One should consult an automotive engineer for safer seat belts, a civil engineer for a better bridge, a surgeon for internal medicine, a computer programmer for hard drive problems, and Sarah Brady for firearms expertise.
HEHE. A surgeon wouldn't be the best person to talk to about internal medicine in general. They are generally out of practice for it because their specialty is surgery, not internal medicine (which includes treatment for TB, HEP A, B and C, etc.), and a computer programmer may not even know how to troubleshoot a bad HD, that what system administrators are for (they really are two different disciplines).
Point is still well made though. I loved this quote for what was wrong with it as much as what it intended to portray.
