I think that the television is harmful to a high school student. Television in itself is not a so bad thing, but thinks that it is not good to watch television for a long time to tell the truth.
There are the two reasons. Primarily coming to have poor eyesight. A muscle regulating eyesight in what do not move eyes from a screen of the television very much when I watch television for a long time declines. This is what I can say to not only the high school student but also everybody. Second interfering with the study.
In addition, I cannot concentrate on study when I study while watching television.
Thus, I think that the television is harmful to a high school student.
