Keyboards

Okay, we all suspected the keyboard we use at home or at work is dirty, but we had no idea how filthy it can actually be. By comparison, the average toilet seat has 50 bacteria per square centimeter, while the keyboard you use everyday has around 2,000. Why is this? Because toilets are cleaned on a frequent basis, while keyboards do not often undergo such a treatment. All dirty things we touch everyday wind up on the keyboard, day after day and week after week. Yes, that goes for the mouse in your hand, too.
