I am a big fan of social networks.it's really interesting to chat with people over the world.You can search all what you want in the web.There is a good search-Google.You can also watch different movies,play games with your friends,listen to music.It's also good for students,who need to find the information from web.The only problem is that it's not healty for you.Your eyes become tired.So you need to take a rest when you search something.In brief Internet is very helpful.
