Forgiving(原谅) someone who has hurt you or let you down is never an easy thing. Several new studies, however, say that it could have a lot of health benefits. When you think of forgiveness, you probably don't think of it as being a health or medical problem. Studies from Stanford University, on the other hand, show that something like anger(愤怒) can change your well-being.

    When cartoon book characters like the Incredible Hulk get angry, they change colors and often gain special power. In the real world, anger is less obvious and may be more dangerous. That's why Professor Fred Luskin, founder of the Stanford Forgiveness Project and author of Forgive for Good, say holding on to anger and hatred(仇恨) can harm your physical and mental health. Two new studies seem to show the same idea. The studies find that people who are able to forgive feel less stress, less back pain, and less unhappiness. They also have fewer headaches, lower blood pressure and fewer problems on sleeping.

    So it doesn't matter if your anger is caused by the traffic or other things. Learning to let it go is important. Skills such as deep breath or thought can help. Or just ask yourself if it's worth hurting yourself by staying angry with someone else.

    Forgiveness doesn't mean that you simply accept what happened and say it's OK. Instead, it's a way of making peace with yourself about what happened in the past.

    The largest campaign of killing rats in history is set to poison millions of rats on the sub-Antarctic island of South Georgia. Scientists say the campaign planned for 2013 and 2014 will restore beautiful South Georgia to the position it once held as the world's most important nesting sites for seabirds.

    It was sailors in the late 18th century who unintentionally introduced rats to what had been a fresh environment. “If we can destroy the rats, at least 100 million birds will return to their home on South Georgia,” says Tony Martin, a biology professor at the University of Dundee who was invited to lead the project.

    South Georgia is by far the largest island to get rid of animals that destroy native wildlife after being introduced deliberately or accidentally by people. Though rats and mice have done the most damage, cats, foxes, goats, deer, rabbits and other species have been targeted in the campaigns around the world.

    South Georgia is seven times the size of New Zealand's Campbell Island, currently the largest area ever killing rats. The successful war against Campbell Island rats was carried out in 2001 with 132 tons of poison dropped from five helicopters.

    “New Zealand pioneered the techniques for ridding islands of rats and in fact our operation on South Georgia is based on New Zealand's technology.” Says Martin. “Some New Zealanders will be helping our campaign, including our chief pilot, Peter Garden, who was also chief pilot for the projects at Campbell Island and Rat Island, in the Aleutian chain of the north Pacific.”

    The second and third stages in 2013 and 2014 will involve dropping as much as 300 tons of poison from the air onto every part of the island where rats might live. It is a huge operation, carried out during the stormy southern autumn when the rats are hungry and the risks of poisoning native wildlife are less than in the spring and summer months. “Ideally we'd do in winter but the weather makes that too risky,” Martin says.

    The ecological payback will be priceless. But Martin says, “The full benefits will take decades to arrive, because some of these birds are slow to hatch.”

    Farah was sitting in the kitchen going over the party list with her mother. The exams were over and Farah wanted to invite her friends for a party.

    “Farah, aren't you going to invite Hafsa?” her mother asked. Hafsa had been her best friend since childhood.

    “Mother, you know I am now a part of Purple Girls Club and we have some rules about people we can be friends with,” Farah answered.

    “Really? And what are the rules?” her mother asked.

    “Well, only very pretty girls can be part of our group. And Hafsa is so, you know, dark.”

    “I cannot believe it.” her mother said angrily.

    As Farah left the kitchen, her father called her from the living room.

    Farah went to her father and paled when she saw the exam report in his hands.

    “Farah, what has happened to your grades? You have failed in Mathematics.” her father said.

    Farah had no answer. The truth was that the activities of Purple Girls Club left her with very little time for studies.

    “Farah, it says that you can take part in supplementary exams(补考). If your grades don't improve then, I'll cancel your trip to Spain.”

    Farah went to her room and called Gina, the leader of Purple Girls Club.

    “Gina, can you help me to complete my notes before the exams?”

    Gina laughed, “Exams? Who cares about exams?”

    One by one, she called her friends in the club but no one seemed to care or wanted to help. Farah knew Hafsa would help her. Farah also knew Hafsa had been hurt by her, but Hafsa said, “If you need any help, just let me know. We can study together till your exams.”

    Next Monday, as two friends entered the school together. Gina called out

    “Farah, you know our rules. You cannot be friends with those who do not belong to our club.”

    “Gina I have a new rule about friendship,” Farah replied.

    Reducing plastic waste isn't easy because the cheap material is found in almost every household item. Now, a delicious and nutritious solution has come up to help reduce our dependence on this environmental hazard.

    David Christian, the co-founder of Evoware, says the idea of creating the biodegradable (生物降解的) products came from concern at the country's high pollution rate. Indonesia is home to four of the world's worst polluted rivers. Since single-use packaging is a large contributor to the problem, Evoware decided to deal with that first.

    After investigating various materials, the company settled on seaweed. Unlike corn, commonly used for biodegradable containers, seaweed does not require resources like water or large amounts of space. Since Indonesian farmers already harvest more seaweed than they can sell, it's easy for the company to find the material.

    Though they will not reveal their production process, Evoware says the seaweed packaging contains no chemicals and is safe to consume. The company has also invented single-use cups, which can break down 30 days after they're thrown away.

    While replacing plastic with the seaweed products may seem appealing to most of us, it is a hard-sell in Indonesia. According to Christian, “The awareness to reduce single-use plastic is still very low. This makes our bioplastic unnecessary.” Also a factor is the cost, which is higher than using plastic. Hopefully, Evoware will succeed in convincing Indonesians and people worldwide that switching to their products will be helpful to protecting our beautiful planet.

    Can you imagine being paid millions for playing in a sports team? That you were able to fill stadiums with people coming to see you play? That you could attract fans crazily like a superstar? ESports have made all that possible and more. The fever for video games has had a great influence on the sports industry.

    To what degree ESports, or electronic sports can be considered a sport remains a question. If we stick to the meaning in the dictionary, sport is understood to be any physical activity, whether a game or competition, that requires training and following rules. A second meaning is: all kinds of physical activities are done for health or for fun.

    Spending hours and hours in front of a computer or with a mobile phone in hand playing video games is not a physical activity. But when the voices that defend it belong to famous athletes, and when the International Olympic Committee itself is, seriously thinking about the possibility of introducing eSports in the 2020 Olympic Games, it is at least worth considering the argument.

    It is clear that eSports has had a big influence on the sports industry and its fans are increasing all the time. Athletes, sports teams, sponsors （赞助商） inside and outside the sport, and the media support the industry greatly, which attracts and satisfies the young generation. Professional video game competitions have made nearly $900 million over the past three years thanks to sponsorship and advertising. The industry is expected to make over $1.1 billion and reach 215 million users in 2019, according to a study by the consultant Newzoo.

    The big players in the eSports leagues have turned their ‘hobby' into a profession which offers a chance to gain fame or become famous. Those guys who distance themselves from the world, shutting themselves up for up to 12 hours a day in a dark room to connect with people from all over the planet through a video game, now fill large stadiums and compete for prizes that are over one million dollars. They are the envy of half the planet!

    As a famous NBA superstar, Shaquille O'Neal says “the fans themselves are the ones who opened my eyes. ESports are a great business chance and the industry cannot be left out.”

    While millions of dollars are paid around the world for these new idols, we can continue to argue whether they are sports or not. If only for fun…

    Hobbies in general are becoming something of the past. Our lives are already filled with classes, homework, working, relationships and sleeping. When we do have a spare moment, it is all too easy to spend it on the endless entertainment and media that are right at our fingertips.

    I do not doubt that there are some people who could become a great writer or musician. I only fear that so many people are busy pursuing their education and their careers, but they never even see the potential (潜能) they have. The next great photographer or singer could be going to college right now. But they might not even know they have a gift for photographing or singing if they've never picked up a camera or a guitar.

    Of course, the final goal of pursuing a new hobby shouldn't be to become rich and famous. For most people, a hobby is just something they enjoy doing for the purpose of the thing itself. Such hobbies are still very useful. Studies have shown that people who have a hobby are less likely to have stress and more likely to have more meaningful lives.

    Most importantly, a hobby is just something you do to make you happy. I hate to break it to you, but we all have a long lifetime of work and stress ahead of us. It will make things much easier if we can practice the piano or make some collections after work.

    Sure, it's not easy to start a new hobby while going to school, but it will likely never get easier than it is right now. So think about the thing that you have always wanted to try but were too embarrassed or busy or whatever. You never know, you might become the world's next great people. If not, you'll at least be a little more well-rounded, more interesting and less stressed.
