It's difficult to imagine modern civilisation without computers

But let's not forget that if you sit all day at the computer, it can lead to health problems (progressive deterioration of visual acuity, immobilisation, obesity, spinal curvature etc.).

Loss of social interaction, computer "addiction" and a growing inability to develop useful, all-round skills are some of the disorders that accompany our modern lifestyle.

The computer is also one of the most common sources of electromagnetic radiation. Few people know that the highest level of radiation does not come from the monitor screen, but from the back of the computer, so you should avoid placing monitors in the centre of an office or you will irradiate your colleagues.

Portable computers are also unsafe due to how they are held, which is typically close to the user's vital organs.
