It forces you into addiction. It alters the feel-good hormones in you brain. And every addict will tell you the same thing, their poison will give them relaxation and clears their mind. Same as alcoholic, watching frequent porn, frequent coffee drinker and drug addict. The difference is how strong/mild and how harmful it is to the human body. The more they do it, the more they built up tolerance, hence doint more of the same activity.
