List three examples of physical or mental problems covered by the American with Disabilities Act (ADA), and three examples of physical or mental problems not covered by the ADA. Write a summary of your findings. Also, argue either that the ADA has been appropriately interpreted and applied by the courts (in terms of the types of disabilities covered), or that it has not (for example, that it has been overly interpreted and applied to too many types of physical and mental maladies).
