evidence could have a big effect on health promotion programs in the future, according to the study.

“Incentives themselves are not all you need,” Stephanie Pronk, a health and wellness consultant with the Aonplc corporation, told The Wall Street Journal. “It's really important to change up the incentive design and keep people on their toes.”

    “Heaven (天堂) is where the police are English, the cooks are French, the mechanics are German, the lovers are Italian and everything is organized by the Swiss. Hell (地狱) is where the police are German, the cooks are English, the mechanics are French, the lovers are Swiss, and everything is organized by the Italians.”

    Obviously the national stereotypes (模式化的思想) in this old joke are generalizations (普遍化), but such stereotypes are often said to “exist for a reason”. Is there actually a sliver (裂片) of truth in them? Not likely, an international research team now says.

    “National and cultural stereotypes do play an important role in how people see themselves and others, and being aware that these are not dependable is a useful thing,” said study author Robert McCrae of the National Institute on Aging. “These are in fact unfounded stereotypes. They don't come from looking around you,” McCrae said.

    If national stereotypes aren't rooted in real experiences, then where do they come from? One possibility is that they reflect national values, which may become known from historical events. For example, many historians have argued that the spirit of American individualism (个人主义) has its origins in the experiences of the pioneers on the Old West.

    Social scientists such as psychologist Richard Robins have given several other possible explanations for stereotypes and why they may be incorrect. Robins notes that some stereotypes may have been correct at one point in history and then remained unchanged while the culture changed.

    We may be “hard-wired”, to some degree, to keep incorrect stereotypes, since we are less likely to notice and remember information that is different from our stereotypes. Generally, according to Robins, when we meet people who are different from our stereotypes, we see them as unique individuals rather than typical national or cultural groups.

    In no particular order, here are some songs on the Music app of my phone:

On a Sunday Afternoon by Lighter Shade of Brown— A student of mine introduced this rap song to me all the way back in the early 1990s, when I was teaching Spanish at a local university. The story in the song takes place not too far from where I live in Los Angeles. It's a good "driving" song, nothing difficult or "deep".

Say Something by A Great Big World—A more recent song about a couple losing contact with each other. The piano part is of very little playing but beautiful.

    The Weight by The Band — Another old song, originally made public in 1968, but one I didn't hear until I was in high school more than 10 years later. I don't understand the words to the song completely, but the feeling of the song is very comforting to me.

Under the Bridge by Red Hot Chili Peppers — This Los Angeles group wrote a song that I used to listen to when I first moved to LA more than 25 years ago. I didn't know anyone here when I first arrived. When I got bored, I used to drive up and down the major streets that cross the city from east to west, listening to this song about t4the city of angels" being as "lonely as I am" (Don't worry. I have plenty of friends now.)

    If you have a chance to go to Finland, you will probably be surprised to find how "foolish" the Finnish people are.

    Take the taxi drivers for example. Taxis in Finland are mostly high-class Benz with a fare of two US dollars a kilometer. You can go anywhere in one, tell the driver to drop you at any place, say that you have some business to attend to, and then walk off without paying your fare. The driver would not show the least sign of anxiety.

    The dining rooms in all big hotels not only serve their guests, but also serve outside diners. Hotel guests have their meals free, so they naturally go to the free dining rooms to have their meals. The most they would do to show their good faith is to wave their registration card to the waiter. With such a loose check, you can easily use any old registration card to take a couple of friends to dine free of charge.

The Finnish workers are paid by the hour. They are very much on their own as soon as they have agreed with the boss on the rate. From then on they just say how many hours they have worked and they will be paid accordingly.

    With so many loopholes in everyday life, surely Finland must be a heaven to those who love to take "petty advantages". But the strange thing is, all the taxi passengers would always come back to pay their fare after they have attended to their business; not a single outsider has ever been found in the free hotel dining rooms. And workers always give an honest account of the exact hours they put in. As the Finns always act on good faith in everything they do, living in such a society has turned everyone into a real "gentleman".

    In 2011, the old style Malta buses were taken off the road and replaced by modern vehicles. Most of the old buses were deserted, a few were sold, and about 100 of them were put into storage in the hope of showing them in a museum at some stage.

    A pre-2011 visit to Malta wouldn't have been complete without a ride on one of the colorful buses. Until 1973 you could tell the destination of the bus just by looking at its color — Sliema was green and white, Zabbar was red and white with a blue stripe(条纹)etc. . Later, the buses all had numbers. For a while, they were all painted green and white before the ‘final' orange, yellow and white.

    In their prime, walking around the Triton fountain at the Valletta bus station, you would have found it very difficult to see two buses of exactly the same design. Most of them had locally built bodies. On the front of the buses carried names like Dodge, Leyland, Bedford etc. You were equally likely to find football pennants(锦旗)and the like decorating the cabs. Real bus experts would have recognized that these were there mainly for decorative reasons, and were seldom an accurate reflection of the vehicle's origins.

    Nowadays much more modern buses are to be found at the Floriana bus station. They are more environmentally friendly and possibly even more comfortable than the older types. However, I miss the old buses. I remember, when you boarded your bus, you had to prepare the correct change to pay the usually bad-tempered driver as you got on. If you were seated anywhere near the front, you would have noticed that most drivers sat well to the right of their steering wheel. The reason for this, as any Maltese would tell you, was to leave space for their pet to sit alongside them. I wonder where the pet sits these days.
