Not a single email until now ? it's already twelve o'clock . I can't believe it !   Can't bear it , right ? I've been there before . I'll feel uncomfortable if no one calls me or sends me text messages , like there is something missing .   Yeah , that's right . If no one sends me text messages , I'll go crazy .   Actually , this is a kind of addiction called ' infomania ' or ' information overload ' .   Addiction ? checking emails and text messages often can be called an addiction ? no way !
