You don't think that constant (over) consumption of our modern pop culture isn't addictive? Ever known anyone who had their broadband cut off or whose PS2 broke? Contant exposure to general media, including images of sex, death, power and wealth possesed by others don't affect our reward system?

When men see someone they are sexually attracted to, their pupils dialate, their dopamine goes into overdrive, and their short term memory is affected. Men spend billions on prositutes and titty dancers. Sounds just like a drug to me. And you can bet the reward systems of a sex addict or gambler (or internet user) are different from that of a 'normal' human.

There are more simliarities between living in our materialistic culture and a simple chemical intoxication/addiction than you think.
