Computer paradise/hell

The back of the kid busy with doing something with computer - this is the usual picture parents see when they come home. Computer is the paradise for children and the hell for adults.
The kid's problem of 21st century is computer. Children forgot about their classmates, real communication, active games, running, swimming, etc. Everything was substituted by computer. Since childhood there is nothing better for children than computer play or just investigating it clicking different buttons.
Make the experiment and put your little child next to computer. Any child that can walk already will get closer to it and will start to do interesting things. Without studying the computer the child will change the wallpaper of your computer, will hide one of the most important folders, etc. And if you give the game to a child be sure, it will be interested in it until the child wins.
I suppose this is the human evolution. We live in the century of computer technologies and net, so maybe our organism starts to adapt to the modern world and maybe nature created some kinds of genes that will be responsible for computer adaptation.
But at the same time computer brings a number of problems connected with sedentary way of life and obesity as the result, bad eyesight, etc. Maybe our physical health will suffer in favour of intellectual health. After all almost all children are born weaker than they were before.
