I think currently computers are very important part of our lives but also they have their own advantages and disadvantages. The pluses: we can find as much information as we want to; we can communicate with someone who is far from you; you can develop your skills in different spheres. The minuses: our health is not always ready for computer, sometimes you can loose your vision or have backaches; you can become dependent on computer; sometimes you can find some bad photos or videos you shouldn’t see, so it can hit your psyche.
