As is shown in the picture above， a hand is tightly glued to a computer mouse linked to a personal computer by an iron chain. Clearly， the iron chain stands for the control of the computer over the person who indulges himself in the cyberspace. An implication from the picture can be figured out that the personal computer， a high-tech device originally created for saving time and energy so as to benefit humankind， ironically turns out to be a gadget murdering the time and energy of quite some people.
The personal computer worthlessly consumes the time of those addicted to it. A survey shows the average time spent on it of those addicted amounts to 16 hours a day. And the minimum continuous time spent on the personal computer is 12 hours， while the maximum soars surprisingly to 168 hour-a whole week！ Needlessly to say， the computer has eaten up their time for work， for sports and， worse still， their precious time for rest-an natural activity for refreshment to keep the body functioning normally.
The personal computer has also depleted their vigor. They survey finds almost all those computer freaks feel sluggish in their jobs as a result of staying too long before the computer. They also have lost their enthusiasms for outdoor activities. Some even become so feeble that they sweat when standing for a short while. It seems that they are being burned out by the high-tech monster.
The sole way for the addicts to restore the proper use of the computer relies on themselves. Only when they have a sound recognition that the computer is but a tool to facilitate their life instead of their master can they develop their self-control. If they can limit their time on using the computer within 6 hours a day， their life will be freed from the trap of the computer and will return to its track.
