I have so far kept Facebook at bay, and now the researchers at Edinburgh Napier University have proved me right, by discovering that it makes students stressed. Indeed, the more time people spent on Facebook, the more anxious they became: the guilt of turning down a friend request, or of not properly managing the ones they already had, began to oppress them. Then there was the ghastly pressure to be “entertaining”, and the insidious soul-worm of “friend envy” in response to those who seemed to be having a more fabulous, popular time on the site.
