As the web expands with ever more content and information everyday, more and more people are getting addicted to the internet. The majority of US adults feel that they cannot go for a week without going online and one in three giving up friends and sex for the web. A survey asked 1,011 American adults how long they would feel OK without going on the web, to which 15 per cent said a just a day or less, 21 per cent said a couple of days and another 19 per cent said a few days. Only a fifth of those who took part in an online survey conducted by advertising agency JWT between September 7 and 11 said they could go for a week. "People told us how anxious, isolated and bored they felt when they are forced off line," said Ann Mack, director of trend spotting at JWT, which conducted the survey to see how technology was changing people's behaviour. They felt disconnected from the world, from their friends and family." The found the use of mobile phones and the internet were becoming more and more an essential part of life with 48 per cent of respondents agreeing they felt something important was missing without internet access. More than a quarter of respondents - or 28 per cent - admitted spending less time socialising face-to-face with peers because of the amount of time they spend online. It also found that 20 per cent said they spend less time having sex because they are online. We're turning into a world of Internet Addicts.
