Teen obesity means the problem of very overweight teenagers. Obesiry for a teenager happens when his or her BMI(身体质量指数)is more than 95 percent greater as compared to other teenagers of the same gender(性别)and age.
The term "obese" is commonly used by doctors wh. en a person's weight can badly affect their health. Obesity can be caused by genetics and habits such as eating unhealthy food and not getting enough exercise.
Teen obesity can lead to several health problems. Obese teens are at greater risk of deve-loping health complication(并发症)，such as type-2 diabetes（糖尿病），high blood pressure and high cholesterol(胆固醇). If they remain obese into adulthood, these teens can also raise their chances of developing heart disease.
In addition, there can be many psychological effects of teen obesity. Some experts believe there is a strong link between obesity and self-identity(自我认向)．If teens are treated poorly by other teens, they may have the feeling of low self-esteem(自尊), loneliness and depression Health experts recommend several ways to control teen obesity. The most common sugges-tions are eating balanced meals with enough fruit and vegetables in addition to getting 60 minutes of exercise daily. Eating a good breakfast can also help according to some doctors.
Doctors suggest that teens avoid trying to go on a diet and instead learn to how to make lifestyle changes.Some experts also recommend making the entire family take part in healthier habits to make the obese teen feel less alone. Parents can also avoid talking about health weight in terms of "fat' and "thin" and instead say that each person's ideal size is different

Speaking two languages can actually help offset(抵消) some effects of aging on the brain, a new study has found,
Researchers tested how long it took participants to switch from one cognitive(认知的) task to another, something that-s known to take longer for older adults, said lead researcher, Brian Gold, a neuroscientist at the University of Kentucky.
Gold’s team compared task-switching speeds for younger and older adults, knowing they would find slower speeds in the older population because of previous studies. However, they found that older adults who spoke two languages were able to switch mental activities faster than those didn’t . The study only looked at life long bilinguals(会说两种语言的人) defined in study as people speaking a second language daily since they were at least 10 years old.
Gold and his team asked 30 people, either bilingual or monolingual(只僮一种语言 人) , to have a series of tests. They found that bilingual people were not only able to switch tasks faster they had different brain activity than their monolingual peers.
Kristina called bilingualism "a beautiful natural experiment”, because people grow up speaking two languages,and studies have shown that they get certain cognitive benefits from switching between languages and determining which to respond with based on what's going on around them.
Gold said he grew up in Montreal, where he spoke French at school and English at home, prompting relatives to question whether his French language immersion would somehow hinder his ability to learn English.
"Until very recently, learning a second language in childhood was thought of as dangerous," he said. "Actually, it's beneficial. "

Whenever you buy something, it is possible that someone has already worn, eaten, or tested
it to make sure it is safe and do what is supposed to do. But what if you wanted a special suit to keep a shark from hurting you? Who wants to test a product like it?
"I do! " says Jeremiah Sullwan, a scientist in California "You have to believe in what you sell, right?"
Sullivan. owns SharkArmor Tech, a company that makes a $ 49400 sharksuit that even a great white shark can’ t bite through. Before Sullivan could sell his sharksuits, he needed to make sure his design would work. Sullivan put on the sharksuit and jumped into a shark feeding ground. "I need to know exactly what a human body could expect to go through," he says. Sharks moved all around him and then attacked his arm. Sullivan felt the bite but no teeth. He was uncomfortable at times, but not painful. The suit works! "
"I’ve now been bitten thousands of times but. never badly," says Sullivan, who now works with shows like Wild Kingdom, and programs for the Discovery Channel’s Shark Week.
So,are you all set to buy a sharksuit? Before you do, you should know that the suit weighs 20 pounds and makes swimming almost impossible--not so practical for a day on the beach. And in fact, Sullivan wants only professionals, such as filmmakers, scientists and drivers, to have sharksuits. Why? Because even if someone is wearing a sharksuit, they could get seriously hurt if they treat diving with a 4,OOO-pound shark as a game.
During sharksuit testing, sharks have thrown Sullivan to a bottom o/ reefs(礁) and tried to take him off into the deepest part of the ocean. "However," Sullivan says," you don't need to be afraid of sharks. It’s actually pretty hard to get a shark to bite you, "
