Like most I'm addicted to my computer/internet I probably wouldn't be able to go a couple days without it. Parents beware, Internet it's the new crack!
Coffee, Coke (as in the beverage), Computers, Internet, Lockergnome, tobacco and Oxygen. The interesting thing is that the last two directly compete with each other.
