warned recently.

      Psychotherapist (采用精神疗法的医生) Andreas Herter estimated that there were some 380,000

sufferers in Germany. Herter based his prediction (预测) on the growing number of manic mobile phone

users among patients arriving at his Hanover clinic (诊所) for addiction treatment.

a married couple could only communicate by text message, even when they were sitting side by side.
