The internet can be addicting. People would do a quick search on an interesting topic, read on and find themselves reading more and more topics totally different from the topic which piqued their interest. It’s like playing a video game and most of us can relate to that. Once we start playing the first few stages of the game, we are progressing and finally finish the story of the game. It’s addictive. Now put that in the perspective of learning – reading and studying topics which get deeper and deeper, until it becomes addictive.
