Yuck! Most cyberworkers spend all day typing away at their keyboards unaware that filthy bacteria lurks between each key.

Which - A UK consumer magazine asked microbiologists to examine the keyboard in a London office, a toilet seat and a door handle for bugs found in unhealthy places.  This study found that some keyboards were potential health hazards with one keybaord containing 150 times the pass limit for bacteria and was 5 times dirtier than the toilet seat.

I am cleaning my keyboard right now, I would suggest you do the same.  Its really easy just turn it upside down!
