Empaths have the ability to scan another’s energy for thoughts, feelings and possibly for past, present, and future life occurrences. Most empaths are unaware of how this really works, and have accepted that they are sensitive to other people’s energy.
Being aware of these things could greatly increase doctor-patient relationship. If a doctor is more personable, the patient will be more willing to listen to them. If the doctor has higher expectations of the patient (either in the procedure being done or recovery time) the patient will do better and try to meet those expectations. It's simple psychology, really.
