I use internet mostly to get info . There is such a lot of info on the net, it is really amazing. I can definitely live without the blog sites, social networking,and all that jazz and never use them. After using internet in my quest for knowledge, I would say a definite "No". Any one can live without internet.Mankind had lived without all the present technology for thousands of years.But in the present scenario, where technology has become all pervasive and entwined in our day to day lives, can we afford to live w/o internet and take on to "the frog in the well " life. No.
