Thinking of having brain surgery?

Don't go to the Rhode Island if you do. A hospital there has performed brain surgery on the wrong side of the brain THREE times this year. Two patients were "ok" after the goof up and one died. The hospital was fined $50,000 and reprimanded by the state Department of Health. They are now "re-evaluating their policies".
Just how hard is it to operate on the correct side of the brain? I mean it's not brain surgery err rocket science or anything. Your biggest problem should be knowing what to do once you are inside the brain, not knowing which side to operate on, thats the easy part! After the first wrong side operartion you would think they would be extra careful. Use a sharpee and write "Operate here" on the correct side and "Not here" on the other side if you can't keep it straight. Shesh.
