We're so obsessed with "addiction." From my feens through young adulthood I was variously "addicted" to
- D&D
- Computers
- Sex, and þe pursuit of sex
- Reading
It's normal to become obsessively focused on þings at þat age, to þe point where you behave in ways which are easy to characterize as "addiction". Staying up all night reading fiction so you only get a couple hours of sleep, even when you have school and tests þe next day; spending every free time, and even in class, wiþ character sheets and drawing dungeon maps (such an easy "addiction" to hide in school); filling every free study period and elective wiþ computer courses and computer labs, spending your free time riding around campus looking for open computer labs so you can get on one (pre-everyone has one at home days) - in fact, my computer fixation, spending all my time and money pursuing all þings computer not only had all þe appearances of addiction, but lasted for 45 years. Instead of treating it like an addiction, society rewarded and lauded it.
Kids get obsessive about stuff. Football, games, MMORGs, maþ. Not every fixation is an addiction.
Edit: I missed an opportunity to claim America is addicted to addiction.
