A study by British "Which? Computing" asked a microbiologist to examine for bugs on 33 keyboards in a typical London office, a toilet seat and a toilet door handle.
Four keyboards were judged potential health hazards and the microbiologist recommended the removal of one keyboard as it had 150 times the pass limit of bacteria -- five times filthier than the swabbed toilet seat.
"Most people don"t give much thought to the grime that builds up on their PC, but if you don"t clean your computer, you might as well eat your lunch off the toilet," said Sarah Kidner, the consumer magazine editor of "Which? Computing" in a statement.
The study found that eating lunch at desks is the main cause of a bug-infested keyboard. Dropped crumbs and food encourages the growth of millions of bacteria.
Poor personal hygiene, such as not washing hands after going to the toilet, may also add to the dirtiness of keyboards.
But despite the health hazard of a dirty keyboard, a survey of 4,000 people by the magazine found one in 10 people ever cleaned their keyboard while another two in 10 never cleaned their mouse.
Almost half -- or 46 per cent -- cleaned their keyboard less than once a month.
To clear out bugs, the magazine recommends users unplug keyboards, turn them upside down and shake them.

“Hongo inherited（继承）the title Monday after the death of the previous record holder, Maud Farris-Luse ,of Coldwater , Mich.,”the record-keeping company said on its website.Farris-Luse was 115 years and 56 days old then.
“Hongo, born on Sept .16,1887, was raised on a farm and counts drinking Japanese rice wine among her favorite things ─ along with black salt, pork ,sashimi（生鱼片）and green tea,”according to Guinness. “She also likes traditional Japanese dancing.”
“The key is not storing up stress,”said her 45-year-old grandson Tsuyoshi Kurauchi. “If you do that, you can eat or drink anything.”
“Hongo mothered seven children, more than 20 grandchildren, and even outlived her eldest daughter, who died two years ago while in her 90s,”according to Kurauchi, who described Hongo as a “warm, caring grandmother”.
She lived in a nursing home in Kagoshima, a city about 615 miles southwest of Tokyo on the island of Kyushu, which has reputation for record-breaking longevity among its residents.
Hongo was born in the nearby town of Isen, home to the late Shigechiyo Izumi, who also held the Guinness record as the world’s oldest person. He died in 1986 at the age of 120.
Recently , another Kyushu resident was regarded as the world’s oldest man. Retired silkworm farmer Yukichi Chuganji graduated into the spot on Jan . 4 with the death of his predecessor, Antonio Todde of Italy. Chuganji turns 113 on Saturday.
There are an estimated 15,000 Japanese over the age of 100, and women make up about 80 percent of the total.

From nail-biting to too much hand-washing, overeating and internet addiction（上瘾）,OCD is widespread in almost every workplace and countless home. “It is a relatively common form of anxiety,” says Dr. Mootee. “The main feature of OCD is the repetition of unwanted obsessive（过度的） thoughts such as worries that doors are left unlocked , gas or electrical appliances are left on.” In order to fight against the an esasy checking door locks and gas or electrical appliances.
Dr. Mootee says that repetitive washing, particularly of the hands, is the most common type of OCD. She has treated many patients who wash their hands up to 30 times a day. The technique Mootee uses to treat people with OCD is called cognitive-behavioral therapy（认知行为疗法）.“It is based on the general idea that people have the ability to change the way they think and behave,” says Mootee.
But when does a habit become a problem? “It’s personal,” says Mootee.“Everyone has something unusual, but if you can’t put up with it, then it’s a problem and you need to do something to change it.”Mootee says many people resist for treatment because they fear they are “crazy”. But as people become more knowledgeable about these problems they will go and get help. The only way to cure is to conquer

Sadeh and his colleagues found an extra hour of sleep can make a big difference. The children who slept longer, although they woke up more frequently during the night, scored higher on tests, Sadeh reported in the March/April issue of journal Child Development.
“When the children slept longer, their sleep quality was somewhat weak, but in spite of this their performance for study improved because the extra sleep was more significant than the reduction in sleep quality. ” Sadeh said. “Some studies suggested that lack of sleep as a child affects development into adulthood and it’s more likely to develop their attention disorder when they grow older. ”
In earlier studies, Sadeh’s team found that fourth graders slept an average of 8. 2 hours and sixth graders slept an average of 7. 7 hours.
“Previous research has shown children in elementary school need at least nine hours of sleep a night on a regular basis, said Carl Hunt, director of the National Center on Sleep Disorders Research in Bethesda, and high-school-age children need somewhat less, he said, adding the results of insufficient sleep could be serious.
“A tired child is an accident waiting to happen,” Hunt said. “And as kids get older, toys get bigger and the risks higher. ”Hunt also said too little sleep could result in learning and memory problems and long-term effects on school performance.
“This is an important extension of what we already know, ” Hunt said of Sadeh’s research, adding sleep is as important as nutrition(营养) and exercise to good health.
“To put it into reality,” Hunt said, “parents should make sure they know when their children actually are going to sleep and their rooms are conducive to sleeping instead of playing. ”

| D．In general, children in elementary school need at least nine hours of sleep a night. |
For the last few years, the genetic advances in the developing field of biotechnology have provides material for all kinds of work, but the developments of modern science in unlocking the secrets of the human genetic code(密码) have opened a world of possibilities for human health, as well as for the popular imagination.
While European and Japanese researchers are making rapid progress in decoding(解码) human DNA, the leading organization for genetic research is in the United States, which began in 1990, is “unlocking the code” of the human body to learn how to defeat fatal diseases. Already, the Human Genome Project has become widely known and praised for finding the genes connected with terrible diseases as yet(迄今), and making progress toward separating the genes that show a sign of breast cancer or AIDS.
Once these genes are found and studied, researchers can develop new ways to attack infections, and genetic diseases. Medical companies are very interested in mapping the human genome, as they expect to develop a lot of new drugs for these illnesses.
