Big Brothers Big Sisters is based on the simplicity and power of friendship．It is a program which provides friendship and fun by matching vulnerable young people (ages 7-17) with a volunteer adult who can be both a role model and a supportive friend.

    Volunteer tutors come from all walks of life—married, single, with or without children. Big Brothers and Big Sisters are not replacement parents or social workers. They are tutors: someone to trust, to have fun with, to talk and go to when needed.

    A Big Sister and Little Sister will generally spend between one and four hours together three or four times each month for at least twelve months. They enjoy simple activities such as a picnic at a park, cooking, playing sport or going to a football match. These activities improve the friendship and help the young person develop positive self-respect, confidence and life direction.

    Big Brothers Big Sisters organizations exist throughout the world. It is the largest and most well-known provider of tutor services internationally and has been operating for 25 years.

    Emily and Sarah have been matched since 2008. Emily is a 10-year-old girl who has experienced some difficulties being accepted by her schoolmates at school. “ I was pretty sure there was something wrong with me.”

    Emily's mum came across Big Brothers Big Sisters and thought it would be of benefit to Emily by “providing different feedback (反馈) about herself other than just relying on schoolmates to measure her self-worth.

    Sarah wanted to get involved in a volunteer program. “I googled it and found out how to be a part of it. I thought it would be fun for me to get involved in making time to do something because sometimes it is all work and no play.”

    Big Brothers Big Sisters has been of great benefit and enjoyment to both Emily and Sarah. They love and look forward to their time together and the partnership has certainly helped Emily be more comfortable in being the wonderful, happy and unique girl she is!

People aren't walking any more—if they can figure out a way to avoid it.

    I felt superior about this matter until  the other day I took my car to mail a small parcel. The journey is a matter of 281 steps. But I used the car. And I wasn't in ay hurry, either, I had merely become one more victim of a national sickness: motorosis.

    It is an illness to which I had thought myself immune（免疫的）, for I was bred in the tradition of going to places on my own two legs. At that time, we regarded 25 miles as good day's walk and the ability to cover such a distance in ten hours as sign of strength and skill. It did not occur to us that walking was a hardship. And the effect was lasting. When I was 45 years old I raced –and beat—a teenage football player the 168 steps up the Stature of Liberty.

Such enterprises today are regarded by many middle-aged persons as bad for the heart. But a well-known British physician, Sir Adolphe Abrhams, pointed out recently that hearts and bodies need proper…… is more likely to have illnesses than one who exercises regularly. And wlaking is an ideal form of exercise— the most familiar and natural of all.

    It was Henry Thoreau who showed mankind the richness of going on foot. The man walking can learn the  trees, flower, insects, birds and animals, the significance of seasons, the very feel of himself as a living creature in a living world, He cannot learn in a car.

    The car is a convenient means of transport, but we have made it our way of life. Many people don't dare to approach Nature any more; to them the world they were born to enjoy is all threat. To them security is a steel river thundering on a concrete road. And much of their thinking takes place while waiting for the traffic light to turn green.

    I say that the green of forests is the mind's best light. And none but the man on foot can evaluate what is basic and everlasting.

    People with bigger brains tend to score higher on standardized tests of intelligence, according to new study findings.

    However, the study author Dr. Michael A.McDaniel of the Virginia Commonwealth University in Richmond emphasized that these findings represent a general trend, and people with small heads should not automatically believe they are less intelligent. For instance, Albert Einstein's brain was "not particularly large", McDaniel noted." There's some relationship between brain size and intelligence on the average, but there's plenty of room for exceptions," he said.

    Interest in the relationship between brain size and intelligence grew in the1830s, when German anatomist(解剖学家) Frederich Tiedmann wrote that he believed there was "an unquestionable connection between the size of the brain and the mental energy displayed by the individual man". Since that statement, scientists have conducted numerous studies to determine if Tiedmann's assertion was correct. Most studies have looked into the link between head size and intelligence. More recently, however, researchers have published additional studies on brain size and intelligence, measured using MRI scan(核磁共振成像扫描).

    For his study, McDaniel analyzed more than 20 studies that looked into the relationship between brain size and intelligence in a total of 1,530 people. The studies showed that on the average, people with larger brain volume tended to be more intelligent. The relationship between brain volume and intelligence was stronger in women than men, and in adults than in children. McDaniel notes in the journal Intelligence.

    McDaniel is not sure why the relationship was stronger for adults and women. "Other research has shown that women, on the average, tend to have smaller brains than men, but score just as well—if not higher—in tests of intelligence," he said.

    McDaniel insisted that the relationship between brain size and intelligence is not a "perfect" one. "One can certainly find lots of examples of smaller-sized people who are highly intelligent," he said, "But, on the average, the relationship holds."

    On the very first day, God created the cow and said to him, "As a cow, you must go to the field, working under the sun all day long! And I will give you 40 years to live." The cow objected, "What? You want me to live such a tough life for 40 years? Let me have 20 years, and I'll give the rest back to you." So God agreed.

    On the second day, God created the dog and said, "You'll be man's best friend, guarding his house and eating his leftovers. I'll give you a life span of 30 years." The dog shook his head. "Eating leftovers for 30 years? No way! I'll give half back to you!" So God agreed.

    Then, God created the monkey, saying, "Your job is to entertain people. You've got to do monkey tricks and make them laugh. And you'll live 20 years."" Do monkey tricks to make them laugh? 10 years will do." the monkey said. So God agreed.

    Finally, God created the man. "You will be the man. All you need to do is to sleep, eat, and play, simply enjoying your life. And I'll give you 20 years to live." Thinking for a while, the man replied, "I can be the man, but I want to take all the years that the cow, the dog and the monkey didn't want." So God agreed.

    Since then, man eats, sleeps and plays in the first 2 decades, marries and spends the next 2 decades like a cow, working very hard to support his family. Then when he has children, he lives 15 years like a dog, taking care of the house and eating whatever is given to him. And when he is old, he retires and lives 10 years like a monkey, doing tricks to amuse his grandchildren.

    Essentially, everyone has two ages: a chronological(按时间计算的)age, how old the calendar says you are, and a biological age, basically the age at which your body functions as it compares to average fitness or health levels.

    "Chronological age isn't how old we really are. It's merely a number," said Professor David Sinclair at Harvard University. "It is biological age that determines our health and ultimately our lifespan. We all age biologically at different rates according to our genes, what we eat, how much we exercise, and what environment we live in. Biological age is the number of candles we really should be blowing out. In the future, with advances in our ability to control biological age, we may have even fewer candles on our birthday cake than the previous one."

    To calculate biological age, Professor Levine at  ale University identified nine biomarker(生物标志)that seemed to be the most influential on lifespan by a simple blood test. The numbers of those markers, such as blood sugar and immune(免疫的)measures, can be put into the computer, and the algorithm(算式;算法)does the rest.

    Perhaps what's most important here is that these measures can be changed. Doctors can take this information and help patients make changes to lifestyle, and hopefully take steps to improve their biological conditions. "I think the most exciting thing about this research is that these things aren't set in stone," Levine said. "People can be given the information earlier and take steps to improve their health before it's too late."

    Levine even entered her own numbers into the algorithm. She was surprised by the results. "I always considered myself a very healthy person. I'm physically active; I eat what I consider a fairly healthy diet. But I did not find my results to be as good as I had hoped they would be. It was a wake-up call," she said.

    Levine is working with a group to provide access to the algorithm online so that anyone can calculate their biological age, identify potential risks and take steps to improve their own health in the long run. "No one wants to live an extremely long life with a lot of chronic(慢性的)diseases," Levine said. "By delaying the development of mental and physical functioning problems, people can still be engaged in society in their senior years. That is the ideal we should be pursuing."

    On a freezing cold day, a couple had to move into a small apartment because of their failure in business. The husband worked day and night to support the family but gave no care of his wife. So she thought, "He doesn't love me any more. He just cares about his business ... not me"．

    One day, she was about to take a shower when he stopped her at the door, "Let me take it first, okay?" "Why not me first?" she asked. "I am tired, honey, you take it later, okay?" She was entirely unhappy.

    One day, she found nothing to do and turned on his computer. A few words came into her sight. Reading them, she burst into tears. It was his diary：

    Today, I was quite sad. She asked me why I was always taking the shower first, and I said to her, "I was exhausted." She was unhappy. In her mind, I treated her not as well as usual, but what could I do? I was not as rich as before! We moved to the small apartment, and there was only one shower in the bathroom. It was so cold to take a shower in such a cold winter. But I found that if one person took the shower first, the room could get a little warmer. So every day I rushed to the bathroom first. I was thinking that, when she took the shower, the room would get warmer, even if it was only 1℃.

    Now I cannot give her a comfortable life, take her to good restaurants, or buy expensive dresses for her, but at least, I can give her 1℃ love.
