Don't Eat at Your Desk
In addition to potentially dripping mustard on your suit, studies have found that turning your cubicle into a makeshift restaurant can also increase the germ factor on your desk. It's good policy not to eat off a surface with more than 1,000 bacteria per square inch, but most desks harbor about 21,000 bacteria per square inch [source: ABC News; Weigel]. Let's put that into perspective. Most toilet seats have less than 1,000 bacteria per square inch. And a kitchen sponge can have more than 50 million microorganisms living within it -- by far one of the filthiest things in your house [source: Maloof]. Unless you're fastidious about sanitizing your workspace -- and who among us is? -- you might want to reconsider desk dining.
