I have recently learned that all computer screens on the inside are covered with bacteria, dust, germs, etc. that can be dangerous to your health.
This is caused by a variety of reasons and it can prove to be a health hazard for everyone that uses the computer. Some say that this problem can be as dangerous as cigarette smoking because of the time that most of us are now spending on computers for work and personal reasons.
