When your ears stop functioning your world shrinks enormously. Imagine the walls closing in around you bringing a frightening darkness. Your eyes try to adjust to the gloom. Your sense of hearing struggles to catch any comforting sound, to no avail. Sounds are muffled, distant.
Fear overtakes any sensibility.
Fear of inability to communicate. Fear of appearing dull or dimwitted. Fear is often the driving force to action. With all the medical technology available to us now, you needn't suffer alone with the sensation of darkness. Turn that sense to sensibility.
