Emails 'Pose Threat to IQ'

The distractions of constant emails, text and phone messages are a greater threat to IQ and concentration than taking cannabis, according to a survey of befuddled volunteers. The average IQ loss was measured at 10 points, more than double the four point mean fall found in studies of cannabis users.

Productivity at work was damaged and the effect on staff who could not resist trying to juggle new messages with existing work was the equivalent, over a day, to the loss of a night's sleep.

The most damage was done, according to the survey, by the almost complete lack of discipline in handling emails. Dr Wilson and his colleagues found a compulsion to reply to each new message, leading to constant changes of direction which inevitably tired and slowed down the brain.

That does it. I am going to get away from the computer and go light up a fat one. Better for my brain.
