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.

Of the five senses, hearing plays one of the most important roles. When it begins to fade, your world begins to fade too. From the darkness, medical advances have moved into the light-years bringing with it hope and help for myriad health problems.
