    Ever walked to the shops only to find, once there, you've completely forgotten what you went for? Or struggled to remember the name of an old friend? For years we've accepted that a forgetful brain is as much a part of ageing as wrinkles and grey hair. But now a new book suggests that we've got it all wrong.

    According to The Secret Life of the Grown-up Brain, by science writer Barbara Strauch, when it comes to the important things, our brains actually get better with age. In fact, she argues that some studies have found that our brain hits its peak between our 40s and 60s— much later than previously thought.

    Furthermore, rather than losing many brain cells as we age, we retain （保留）them, and even produce new ones well into middle age. For years it's been assumed that brain, much like the body, declines with age. But the longest, largest study into what happens to people as they age suggests otherwise.

    This continuing research has followed 6,000 people since 1956, testing them every seven years. It has found that on average, participants performed better on cognitive （认知的）tests in their 40s and 50s than they had done in their 20s. Specifically, older people did better on tests of vocabulary, verbal memory (how many words you can remember) and problem solving.

    Where they performed less well was number ability and perceptual speed－how fast you can push a button when ordered. However, with more complex tasks such as problem-solving and language, we are at our best at middle age and beyond. In short, researchers are now coming up with scientific proof that we do get wiser with age.

    Neuroscientists are also finding that we are happier with ageing. A recent US study found older people were much better at controlling and balancing their emotions. It is thought that when we're younger we need to focus more on the negative aspects of life in order to learn about the possible dangers in the world, but as we get older we've learned our lessons and are sub-consciously aware that we have less time left in life: therefore, it becomes more important for us to be happy.

    Developed by researchers and designers specializing in typography(印刷术)and behavioral science, Sans Forgetica is a new font(字体)designed to help readers better remember the information they read by forcing them to spend a bit more time on each word.

    The design of Sans Forgetica is based on a font called Albion, but with substantial  modifications(修改)to reduce familiarity and attain its goal of engaging the brain more and helping the reader retain(保留) more information. It was developed by scientists at RMIT University in Melbourne, Australia, who believe it could help students studying for exams.

    “We believe this is the first time that specific principles of design theory have been combined with specific principles of psychology theory in order to create a font, ”Behavioral economist Jo Peryman told DW.

    If fonts are too familiar, readers often glance over them without their brain creating may  memories of what was read. At the same time, if a font is too outlandish, the brain has to struggle too much to decipher(破译)it while neglecting the retention of information. According to its developers, “Sans Forgetica lies at a sweet spot where just enough obstacle has been added to create that memory retention.” Its modifications force readers to spend more time, but not too much time, reading each word, allowing the brain to engage in deeper cognitive processing.

    So does Sans Forgetica actually work? Does it help readers better remember the information they read? So far, studies have shown that it can make a difference, although not a significant one.

    One experiment had 96 participants recall word pairs presented in three different fonts. They remembered 69 percent of the word pairs written in Sans Forgetica, compared to 61 percent for the other fonts. In a different experiment, 303 students took a mock(模拟)multiple-choice exam, and whenever the text was presented in Sans Forgetica, they remembered 57 percent of the text, compared to only 50 percent of the surrounding text written in Arial font.

    So Sans Forgetica won't give you the memory of an elephant, but if you're the kind of person who believes every little bit helps, it might be worth a try.

    Raised in France by her country physician grandfather, Petaluman Laura Reiehek will be recognized for her work helping the homeless, immigrants and elders and she received the Rev. James E. Coffee Human Rights Awards for 2006.

    Her grandfather devoted his whole life to making life better for others and was killed by Nazi soldiers in 1944. She was there when the soldiers took her grandfather's life: "I hid under a pile of leaves. But, you know, I heard it."

    She straggled to work through her anger and hate, but it was necessary for her own survival and serf-respect. After the war, she married Jesse Reichek, an American soldier in France, and they eventually settled in the Bay Area, where he grew to become an artist. They came to Petaluma from Berkeley when he needed more room to paint. They built their own home and treasured their time together.

    Reichek's years of volunteer work began with caring for an old lady in Sonoma County, which made her sensitive to the fact that many older people were living in bad places. So Reichek created Petaluma's first senior center. Then she noticed homeless people. With Mary Isaac, she co-founded COTS 15 years ago.

    These days, she is busier than ever, helping Latino immigrant families and visiting seniors in nursing homes. "Our goal is to promote and educate people in understanding and tolerance (忍受). We must learn to understand and celebrate our differences", said event chairman Harry Troutt, who serves on the commission.

    Cao Zhawa has been planting trees for most of his life. He lives and works in the heart of Mu Us Sandyland, an area in the southwest part of Inner Mongolia.

    In 1958, when he was just 16 years old, Cao started planting trees. Cao's trees now cover an area of more than 1.3 million square meters. Cao's forest is worth an estimated 10 million yuan and can produce 100,000 kilograms oxygen, enough to sustain a full-grown adult for nearly a year.

    Mu Us Sandyland is one of the places in China most affected by erosion(侵蚀) and desertification. The amount of annual rainfall ranges from 150 to 300 millimeters, while evaporation(蒸发) between 2,000 and 3,000 millimeters. Cao recalls that his growing-up was troubled by sandstorms. This was one of the factors that motivated Cao to join and stay on the tree-planting program.

    Popularly known as the "Green Great Wall", the project, which is set for completion in 2050, would be a 4, 800-kilometer greenbelt of trees and shrubs(灌木) protecting the area from strong winds and preventing soil erosion. Since the start of the Three-North Shelter Forest Program, millions of people have joined in and become a vital part of the plan.

    However, the tree-planters face a host of challenges, with watering the most difficult among them. "When I was young, the level of groundwater was high," said Cao, "But with less rain, the trees are hard to plant and keep alive."

    Planting trees has also become harder for Cao as he ages. However, he doesn't want to leave the forest in the care of his children, and he insists the land belongs to the government. "When I die, I just want to be buried under the trees," Cao said. "Then I will be with them forever."
