It’s  not unusual to hear people who have undergone sympathectomies describe  themselves as feeling emotionally “colder” than before. Among  psychologists and neurologists alike there is concern, but no evidence,  that the procedure limits alertness and arousal as well as fear, and  might affect memory, empathy and mental performance. Professor Ronald  Rapee, the director of the Centre of Emotional Health at Sydney’s  Macquarie University, says he’s counselled several people who complain  of feeling “robot-like” in the long-term wake of the operation. “They’re  happy they no longer blush, but they miss the highs and lows they used  to feel.”
