Too much email and text messaging are signs of insanity (via Drudge).  Do you have any of these
four symptoms?

1. Suffering from feelings of withdrawal when a computer cannot be accessed
2. An increased need for better equipment
3. Need for more time to use it
4. Experiencing the negative repercussions of [your] addiction

If you do, then it is time to get a life.  Turn it all off, put it away, and try talking to people for a change.
