The fact that you’re saying “most” and “many” not “all” is exactly what I mean. Yes, there are patterns and similarities, 100%. But some people stutter their whole lives, some develop them, and a few are even caused by injuries. Some people are helped with medicine or alcohol, where alcohol makes mine a lot worse. Some people are helped by talking slower, and then there are the blocks you just can seem to navigate around. Saying many people have the same experience, is like saying many people are blonde. If the treatment helped ALL blonde people, I’d still be screwed.
