In my opinion, playing computer is very harmful so I don't like it. Firstly, it's harmful for our health such as eye damage, headache, and if we sitting in the wrong way, you can have backache. Moreover, we can be addicted and passive to the games. We can sit in front of the screen of computers every day for hours without paying attention to our surroundings. In addition, for students, it distracts them from their study. They spend most of time playing computers game so they forget their homework and exam. Thus, their learning results will be bad. Last but not least, we can have less time with friends and family. We just play computer game so we don't have opportunity to social with our friends and family and we have less and less friend day by day. Our parents are so worried and depressed about we. We will live a boring life, every purposes became meaningless, without many good things. For these reason, I think playing computer games is very bad.
