Whether we're calling out "Yo!" or singing "Figaro!" or just plain saying "Howdy," we expect our voice to be there when we need it.
Like breathing, we don't even think about it unless there's a problem. But by the time our vocal cords become so damaged they don't work right, it's often far worse than an inconvenience.
For some it can be a crisis, and that goes for more than just professional singers and actors. What good would coaches be if they couldn't shout? How about the voice of authority required by teachers, attorneys, broadcasters, clergy or parents?
