I call this email syndrome, because I feel it and it occurs to me from time to time.
In nowadays, email, internet are part of our life, at least for me. For other so called “tech-head” or “modem tech-head”, facebook, tweeter etc will have to be added to their menu too. Everyday, we feels it a normal life with many emails, and accept the fact that majority of emails are useless if they are not entirely junk mails. We seems feel calm to clean up and prepare for more to come in next days. If we don’t receive any email in a day, we may feel a bit anxious, worry about we may miss out some ‘important’ thing. In such days, one email, even it may be a junk mail, would be a good comfort.
