Are children becoming addicted to the Internet?

    Children are becoming addicted to the Internet and for many it is one drug that can't be beaten. Not all children, but an alarming number of them are being swept up in this age of digital information.

    Websites like Myspace, Youtube, and Facebook, are becoming so popular that many kids can't help but to be addicted to them just in order to fit. Why not become part of a society where you judged by how many friends on a friend list ? What has become of the world , when instead of calling your best friend on the phone you send them a message electronically and wait around for hours to see if they get on and read it ?Often on the web there just aren't enough adults setting kids straight and too many teenagers causing trouble .

    However, it is biased to claim all kids are addicted, or even that all kids who are addicted to the web are negatively affected by it. While the web can be a large waste pool of negative influence, it is also a wealth of positive knowledge, friendly social networking, and even gateways to future employment. Perhaps it isn't so important whether or not a child is addicted to the web and more important that parents know exactly what the kids are doing there.

    Many computers have optional parent controls that allow parents to block the children from entering certain types of sites, or even individual ones. Such programs are unfortunately not used enough by today's parents, who in many cases are caught up on computers themselves. All one needs to do is google search parental controls and you will be provided with any number of companies that can help with programs for tracing child activity and, if necessary, limit time spent on the Internet .

    Why do some people live to be older than others? You know the standard explanations: keeping a moderate diet, engaging in regular exercise, etc. But what effect does your personality have on your longevity(长寿)? Do some kinds of personalities lead to longer lives? A new study in the Journal of the American Geriatrics Society looked at this question by examining the personality characteristics of 246 children of people who had lived to be at least 100.

    The study shows that those living the longest are more outgoing, more active and less neurotic (神经质的) than other people. Long-living women are also more likely to be sympathetic and cooperative than women with a normal life span. These findings are in agreement with what you would expect from the evolutionary theory: those who like to make friends and help others can gather enough resources to make it through tough times.

    Interestingly, however, other characteristics that you might consider advantageous had no impact on whether study participants were likely to live longer. Those who were more self-disciplined, for instance, were no more likely to live to be very old. Also, being open to new ideas had no relationship to long life, which might explain all those bad-tempered old people who are fixed in their ways.

    Whether you can successfully change your personality as an adult is the subject of a longstanding psychological debate. But the new paper suggests that if you want long life, you should strive to be as outgoing as possible.

    Unfortunately, another recent study shows that your mother's personality may also help determine your longevity. That study looked at nearly 28,000 Norwegian mothers and found that those moms who were more anxious, depressed and angry were more likely to feed their kids unhealthy diets. Patterns of childhood eating can be hard to break when we're adults, which may mean that kids of depressed moms end up dying younger.

    Personality isn't destiny, and everyone knows that individuals can learn to change. But both studies show that long life isn't just a matter of your physical health but of your mental health.

    One evening in February 2007, a student named Paula Ceely brought her car to a stop on a remote road in Wales. She got out to open a metal gate that blocked her path. That's when she heard the whistle sounded by the driver of a train. Her Renault Clio was parked across a railway line. Seconds later, she watched the train drag her car almost a kilometre down the railway tracks.

    Ceely's near miss made the news because she blamed it on her GPS device. She had never driver the route before. It was dark and raining heavily. Ceely was relying on her GPS, but it made no mention of the crossing. "I put my complete trust in the device and it led me right into the path of a speeding train," she told the BBC.

    Who is to blame here? Rick Stevenson, who tells Ceely's story in his book When Machines Fail Us, points the finger at the limitations of technology. We put our faith in digital devices, he says, but our digital helpers are too often not up to the job. They are filled with small problems. And it's not just GPS devices: Stevenson takes us on a tour of digital disasters involving everything from mobile phones to wireless keyboards.

    The problem with his argument in the book is that it's not clear why he only focuses on digital technology, while there may be a number of other possible causes. A map-maker might have left the crossing off a paper map. Maybe we should blame Ceely for not paying attention. Perhaps the railway authorities are at fault for poor signaling system. Or maybe someone has studied the relative dangers and worked out that there really is something specific wrong with the GPS equipment. But Stevenson doesn't say.

    It's a problem that runs through the book. In a section on cars, Stevenson gives an account of the advanced techniques that criminals use to defeat computer-based locking systems for cars. He offers two independent sets of figures on car theft; both show a small rise in some parts of the country. He says that once again not all new locks have proved reliable, Perhaps, but maybe it's also due to the shortage of policemen on the streets. Or changing social circumstances. Or some combination of these factors.

    The game between humans and their smart devices is amusing and complex. It is shaped by economics and psychology and the cultures we live in. Somewhere in the mix of those forces there may be a way for a wiser use of technology.

    If there is such a way, it should involve more than just an awareness of the shortcomings of our machines. After all, we have lived with them for thousands of years. They have probably been fooling us for just a. s long.

    Age has never been a problem for 16­year­old Thessalonika Arzu­Embry. After all, she's already got her master's degree.

    The North Chicago­area teen started homeschooling at the age of 4. She began having an influence on others soon after. When she was 6 years old, she was an inspirational speaker at an organization called Tabitha House Community Service, a shelter for people who were forced to leave their homes due to the situations such as earthquake, flood and other natural disasters.

    At the age of 11, she graduated from high school and then earned her bachelor's degree in psychology in 2013. She completed those classes online as she was traveling for church events and leadership meetings.

    She doesn't stop there, though. The teen plans to focus on aviation psychology(航空心理学) for her further study, a decision inspired by her father who is a pilot. She grew up around airplanes and took fights all the time. Her goal is to use it to determine whether pilots are dealing with problems that could have deadly results once the plane takes off­a topic that has been in the news lately. For her, it's a mix of two of her interests.

    In her free time, Thessalonika enjoys playing tennis, swimming and being active in her youth group at church. She also has three self­published books, which are on her site. Jump the Education Barrier is written to help students finish college, and in the future aims to help business owners with trends. Her third book The Genius Race, has a wider appeal. It is designed to help people to be geniuses in various areas of life.

    Triple Olympic and world sprint(短跑) champion Usain Bolt of Jamaica said on Monday he expects years of fast feats to ease doping doubts in athletics and has no plans to play American football.

    Appearing on ESPN programs and in light-hearted races outside the television sport network's studios, Bolt said he feels he must prove himself to a skeptical sports world in the wake of past doping scandals(诽谤).

    "I have to prove myself to the world that you can run fast without it," Bolt said.

    Bolt cited the speeds he and countryman Asafa Powell and American Tyson Gay have achieved without positive doping tests.

    "We just (have to) continue to run fast," Bolt said. "In a couple of years everyone will continue to watch again and have less doubts."

    Bolt won gold in the 100m, 200 and 4x100 relay in world record times at last year's Beijing Olympics and last month in Berlin set world records of 9.58 seconds in the 100 and 19.19 in the 200 and helped a relay title in a World Championships treble.

    "I want to be a legend in the sport. For me it's all a focus on winning championships after championships," Bolt said.

    "I don't consider myself a legend. When I defend my titles I will consider myself a legend."

    Bolt's defending of World and Olympic gold should be the feature attraction of the 2011 IAAF World Championships in Daegu, South Korea, and the 2012 London Olympics.
