Can we live without Computers?

This topic came out to my mind when our computer teacher asked this question in the classroom. The answer was of course yes there. This thought then struck my mind can we really live without pc? All the comforts and standards will be gone. Well I had a tough time living without internet for just 7 days but without my computer…. Its something I would rather not try :D.
Ok logically speaking, we need air, food, shelther, energy and blah blah all the things to live and a balanced environment. So there is no computer there… nor it existed on early stage of human evolution and life. So its proven we can live without computers. So why am I bringing this topic? Am I insane? Well may be I am. But its worth a mentioning since the computers have been like the blood and bone for human beings. Everything we do, the computer has got involvement. So it is a thing that fascinates life not runs it. We human beings can live without comforts can’t we…. After all we are social and intelligent, what can a silly box do to us? And even science has proven we don’t need computer to live….
Well that’s logical and theoretical. Now imagine a life without computers, no speedy vehicles, no word and other application, no music players, no facebook and internet . That’s not all, think of other application and things you do and how much computer is involved in it. Now remember John Lennons Imagine and try it with computers…

Imagine there's no Computer
It's not easy even if you try
No means to comfort us
Only the human brain and muscles
Imagine all the people
Living for today
Running without vehicles
Calculating without calculators
Animating without Software
It clearly indicates we all are so much used to computer and its comforts. And I certainly would not want to take any risks by not using the computer for a month or so. (anyone dares to try lol). So you can argue that a human can survive with its intelligence and the nature. Maybe they can, I kno it would be very difficult for me if I do manage to survive somehow. Still the question arises how would the human life be without computers. Can we just leave all the comforts and work our heart out? Are we still energetic and active? I guess not. We will certainly struggle without computers in the current era. I love my PC, I have to get daily dose of computers lol I simply do…. So wat I do conclude is that without pc humans can hopefully survive but their mind will be so dull that they wont seem like a living being. I remember a Korn Song here.. pardon me… its titled dead bodies everywhere (offtopic – listen to it :D)…. The human beings without pc might be something like that…coz there will be no communication and no huge work and certainly no development and its like living in a casket only. Your free to argue my points……. Would love to hear you :D
