Imagine going for a day without access to the internet. If the thought makes you nervous, depressed or is just downright unthinkable, you might have a serious problem.
From social networking to researching assignments, there is no doubt that the internet plays an important role in almost every Hongkonger's life.
But, for some people, it's more than just a tool to keep in touch with their friends or to grab a few fast facts or references for that last-minute essay.
Addiction to anything, be it drugs, shopping, alcohol, gambling, or constantly messaging people on Facebook, is a problem. But, with a significant increase in internet addiction and the sometimes bizarre methods of dealing with it, people are becoming more aware that this is a social issue.
In 2005, a 28-year-old man collapsed and died from exhaustion after a series of long gaming sessions. And in a survey of Hong Kong youths aged between 10 and 18, almost half show signs or symptoms of internet addiction.
Discussions on the radio about these problems are common. For example, a talk show in August hosted by RTHK Radio 2 discussed problems that parents face when dealing with teens that have symptoms of internet addiction. The show also discussed the effects it has on these teens, such as an unwillingness to do homework. Another radio show, the 908 programme, also discussed topics related to the internet, such as problems concerning online relationships and addiction to online social networking services.
This growing awareness of the problem has spawned numerous services that claim to help those affected. Some are more successful than others - and some go to extremes.
