I use a computer for work and games, and hang in hundreds of networks, I spend 1-2 hours at the computer, as it is necessary for excellent vision, in my free time I go in for sports, do homework, communicate with friends, do not take much interest programming. I also want to add that if you sit a lot at the computer, you can ruin your eyesight and worsen brain function, so accculist doctors recommend sitting for no more than 2 hours
