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.

    How would you like to have been born without any ability to feel pain? There are such people. One of them is being studied by doctors at a hospital in New York City. He is a 22-year-old clerk who really does not know the meaning of pain. But he wishes he did.

    Not long ago a packet of matches flared up(骤然烧起) in his hand. Luckily the burn was not serious. It caused large blisters(水泡) but still did not bother him. He said the burn felt like a fly crawling(在……上爬行) on his fingers. It has been the same story as far back as he can remember. He has never had headaches or sore(疼痛的) muscles. Bee stings, cuts and bruises(疼痛的) do not hurt.

    Being free from pain is not as wonderful as you may think. The young man has had to have rotted teeth pulled because he never felt toothache warnings. A sudden attack of appendicitis(阑尾炎) could be deadly. Life without pain is as risky as trying to run a cruise ship without fire alarms.

    “I wish we hadn't come on this trip!” Jeff's voice echoed across the narrow canyon （峡谷）. His father stopped, breathing heavily. “This is hard on you, but you've got to come through with courage!” He gently placed his hand on the boy's shoulder. “Now, I don't know if I can make it without stopping every so often. You're young, but you're strong and fast. Do you remember the way back from here to the road, if you had to go alone?”

    Jeff flashed back to the painful scene of Mark, his seventeen-year-old brother at their campsite. He was bitten by a snake yesterday. This morning he couldn't move, and the pain got worse. He needed medical attention right away. They had left their phone in the car, and it must have been out of power by then. Leaving Mark at the campsite and seeking help was their only choice.

“Jeff, could you do it?”

    Jeff looked to the end of the canyon, several miles away. He nodded and a plan began to take hold in his mind. “What is the name of that little town we stopped, Dad?” There must be a hospital there.

    “Flint. We parked at the side of the road a few miles out of Flint.”

    Jeff nodded. Then they continued climbing. Stone by stone, they made their way up the canyon. Gradually, Jeff's father grew smaller and smaller in the distance. Jeff waved to him and then climbed toward the road. Two hours later, he finally reached the road and struggled toward the town, almost exhausted.

    “Can't stop.” He thought. “Mark's in big trouble. Keep going.” Suddenly, he saw a truck heading toward him. “Hey, mister!” He shouted, waving both arms. He began to jog toward the truck, and then broke into a full-speed run.

    His chest was burning with every breath when the truck driver stopped by him. Jeff explained breathlessly. The driver reached for his cellphone as soon as he heard about Mark. “Better get the helicopter in there,” he said immediately. But Jeff wasn't sure about that because everything got unclear and then went black and quiet.

    Hours later, Jeff opened his eyes to find his father on a chair nearby. “You're a hero, son,” his father said with a smile. “You had the helicopter sent into the canyon after Mark. I can't tell you how happy I was when I saw it overhead. They got him to the hospital. He's going to be fine soon. I'm so proud of you!”

    You may be familiar with those quotes, but seldom can you associate these quotes with those outstanding women behind them, not to mention the great work they did.

    “Despite everything, I believe that people are really good at heart.”

—Anne Frank (1929 — 1945)

    Hiding from the German forces, Anne Frank, a young Jewish girl, was gifted a diary by her father when she was 13. However, her diary was published after her death in Bergen-Belsen concentration camp at the age of 15. The diary served as a unique eye-witness account of life during Holocaust (mass murder of about six million Jews during World War II) and it became one of the world's most read books.

    “Not all of us can do great things• But we can do small things with great love.”

—Mother Teresa (1910 — 1997)

    Mother Teresa, the Nobel Peace Prize winner (1979), aimed at looking after those children who had nobody to look after them through her own order “the Missionaries of Charity”. She worked tirelessly towards her goal until her ill-health forced her to step down in March 1997, after which she took her last breath in September 1997.

    “If you set out to be liked, you would be prepared to compromise on anything at any time, and you would achieve nothing.”

—Margaret Thatcher (1925 — 2013)

    Margaret Thatcher was loved and hated equally for some of her policies but she never compromise (妥协). She was known as “the Iron Lady” for her leadership style. From being a grocer's daughter to graduating from Oxford University to becoming a banister, she went on to become Britain's first and to date, only female Prime Minister elected in 1979 and the country's fifth longest serving leader.

    “I knew someone had to take the first step and I made up my mind not to move.”

—Rosa Parks (1913 — 2005)

    Also known as “the first lady of civil rights”, Rosa Parks was a pioneer of civil rights in a racially segregated Alabama in 1950s. In 1955, she refused to give away her seat to a white passenger in a bus, disobeying the bus driver's orders. This act of hers sparked the Montgomery Bus Boycott that crippled the state capital's public transport system.

    Papa was a ranger. He worked with horses. He always wore clean clothes with a hat even when he worked. His hat was always the same kind of a cowboy hat—large black hat of heavy wool. He wore his hat full and high. I think he wanted to look taller than he really was.

    Mama was proud of the way he looked when he wore his hat and his best clothes. But in some way she got the idea that papa would lose his hair if he kept wearing a heavy wool cowboy hat in the hot weather. She began to talk about his hat.

    "Papa, "she said one day, "why don't you get a nice cool straw hat? That heavy wool cowboy hat may cause losing hair!" Papa laughed at her and explained that the horses wouldn't recognize him if he changed the hat. But she didn't believe him.

    Mama talked and talked about the hat all summer long. At last papa answered, a little angry, "It would not the cowboy hat but a wife's talking about the hat that makes me lose my hair."

    Mama had a very serious look on her face. She went straight out and later came home with a straw hat. It was a bad year for ranger and we didn't have much money. She thought that if she spent the money for a straw hat, papa would wear it. When papa saw the hat, his face got red. Without a word, he pulled the straw hat down over his head until it hid his eyes and went on to train the horses.

    He was a good ranger and gentle to his horses. But as papa got close to the horses this time, they jumped high into the air, raising their front feet. All of them ran around in the rounded field and then raced toward the barn. Papa began to shout "Woo boys. Steady boys, steady." But there was nothing equal to.

    Papa walked back straight to the stove in the kitchen, pushed the straw hat deep down into the fire then turned to mama, in a way that even frightened me. "Now listen to me, mama. Understand this I will never wear a straw hat or any other kind of hat my horses do not like. "Then he put on his wool cowboy hat and walked out of the house.

    I never heard mama talk any more about hats. Perhaps, that is why when papa died many years later, there was a round spot on the top of his head where there was no hair.

    Forest Schools originated in Sweden in the 1950s and spread to other countries, particularly Denmark where they have become an important part of the Danish early years program.

    In a typical Danish Forest School, young children from 3 years are taken into the forest for 4 hours each day of the week. They take no toys with them, but instead use only what the forest provides (and their imaginations) to develop their games. There is a primitive hut in the forest, which is used in extreme weather. Activities are child-led and fun, such as finding small animals or stomping in puddles. Because of high adult to child ratios, children can safely try out activities which are often considered too dangerous, such as climbing trees or lighting fires, and by dressing the children in good protective clothing, they are able to play freely. By setting children small manageable tasks at which they are unlikely to fail, and giving genuine praise, children's independence and confidence grow.

    A Swedish scientific study found that children in the Forest School are more balanced and socially capable, have fewer sick days, are more able to concentrate and have better co-ordination than the city nursery children. The primary reason appeared to be the greater opportunities to play in nature, so that children play for longer at a time, tending not to disturb each other as much as children in the city nursery. The study observed that where children were interrupted, they became irritable, their stress level rose, and their ability to concentrate fell.

    The study also showed that the Forest School children had 25 % fewer sick days than the city children. One reason for this is that the air is nearly always better outside than indoors. Outside a child is not so exposed to virus and bacteria and not so likely to be infected by other children. Another reason may be that, since stress has been shown to have a negative effect on the immune system, high stress levels may be weakening the city children. The Forest School children, on the other hand, are in a pleasant, natural, fun and less stressful environment.
