The colorful Internet draws us to computers and brings us joy and wealth. However, it is also affecting our health, because of increased computer use. Some people humorously call these negative effects the "six destructive fists of the Internet".
    First, it damages the eyes. However good your monitor is, whether it is low-radition or LCD, you will definitely feel light-headed after a day of web-surfing.
    Secondly, it damages the hands. The constant repetitious movements will make your fingers and wrists sore and aching.
    Thirdly, it damages the mouth. When people are roaming in the sea of the Internet and chatting with the keyboard, the mouth is the most unused organ.
    Fourthly, it hurts the back. People will sit motionless in front of computers for several hours. Their midsections and skeletal systems suffer the most.
    Fifthly, it damages the stomach. It is almost impossible for web-surfers to have healthy stomachs. They always eat very simply. Sometimes they will have a sleep first, instead of eating anything.
    Lastly, it damages the liver, which is the result of irregular periods of sleep and an unhealthy diet.
    Although the "six destructive fists of the Internet" is only the nickname by web-surfers for their discomfort, it reminds us that we should not neglect our health when addicted to the vibrancy, high speed and efficiency of the Internet.
    The attraction of the Internet is irresistible. However, addiction to it will damage our physical and mental health. In fact, the Internet and computers themselves can’t cause the discomfort in our body. We should use computers reasonably to keep up with the Internet healthily.
