Have you used Botox or had plastic surgery. Have you been depressed or been treated for mental illness. How much do you smoke or drink. Doctors are supposed to be nosy.

And how about your marriage € or marriages. And doctors take the Hippocratic oath, pledging to hold sacred their patients' secrets. One might well ask whether medical privacy is just. Ever had a sexually transmitted disease. Have you ever used marijuana or cocaine.

Physicians are trained to peer into your life, past and present, and ask all sorts of sensitive, if not uncomfortable, questions. You get the gist; the experience is intrusive. But the doctor-patient relationship was never meant to be other than confidential and privileged and solely for the benefit of the patient.

Patients expect it, or they would not be forthcoming. It's not just that they examine your naked body inside and out and record all its imperfections.

This pledge of confidentiality, however, is now challenged by a world where computers rule and health information falls into many hands.
