We've reached a strange—some would say unusual—point. While fighting world hunger continues to be the matter of vital importance according to a recent report from the World Health Organization (WHO), more people now die from being overweight, or say, from being extremely fat, than from being underweight. It's the good life that's more likely to kill us these days.

Worse, nearly 18 million children under the age of five around the world are estimated to be overweight. What's going on?

    We really don't have many excuses for our weight problems. The dangers of the problem have been drilled into us by public ­health campaigns since 2001 and the message is getting through—up to a point.

    In the 1970s, Finland, for example, had the highest rate of heart disease in the world and being overweight was its main cause. Not any more. A public ­health campaign has greatly reduced the number of heart disease deaths by 80 per cent over the past three decades.

    Maybe that explains why the percentage of people in Finland taking diet pills doubled between 2001 and 2005, and doctors even offer surgery of removing fat inside and change the shape of the body. That has become a sort of fashion. No wonder it ranks as the world's most body ­conscious country.

We know what we should be doing to lose weight—but actually doing it is another matter. By far the most popular excuse is not taking enough exercise. More than half of us admit we lack willpower.

    Others blame good food. They say: it's just too inviting and it makes them overeat. Still others lay the blame on the Americans, complaining that pounds have piled on thanks to eating too much American­ style fast food.

    Some also blame their parents—their genes. But unfortunately, the parents are wronged because they're normal in shape, or rather slim.

    It's a similar story around the world, although people are relatively unlikely to have tried to lose weight. Parents are eager to see their kids shape up. Do as I say—not as I do.

    A new report from the International Bar Association (IBA) suggests machines will mostly likely replace humans in a growing number of occupations. One of the authors of the report, Gerlind Wisskirchen, believes that governments need to introduce human quotas（配额）in some sectors in order to protect jobs.

    The report suggests that the jobs at risk are common ones, such as accountants and lawyers. Financial services are more at risk than legal roles though, as algorithms（计算机程序）are easier for a computer to solve when compared to keeping client relationships and making new laws. Simple physical work is also in the firing line, the authors mention.

    As the world population heads toward 7 to 10 billion, futurist Morris Miselowski says, “I am not sure that this nine-to-five, Monday to Friday work as we understand it, will continue for many of us for the next couple of decades.” He forecasts that the biggest changes will be a shift（转变）away from the traditional work time..

“Artificial intelligence (AI)（人工智能）… and all sorts of new technologies are just about to happen; all of that's going to change where, how and when we do work.”

Ms Wissfikirchen was surprised by how far-reaching the effects of automation（自动化）are.

     “Even though automation began 30 years ago in the blue-collar sector, the new development of artificial intelligence and robotics affects not just the blue-collar sector, but the white-collar sector,” said Ms Wisskirchen.

    Toby Walsh, professor of Artificial Intelligence at UNSW, said there was a ray of hope when it came to technology and the future of jobs.

“It's always good to remember that although technology will take jobs away as they raise in this report, there will also be new jobs created by technology,” he said. “In fact if we look at the history of technology since the Industrial Revolution, more jobs have been created than destroyed.”

    Often people receive a guitar, mandolin, or some other musical instrument as a birthday or Christmas gift. There's joy everywhere. The giver of the gift knows how much the receiver wants to learn this instrument and the receiver is actually holding it in his hands instead of longing for it through the shop window.

    Finding an instructor that fits into a busy work schedule is hard enough, but once you decide on a lesson plan, then you must consider the practice time, how to practice, what to practice—and let's face it...not all people learn something the same way. So in order to learn a musical instrument, how much practice time is enough and what kind of practice is right for you?

    There is no set amount of time that anyone should practice a musical instrument. When I was in programming classes, I could have studied nightly for 5 hours each night. It would have taken me years to learn the art of computer programming. Though I'm attracted by the systematic logic of it, my talent is towards another thing. However, on the other hand, if I spent an hour every couple days with a passionate hobby like playing the violin, not only would the time fly quickly...I'd also be learning at a much greater speed since the built-in passion is the motivation for advancement.

    So as much as it's important to practice, a step back is to first find the harmonious instrument that fits you as a person; as development of your personality. If you're learning the guitar because it's cool....obviously that's the modern-day mindset, however, you might not be actually linking your talent for musical satisfaction with your most creative advantages you have to offer.

    It's been my experience that every person has a certain level of musical talent. My pleasant challenge has been to assist them in this adventure and actually locate their best abilities as quickly as possible. Then and only then can we match learners with instruments and truly begin a fun and exciting walk down the road of happiness and contentment, where music, ability, personality and soul all meet. Once this piece of the mystery puzzle is in place, I've never had to work at motivating a learner to practice...

Do you believe that things are connected for no scientific reason at all? For example, do you avoid saying the word "four" to avoid bad luck? If so, you have a superstition (迷信). And you're not alone — all kinds of people have them.

For example, Portugal's soccer superstar Cristiano Ronaldo always steps onto the pitch (球场) with his right foot first, according to The Telegraph. And sports players are not alone in having superstitions. A visitor once asked the Nobel Prize winning scientist Niels Bohr whether he really believed that the horseshoe he'd hung at his country home was lucky. "Of course not," the Danish physicist said. "But I understand it's lucky whether you believe in it or not."

One recent study found that even scientists at MIT and other top US schools tended to look for a meaning in natural events, similar to the connection between stepping on the pitch and playing soccer well, according to The Atlantic. When the researchers gave the scientists little time to answer questions, they were twice as likely to agree with statements such as "Trees produce oxygen so that animals can breathe" as they were when they had more time to think about their reply.

It seems that fear can make people think differently in this way, too. In a British study, students imagined meeting a "witch" who said she would cast (施魔法) an evil spell(符咒) on them. About half said a scientist should not be worried about the spell. Yet each of them said that, personally, they wouldn't let the witch do it to them.

So why are so many of us superstitious? Well, it seems to be our way of dealing with the unknown. "Many people quite simply just want to believe," Brian Cronk, a professor of psychology at Missouri Western State University, said in a 2008 interview. "The human brain is always trying to work out why things happen, and when the reason is not clear, we tend to make up some pretty bizarre (古怪的) explanations."

    And these explanations aren't completely unhelpful. In fact, superstitions can sometimes work and bring real luck, according to psychologists at the University of Cologne in Germany in the May 2010 issue of the journal Psychological Science. They found that believing in something can improve performance on a task like an exam.

    So, what about you? What superstitions do you follow to keep you safe and successful?

    83-year-old Antonio Vicente has spent the last four decades of his life fighting against the current. As Brazilian landowners cut down rainforests to make room for profitable (盈利的) plantations and cattle grazing grounds, he struggled to bring the thick jungles of his childhood back to life.

    In 1973 Antonio took up the challenge of restoring the forest on a 31-hectare piece of land that had been destroyed for cattle grazing. Ironically enough, he bought the land in Brazil's Sao Paulo region, using credits（贷款）that the military government was giving out to promote deforestation(砍伐森林) and agricultural technology. But Antonio didn't use the money to promote the national agriculture but wanted to revive the forest.

    "You are stupid. Planting trees is a waste of land. You won't have income. If it's full of trees, you won't have room for cows or crops," Antonio's neighbors told him. But he knew the damage caused by deforestation was far greater than financial profit. Antonio had grown up on a rural farm, and watched his father and the other villagers cut down forests at the owners' orders, either for charcoal production or to clear land for grazing cattle. He had watched the ancient water sources dry up and people struggling to survive.

    With only some donkeys and a few hired workers Antonio brought back the forest to his land. What started out as a weekend hobby soon became a permanent way of life. Antonio often recalls spending days and nights in his young jungle, surrounded by rats and foxes, and eating banana for breakfast, lunch and dinner.

    As the forest grew, the water returned, and Antonio says that there are now over 20 water sources on his land that were no longer there when he bought it. Then the animals started making a home there. Today, the forest is alive with sounds of birds and insects living there, and more species are settling in every year.
