Recent Stanford University study of internet addiction showed, (according to slashdot) that interviewed 2513 adults in a US survey, nearly 14% of them said they found it difficult to stay away from the internet for several days…and “Approximately 6% also said their personal relationships had suffered as a result of excessive internet usage.”
I guess this percentage would be much higher on wider scale of geo- survey (apart from States). Ask yourself how many hours do you spend on the internet (for any purpose)?
