People who lack a specific sense compensate by developing their other senses to fill the void. As such the blind hear things differently from the rest of us, while the deaf see things in way we do not. Inasmuch as those of us think this lack of sense is tragic, the perspective it affords folks is immeasurable.
This reality extends to those of us who are not as privileged to be wealthy, or of good health, or a part of a loving caring family. Yet the perspective it affords, as I learnt in a recent discussion, cannot be fully understood until we make contact with it.
