On the day the tornado(龙卷风) hit, there was no sign fierce weather was on its way— the sky was blue and the sun had been out. The first warning my husband, Jimmy, 67, and I, 65, got came around 9 p.m., from some text on the TV Jimmy was watching. He ran upstairs to find me in our third-floor bedroom, and we changed the channel from the national television to our local Pensacola, Florida, station.

    Soon the tornado was on top of us. It was the loudest thing I have ever heard. The bones of the house shook, and the power went out. And the wind began to roar(咆哮) through the house, most likely through blown-out windows and the door to our garage. Everything was moving. And the back wall of the house came off and flew into the darkness outside. We had three flights of steps to get to the storeroom down there, the relative safety of the first floor.

    I didn't know how or if we would make it down the steps. It felt as if there were no floor underneath me as the wind lifted me off my feet. As we finally reached the last flight of steps, our front door blew out. Suddenly, a three-foot-long tree branch flew over our heads, missing us by inches.

    By the time I reached the storeroom, the tornado had been over us for about a minute. Jimmy pushed me down to the storeroom floor, but he couldn't get inside himself because of the wind. I held Jimmy's arm as the tornado blew the door open. My knees were full of glass, but I felt no pain. If I had let go, Jimmy would have flown right out the back of the house.

    All of a sudden, Jimmy lifted off his feet. I thought he was gone. And then everything stopped. He landed on his feet. In those first quiet moments, I couldn't believe it was over. Our neighbor says the storm lasted four minutes. In that time, four of the twelve town houses in our unit were completely destroyed. Amazingly, none of us were seriously injured.

    Chinese researchers say they have come up with a simple way to find out a person's biological age —how much the body has aged physically – through a urine (尿) test.

    Their findings will help researchers conduct numbers of ageing studies and even predict a person's risk of age-related diseases, according to a paper published in the journal Frontiers in Ageing Neuroscience.

    Another paper by researchers at the Beijing Hospital and the West China Hospital in Chengdu, Sichuan province, said on Tuesday that people aged at different rates due to changes in their genetic make-up and their environment.

    Chronological age – which is based on one's birth date —was not an exact measure of biological age so a more exact method was needed, the team said.

    Ageing is driven by the lifelong gradual accumulation(积累) of a broad variety of molecular (分子) faults in the body's cells. The team said they had identified a matter 8-oxoGsn that indicated increases in oxidative (氧化性) damage in urine as people's bodies aged.

    Cai Jianping, a co-author at the Beijing Hospital, said: “As we age, we suffer increasing oxidative damage and so the levels of oxidative matters increase in our body.” The team tested the levels of 8-oxoGsn in urine samples from 1,228 Chinese people aged two to 90 and concluded the marker helped accurately determine the stage of biological ageing in adults.

    They had previously found that 8-oxoGsn levels also increased with age in the urine of animals such as mice.

    The team has also developed a rapid analysis technique called ultra-high-performance liquid chromatography(层析法), which can process up to 10 urine samples an hour, according to the study.

    There is some unwelcome news for students preparing for exams and officers putting in long hours—you don't need that "refreshment (提神) break" as much as you may think.

    Scientists believed it was not easy for people to continue their work if they felt the need to have a snack or a rest to make them feel better. They argued that the only way to regain willpower is by supplying more energy to our bodies with rest, food or entertainment.

    But psychologists have challenged this theory, saying weak willpower is in your head. They found that a person's mindset (理念) and belief about willpower determine how long and how well they'll be able to work on a tough mental exercise. "If you think of willpower as something that's limited, you're more likely to be tired when you perform a difficult task," said Professor Veronika Job. "But if you think of willpower as something that is not easily depleted, you can go on and on."

    The researchers led by Mr. Job designed an experiment to test the students' beliefs about willpower. After a tiring task those who believed or were led to believe that willpower was a limited resource performed worse on standard concentration tests than those who thought of willpower as something they had more control over.

    Mr. Job said, "Students who may already have trouble studying are being told that their powers of concentration are limited, and they need to take frequent breaks. But a belief in willpower as a non-limited resource makes people stronger in their ability to work through challenges."

    The findings could help people who are battling with temptation (诱惑): people following strict diets and doing exercise regularly to lose weight, people trying to overcome addictions, employees facing a tight deadline. Willpower isn't driven by a biologically based process as much as we used to think.

Most parents are worried the first time they catch their kids out in a lie. According to child and teen psychiatrist Gayani DeSilva, lying can actually be a sign of healthy development in young children. "Kids lie for many reasons, and much of it is normal," DeSilva says. "People are not born with the knowledge of communicating with others and getting their needs met. They'll experiment with different communication styles and techniques until they find the ones that work best for them. Lying is one of those techniques."

As kids get older, they become more aware of how their actions affect others, and many will lie less frequently. In spite of this, parents still need to Lead their kids to form a habit of not lying. According to DeSilva, when children lie, look at them directly and ask what they need. After they tell you, gently remind them that telling you directly will be more effective than lying.

It's also a good idea to model the behavior you want to see in your kids. In other words, don't lie to your children. This will set you and your children on a course of open communication and trust.In some cases, lying is a sign of a deeper issue. A child who is neglected will lie more than a child who has attentive and responsive parents. He's not sure whether he's loved. He may lie to please others. The same goes for a child who has experienced something unpleasant. He may lie to try to hide his shame, avoid admitting his needs, or to control his surroundings to ensure his safety.

By paying attention to the reasons behind a lie, parents can figure out what need to be done. For example, while Jack might lie about completing his homework in order to play video games, he also might be trying to avoid negative feelings connected with school work, and this is just where parents should start, says therapist Gideon Javna.
