CANBERRA (Reuters Life!) - Think twice before eating those dropped crumbs off your computer keyboard -- you might as well be eating off a toilet seat, according to a new study on the amount of germs on keyboards. 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. What do you think the expression "Think twice before eating those dropped crumbs off your computer keyboard" stands for? A) Think several times before eating beside your computer B) Don't drop foods onto the computer keyboard. C) Don't eat foods dropped onto the computer keyboard. D) Be careful when you are eating by the computer.

Since 1984, Philadelphia has been cleaning up its act. One by one, graffiti-covered walls are being changed into outdoor art. So far, more than 1,800 murals have been painted. Philadelphia now has more murals than any other American city. The walls that were once ugly with graffiti are now covered with beautiful pictures of historical heroes and modern art, thanks to the Mural Arts Program (MAP). Its work makes schools and public places attractive, and its citizens very proud. The program began as part of Philadelphia's Anti-Graffiti Network. Jane Golden is the MAP's artistic director. "When people ask me what our program is about," she says, "I answer them with one word: hope." Each year, the MAP offers youth art programs and workshops. Some one-time graffiti writers even help paint MAP murals. The MAP's work, says Golden, is all about developing a sense of community . When a neighborhood requests a mural, the MAP works with the people there to develop a message. Some messages have been "Safe Streets," "Love and Care," and "Peace Walk." The MAP receives up to 50 requests for murals each week. Last year, the workers painted 140 murals. "The making of a mural enters people's collective memory as an extraordinary, pleasant moment in neighborhood history" says Golden, who began as a muralist in Los Angeles. What is the Mural Arts Program in Philadelphia aimed at? A) Helping the young find jobs. B) Protecting the neighborhood. C) Fighting against graffiti. D) Attracting more visitors.
