There is a brain disorder out there called spasmodic dysphonia. The symptoms vary a bit from person to person, but if you’re diagnosed as a dysphonic spaz then the part of your brain that allows you speak properly has basically shut itself off. Permanently. There is no known cure or treatment.
Scott Adams, the guy who made Dilbert, was one such spaz… until after 18 months of suffering, he found a way to cure himself in two days.
That’s pretty great.
If I ever spaz out in a dysphonic manner, I will know what to do.
