Can you believe your eyes? A recent experiment suggests that the answer to that question may depend on your age.

Martin Doherty, a psychologist at the University of Stirling in Scotland, led the team of scientists. In this experiment, Doherty and his team tested the perception(观察力) of some people, using pictures of some orange circles. The researchers showed the same pictures to two groups of people. The first group included 151 children aged 4 to 10, and the second group included 24 adults aged 18 to 25.

The first group of pictures showed two circles alone on a white background. One of the circles was larger than the other, and these people were asked to identify the larger one. Four-year-olds identified the correct circle 79 percent of the time. Adults identified the correct circle 95 percent of the time.

Next, both groups were shown a picture where the orange circles, again of different sizes, were surrounded by gray circles. Here’s where the trick lies in. In some of the pictures, the smaller orange circle was surrounded by even smaller gray circles — making the orange circle appear larger than the other orange circle, which was the real larger one. And the larger orange circle was surrounded by even bigger gray circles — so it appeared to be smaller than the real smaller orange circle.

When young children aged 4 to 6 looked at these tricky pictures, they weren’t fooled — they were still able to find the bigger circle with roughly the same accuracy as before. Older children and adults, on the other hand, did not do as well. Older children often identified the smaller circle as the larger one, and adults got it wrong most of the time.

As children get older, Doherty said, their brains may develop the ability to identify visual context. In other words, they will begin to process the whole picture at once: the tricky gray circles, as well as the orange circle in the middle. As a result, they’re more likely to fall for this kind of visual trick.

Over three million people will do their Christmas shopping entirely online this year without once visiting an actual shop, a poll (民意调查) has found. Overcrowding and long queues in shops are forcing people away from the high street as the hassle (烦扰) of Christmas shopping becomes too much.

The number of people turning their backs on the high street is almost one million higher than it was last year, according to the poll by YouGov. Last Christmas 2.4 million shoppers did not do any of their shopping in actual shops. The figure this year is predicted to be around 3.4 million, equal to around 7 percent of the adult population.

Over a third of people said that the main turn-off about shopping on the high street is 0ver-crow-ding. Meanwhile almost a quarter said that long queues at the cheek-out are the worst thing about it.

Of the 2.065 people pored, even those who are stir taking to the shops plan to spend less time in them this Christmas. Around 31 percent of shoppers who plan to spend at least some time on the high street will spend less than half of their shopping time in actual shops, using the rest of the time to shop remotely via the internet. This compares to 28 percent of people last year. Meanwhile the proportion of people spending over half of their shopping time in high street shops has dropped from 41 percent last year to 39 percent this year. Just 2 percent of people said that they are looking forward to dealing wi.th store staff this festival season.

Guy Boxall, senior product marketing manager at Casio Business Solutions Division, which commissioned the research from YouGov, said that despite the fall in people visiting the high street,humans are "social creatures" who actually like spending time together.

"Although the high street is facing a big challenge Christmas, retailers (零售商) should see this research as a challenge to improve the in-store shopping experience, rather than the nail in the coffin. We are social creatures, and the desire to spend time with each other, particularly at Christmas, is never going to go away," said Mr. Boxall.

Many facts suggest that children are overweight and the situation is getting worse, according to the doctors. I feel there are a number of reasons for this.

Some people blame the fact that we are surrounded （包围） by shops selling unhealthy, fatty foods, such as fried chicken and ice cream, at low prices. This has turned out a whole generation of grown-ups who seldom cook a meal for themselves. If there were fewer of these restaurants, then probably children would buy less take-away food.

There is another argument that blames parents for allowing their children to become overweight. I agree with this, because good eating habits begin early in life, long before children start to visit fast food shops. If children are given fried chicken and chocolate rather than healthy food, or are always allowed to choose what they eat, they will go for sweet and salty foods every time, and this will carry on throughout their lives.

There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers and play computer games. Not only is this an unhealthy pastime（消遣）, it also gives them time to eat more unhealthy food．What they need is to go outside and play active games or sports.

The above are the main reasons for this problem, and therefore we have to encourage young people to be more active, as well as steering them away from fast food shops and bad eating habits.

The Healthy habits survey(调查) shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.

1. How many times did you brush your teeth yesterday? ● Findings: A full 33% of seniors brush their teeth only once a day. ● Step: Remove the 300 types of bacteria in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day. 2. How many times did you wash your hands or bathe yesterday? ● Findings: Seniors, on average, bathe fewer than 3 days a week .And nearly 30% wash their hands only 4 times a day---half of the number doctors recommend. ● Step: We touch our faces around 3,000times a day ---often with hot running water and soap for 20 seconds. 3. How often do you think about fighting germs(病菌)? ● Findings: Seniors are not fighting germs as well as they should. ● Step: Be aware of germs. Do you know it is not your toilet but your kitchen sponge (海绵) that can carry more germs than anything else? To kill these germs, keep your sponge in the microwave for 10 seconds.
