'A 39-year-old acoustic engineer who worked in a television studio for eight hours a day and six days a week for eight years went to see an ENT doctor after he felt the ground turn under his feet. He was also constantly ill at ease.
The symptoms did not have a pattern and the doctor was not able to pinpoint a diagnosis. The engineer was asked to go on a month-long vacation in the countryside -- sans most of the technology around him. When he returned, the symptoms had disappeared.'
