Posted By Kevin Heywood This may seem to be a long shot but I remember someone telling me recently that they had heard that people who stare at computer monitors all day - for example call centre staff - are more likely to have an accident on their way home because they have lost their ability temporarily to focus and concentrate. Does anybody know of any research or information on whether or not this is true? Thanks for your help.
