If you are a kid, go outside and breathe the fresh air, play baseball, football, go fish, roller blade, build a model, collect something, kick a can, whatever. Just go outside and enjoy being a kid. Don't let the stupid computer eat your brain.
If you're a single adult, GET A LIFE!
Are you married? Go spend time with your spouse. Remind them that you love them. Go for a walk, ride a bike, get out of the house.
Do you have kids? Don't let them spend hours on the computer playing pointless games. Take them somewhere, spend time with them, let them know the computer isn't more important than they are.
