Onepoll and Siteopia collaborated on a poll of internet users to collect statistics on internet addiction. Some of the troubling findings from this survey:

• "17% of men delete their browser history every day. Half would panic if their mum saw their browsing history."
• "90 minutes - the longest we can go without checking email, Facebook and Twitter."
• The average man spends 19 hours on online weekly and the average woman spends 14 hours online weekly.
