Science has changed human life considerably. Machines are being invented which have made our lives very comfortable. These inventions have brought a revolution in the lives of people. No one can ignore the role of information technology in modern day life. Techniques used at the right time always bring positive change. However, mismanagement can lead to a horrible disaster. No doubt the information technology has turned life into a comfort zone, but its excessive use can be harmful. SYED ASAD RAZA, Lahore, December 9.
