жуть и жесть

Television became an essential part of our life/ It is important to mass media, knowledge source, and leisure pastime. Modern children watch TV and play video games from childhood. And sometimes do it too much.
On one hand, if the children and teenagers watch TV, they can discover and learn many new, interesting and useful things, like scientific facts, historical and cultural realities etc. According to some experts, with the help of video and computer games, it is possible to develop logical thinking, erudition, expand the circle of interest, improve memory. For example, my friend plays in quests, and he has such useful qualities that fast reaction, concentration, ability to find a way out of difficult situation. Thus spending free time playing video games and watching television can be considered a good use of leisure time.
On the other hand, watching TV and playing computer games too excessive may bring damage to physical, psychological and mental health, like headache, a decrease of acuity, irritability, insomnia and so on. Also, computer games replace reality, because American association of Psychiatrists includes gambling addiction in the list of mental disorders. I can illustrate this in one example in my experience/ In my class in primary school was one boy, who too many of his free time spends by playing computer games. He was very aggressive, emotionally labile, nervous and very difficult to communicate. so, can be concluded, that it is bad to spend much time playing video games and watching TV. And instead of it, it is necessary to find more productive activities, which can bring some benefits. It may be different art exercises, kinds of sports, learning something intellectual development etc.
To summarize can be said that playing computer games and watching TV have positive and negative sides. In my opinion, everything is good in moderation. And one should know when to stop. Although the border between "much" and "too much" often is difficult to determine.
