Web surfing is in danger of becoming an obsession for many Americans, with only one-fifth of a recent survey feeling they could go for longer than a week without going online. 

A staggering 15% can't go a day without surfing; 21% can hold out for just a couple of days; and 19% wouldn't be happy after a few days offline.
In fact, 48% of US adults feel something important is missing if they don't have Internet access, according to the survey by ad agency JWT.
In a shocking finding, almost 30% of respondents spend less time socialisting face-to-face in favour of being online. And 20% admit to having less sex because they'd rather be on the Web.
The Internet was ranked as the most important device in people's lives, followed by the mobile phone and then television.
