I worked at a nursing home for many years. One of our patients was an eighty-year-old man with a soothing voice. He often read to the others to put them at ease or help them get to sleep.
One night I noticed that his breathing seemed labored. He struggled a bit to inhale, and he emitted a rattling sound as he exhaled. The next day, he told me that he kept dreaming he was drowning.
He went to the doctor and got diagnosed with floppy larynx. They had to operate, and sadly, he lost his soothing voice. The change is permanent.
