M: Hi, Jenny, why are you still eating while you are using the computer?
W: Why? I don’t make the keypad dirty.
M: Think twice before eating those dropped crumbs off your computer keyboard — you might as well be eating off a toilet seat.
W: That’s horrible; I don’t believe that at all.
M: A study by British Consumer magazine who asked a microbiologist to examine for bugs on 33 keyboards in a typical London office, a toilet seat and a toilet door handle.
W: What’s the result? Is it serious?
M: Yes, four keyboards were judged potential health hazards and the microbiologist recommended the removal of one keyboard as it had five times bacteria than the cleaned toilet seat.
W: Most people don’t give much thought to the dust and dirt that builds up on their PC.
M: But if you don’t clean your computer, you might as well eat your lunch off the toilet.
W: Does it mean that dropped crumbs and food encourages the grows of millions of bacteria?
M: Sure, the study found that eating at computer desks is the main cause of bug-infected keyboard.
W: In that way, poor personal hygiene, such as not washing hands after going to the toilet, may also add to the dirtiness of the keyboards.
M: But as far as I know, a survey of 4,000 people by the magazine found one in ten people never cleaned their keyboards while another two in ten never cleaned their mouse.
W: Oh, I should first clean my hands and learn how to clear out bugs.
