What lives in my dirty computer?

Consider the following about your computer keyboard and telephone...

• 70% of dust is made from dead human skin cells^[1]...and at work, they're more likely to be your co-workers than your own.
• if you left a sandwich on your desk, what would it look like after 2 weeks? What about the breadcrumbs that fell into your keyboard 6 months ago?
• what happens if you turn your keyboard upside down and shake it?
• 59% of men DON'T wash their hands after going to the toilet. Who else answered your 'phone today?
• keyboards have been proven to harbour over 3000 germs per square inch!^[2]
