Charles, I would take it one step further, Charles. It is the marketplace or the regulatory body that decides whether the individual is qualified for a given opportunity. For example... someone who is deaf cannot be qualified to fly a commercial airliner... but there is a Deaf Pilots Association out there made up of deaf folks who are fully qualified (by the FAA) to fly planes of a certain (limited) type into less highly trafficked (is that a word?) airports. As the technology gets better, the limitations get fewer! Dr. Jane Jarrow
