Workers looking to snatch a break from the usual humdrum of office life are turning to the Internet for a little mental work out. Two thirds of those quizzed in poll said they prefer to surf the Web when they want to take a break. The rest simply head for the coffee machine, water fountain, stationery cupboard -- or walk around aimlessly annoying everyone else. Almost 85 per cent of those surveyed agreed that taking mental breaks at work relieved stress. Four out of five people said it helped increase performance and productivity. Just under half of all those people who take their time-outs on the Web play games. Surprisingly, more women than men enjoy playing games online during their breaks. What's not surprising is that the research, commissioned by NabiscoWorld.com, has been published to coincide with the launch of a new gaming and entertainment site from the snack company. Don't that just take the biscuit? ®
