Modern means of communication are changing every time. They influence our life immensely. If many centuries ago people did not know about them, nowadays we cannot imagine our life without them. Among modern means of communication, my most favourite are a cell phone and the Internet. I talk to my family and friends on phone every day and it is very comfortable. As for the Internet, virtual communication makes it easier to make friends. But, of course, means of communication are very harmful for our health. People are so addicted to them that they don't pay attention to the risk. I think that modern means of communication are harmful but, if to use them carefully, you can possibly avoid it.
