this is quite an interesting story and will probably challenge or provide conviction for several beliefs.
Woman resumes talking 20 years after injury
HUTCHINSON, Kan. - — For 20 years, Sarah Scantlin has been mostly oblivious to the world around her — the victim of a drunken driver who struck
her down as she walked to her car. Today, after a remarkable recovery, she can talk again.
Scantlin's father knows she will never fully recover, but her newfound ability to speak and her returning memories have given him his daughter back.
For years, she could only blink her eyes — one blink for "no," two blinks for "yes" — to respond to questions that no one knew for sure she
understood.
"I am astonished how primal communication is. It is a key element of humanity," Jim Scantlin said, blinking back tears.
Life nearly cut short
Sarah Scantlin was an 18-year-old college freshman on Sept. 22, 1984, when she was hit by a drunk driver as she walked to her car after celebrating
with friends at a teen club. That week, she had been hired at an upscale clothing store and won a spot on the drill team at Hutchinson Community
College.
After two decades of silence, she began talking last month.

This particular case should also give hope for the Terry Schiavo case.
