I can39。t remember right now.”Have you ever heard your grandparents ask questions like this sometimes? Usually, we think that older people39。s memory bees bad because their brains get weak. But now a team of scientists at the University of Tubingen in Germany has a new idea. The human brain works slower in old age,” says Michael Ramscar, the lead scientist. But only because they have stored more information overtime.” The findings are based on a series of puter simulations(模擬 ) of learning and memory. Scientists let the puters read a certain amount of words and learn new things each day. When the puter reads only so much, its performance on cognitive(認(rèn)知 )tests is similar of a young adult. But if the puter learns the experiences we might encounter over a lifetime, its performance is similar to that of an older adult. Often it is slower, but not because its processing capacity has declined.

It is reported that only a small number of pupils cycle to school (under 2%), although one in three children would actually like to. Experts say that to stay healthy, children need at least one hour of proper exercise every day. But only six out of ten boys and four out of ten girls get that. One of the reasons is that parents have developed a habit of driving their children to school when they could just walk or
