ReadWriteWeb sums up the nightmare for many of us who are never off the clock:

Why Future Holds More Stress

The bad news is that real-time is not going away. We are not going to settle for less than right now. This means that the future holds more and more stress. As we evolve into a society that demands more information and more information processing immediately, we are also evolving into a society of people under constant stress. The fact that computers are ubiquitous is making it all that much worse. Of course people were stressed last century as well, but in the seventies when you went home for the weekend you, relaxed. Nowadays? No way. There is no 30 minute period in my life that I do not check email. Going off the grid is really hard for many of us. Real-time is not only stressful, it is addictive.

Faster causes stress. So does the non-stop flow of information. When we are unable to fall asleep at night, we lie down stressed and thinking why? Why am I doing all of this? The tough part is that there is no other way. We do not know how to do what we do and not be stressed. So for better or worse, we are rushing forward through the sea of information towards more stress.
