I asked my pulmonologist about general anesthesia for an elective surgery. He was short, not so sweet, and too the point. Joe "only under the most extreme emergency should you have general anesthesia." "You are almost 77 years old, what can't you live with, that you haven't already lived with." A good, solid point. That is a doctor that cares, that is why I go to him.
This point is one you may want to look at for yourself or loved ones.
