I am a big fan of the internet. It's really great. You can chat with your friends and search for usefull information.
Also you can watch your favourite films.
It is also good for listening nice music.
Plus, you can find lots of information for studying.
The only problem with the internet is that it takes a lot of time and you don't do anything in real life.
In brief, internet is interesting and usefull but it makes your health worse.
