Aerial performer Jennifer Bricker was born without legs, but she never let it stop her.

    Wrapped in a loop of red silk hung from the ceiling Jennifer Bricker climbs and twists to the music. Her head hangs down and her strong arms let go as she balances on her back, high above the ground a move that's all the more daring because she has no legs.

    Jennifer was a few months old when she was adopted by Sharon and Gerald Bricker. She had big brown eyes, a bright smile, and huge amounts of energy. When a doctor advised her adoptive parents to carry her around in a kind of bucket, they refused.

    Jennifer soon learned to walk — and run — on her hands and bottom, and grew up fearlessly climbing trees and bouncing on the trampoline（蹦床） with her three older brothers. “My parents didn't treat me differently so I didn't grasp the concept that I was different. I knew I didn't have legs but that wasn't stopping me from doing the things I wanted to do.”

    At the age of three she was fitted with artificial legs, but she never really took to them — she moved more freely without.

    In 1996 the Olympic Games took place in Atlanta. Jennifer loved to watch the women's gymnastics team, and especially adored the 14-year-old Dominique Moceanu who competed for the US. When Moceanu and the women's team won gold, Jennifer decided she was going to be a gymnast, too. She took up power tumbling, which involves performing floor exercises down a runway. But Jennifer did not want any allowances to be made for her disability.

    At the age of 10 she took part in the Junior Olympics and by age 11 she was tumbling champion for the state of Illinois.

    Jennifer now travels the world as an inspirational speaker and acts as an aerial performer.

    As a child, Alain Robert was afraid of heights. When he was 12, he returned home from school. At the front door of his building, he looked for his keys. he didn't have them. It was 3:30 and his parents worked until 6:00 pm. Alain looked at his apartment on the eighth floor. He saw an open window. He closed his eyes and imagined himself climbing the building. When he opened his eyes, he told himself ,"I can do it." Fifteen minutes later, he was in his house and his fear of heights was gone.

    Today, Alain still climbs buildings. In 2003 , he climbed a building in London dressed as Spiderman(蜘蛛人) to advertise the movie. In 2004, he climbed Taipei 101 (one of the tallest buildings in the world). To reach the top of a building, Alain uses only his hands and special shoes. He has no rope or other safety tools.

    Alain climbs as a hobby. He also does it to make money for charity. When he climbs, he wants to send a message to people. If you have a dream—something you really want to do—it can become real. But you must be brave and keep trying. If something bad happens, don't give up. Close your eyes and tell yourself, "I can do it."

    Every day when Glen Oliver orders his morning coffee at the drive-through window of a local cafe, he insists on paying for the order of the person behind him. He also asks the restaurant workers to tell the customer to have a great day, in case they're not already having one.

    Oliver has never made a big deal out of his own generous actions until a letter was published by a news website in November. He found out that he had not just bought someone his breakfast —he had saved a life.

    According to the website, someone had written a letter stating that on July 18th, he was planning on committing suicide. The writer said that while he was at the drive-through window, he was planning on going home, writing a note and ending his life. When he went to pay for his coffee and muffin, however, the cashier told him that the man in the SUV in front of him had picked up the tab and told him to have a great day.

    “I wondered why someone would buy coffee for a stranger for no reason,” said the writer. “Why me? Why today? If I were a religious man, I would take this as a sign. This random act of kindness was directed at me on this day for a purpose.”

    When the writer arrived home, he couldn't hold back his tears and started to think about the simple good deed that had affected him so deeply. “I decided at that moment to change my plans for the day and do something nice for someone. I ended up helping a neighbor take groceries out of her car and into the house.”

    The writer says that in the months following that fateful event, he does at least one kind thing for others every day. “To the nice man in the SUV, thank you from the bottom of my heart. Please know your kind gesture has truly saved a life,” he said. “On July 18, 2017, I had the greatest day.”

    You discover a shampoo that leaves your hair looking beautiful. But gradually, as you use it more, it's magical effects seem to disappear. "It's just your hair getting used to it, "your mom says. And so you put the shampoo away and look for your next wonder product.

    It sort of makes sense -why would something that left you looking nice at first suddenly start losing its effect after some time? Are there some other factors(因素)at play? Can your hair really get used to a certain shampoo?

    Marie Claire spoke to hair experts and it turns out that it's not true. Your hair cannot get so used to a product that it just stops working.

    So what is the deal? Cynthia Alvarez, a famous hair stylist, explained that there are a number of factors leading to your hair puzzle, but basically, it's not the shampoo. "A shampoo does not stop working because your hair get used to it, she said." If your shampoo stops giving you the results you want, the condition and needs of your hair have most likely changed, or the season may have changed -it's more humid(in $), the sun is stronger, or the air is drier. Your state of health may also be different from a recent illness.

    In other words, you need to give up blaming the shampoo. So what can you do to make your hair look beautiful for a little longer? Alvarez suggests changing your ways of hair care when factors, such as the weather, change. Experts also suggest keeping an eye on the amount of shampoo and conditioner(H%i )you're using because over conditioning can be bad for your hair.

    People have grown taller over the last century, with South Korean women shooting up by more than 20cm on average, and Iranian men gaining 16.5cm. A global study looked at the average height of 18-year-olds in 200 countries 1914 and 2014. The results show that while Swedes were the tallest people in the world in 1914, Dutch men have risen from l2th place to claim top spot with an average height of 182.5cm. Larvian women, meanwhile, rose from 28th place in 1914 to become the tallest in the world a century later, with an average height of 169.8cm. James Bentham, a co-author of the research says the global trend is likely but once you average over whole populations, genetics plays a less key role," he added.

    But while height has increased around the world, the trend in many countries of north and sub-Saharan Africa causes concern, says Elio Riboli of Imperial College. While height increased in Uganda and Niger during the early 20th century, the trend has reversed in recent years, with height decreasing among 18-year-olds.

    "One reason for these decreases in height is the economic situation in the 1980s," said Professor Alexander. The nutritional and health problems that followed the policy of structural adjustment, he says, led to many children and teenagers failing to reach their full potential in terms of height.

    Bentham believes the global trend of increasing height has important implications. "How tall we are now is strongly influenced by the environment we grew up in," he said. "If we give children the best possible start in life now, they will be healthier and more productive for decades to come."

Is forgiveness against our human nature? To answer our question, we need to ask a further question: What is the essence of our humanity? For the sake of simplicity, people consider two distinctly different views of humanity. The first view involves dominance and power. In an early paper on the psychology of forgiveness, Droll （1984） made the interesting claim that humans' essential nature is more aggressive than forgiving allows. Those who forgive are against their basic nature, much to their harm. In his opinion, forgivers are compromising their well-being as they offer mercy to others, who might then take advantage of them. 

The second view involves the theme of cooperation, mutual respect, and even love as the basis of who we are as humans. Researchers find that to fully grow as human beings, we need both to receive love from and offer love to others. Without love, our connections with a wide range of individuals in our lives can fall apart. Even common sense strongly suggests that the will to power over others does not make for harmonious interactions. For example, how well has slavery （奴隶制） worked as a mode of social harmony?

From this second viewpoint of who we are as humans, forgiveness plays a key role in the biological and psychological integrity of both individuals and communities because one of the outcomes of forgiveness, shown through scientific studies, is the decreasing of hatred and the restoration of harmony. Forgiveness can break the cycle of anger. At least to the extent the people from whom you are estranged （不和的） 'accept your love and forgiveness and are prepared to make the required adjustments. Forgiveness can heal relationships and reconnect people. 

As an important note, when we take a Classical philosophical perspective, that of Aristotle, we see the distinction between potentiality and actuality. We are not necessarily born with the capacity to forgive, but instead with the potential to learn about it and to grow in our ability to forgive. The actuality of forgiving, its actual appropriation in conflict situations, develops with practice.
