Computers are a useful thing, but this good thing also has disadvantages.
What is useful for computers? With the help of this device, we can find information about every corner of our large planet. The computer is also a good assistant in study or work. At the computer, we can spend our leisure time and just play. Not everything is as good as it seems to us.
Doctors recommend us to sit at the computer for an hour or two hours, no more. This is due to the fact that our vision begins to deteriorate, if the eyes do not give a rest. The computer also causes significant harm to our posture: when you are sitting at the computer, you do not keep your back as needed.
There are also rules that tell Us to sit at the computer correctly

Computers: A blessing or a curse?

There aren’t many people who don’t know how to use computers these days. Look in almost any home, classroom or office and you’ll probably spot a computer.
    It is true that computers can save a lot of space and time. Firstly, computers help save a lot of paper and that’s good for the environment. Secondly, computers save space in your house because they can do the job of encyclopaedias and other books. Lastly computers help us learn and allow us to stay in contact with people via e-mail.
     On the other hand, the use of computers can lead to problems. To begin with, computers can be bad for your eyes, especially as some children may spend too much time playing computer games. Moreover, computers don’t help children communicate with others. Instead, children spend their time indoors sitting in front of a computer screen.
     To sum up, computers have their good points and their bad points.
