Ever considered this point: As an engineer, becoming insulin dependant diabetic has not cost me my career. It is annoying that I am not allowed in fuel tanks and not allowed to drive airside, but I have not lost any pay. What if a pilot gets this, or one of many other illnesses. It won't be an ADD for him/her. It will more than likely mean a career change. Perhaps this vulnerability warrants a higher level of pay to encourage people to become pilots.
