Typing-using computer

  I like to use computer. I often use computer to watch movie and do homework like this. I often use computer in the midnight, so I think this is bad for my health. My mother says that you use this in the light room, but I don’t like too light, so I usually use this in the dark room. I understand what mother says, but I can’t stop to do this way. Using computer is the important way to work in this world in my future. However, I think that it is bad my health to use computer too long.
