If you are “able-bodied” or without impairments, how would you like to roll a mile or for a while in my wheel chair? Wear a blind fold to perform regular routines? Use plugs to deafen or eliminate sounds in your ears? Hear sounds in your head that others do not hear? Endure “invisible” disabilities which are called into question because you do not use a cane, walker, or a wheel chair? You would quickly learn, as I have, the difficulties of negotiating when there are barriers – whether to structures, programs, technology, or services.
