Thanks buddy. I gave it a quick read since I am on a hurry but these two catch my eye: ***Approximately 50% of individuals who stutter report at least 1 additional relative who stutters, as estimated across clinically ascertained cohorts \[7\]. However, because the heritability is substantially less than 100%, environmental risk factors must also contribute*** Most of people are 100% sure that stuttering happens duo genetics. And I get why. Stuttering run´s on family there is no doubt about that. But... ¿Does it make it genetics? ¿Could it be that there is some genetics contributing factors but also environmental? ***Social context drives stuttering*** ***Following this line of research might facilitate the rationale for cognitive behavioral therapy approaches to help control feelings such as insecurity, anxiety, self-doubt, shame, or anger.*** I loved this one. This paragraph try to explain why we don´t (most of us) stutter when being alone. I could not agree more. Cognitive behavioral therapy looking to change our wrong belief´s and to understand us from the emotional point of view could be benefitial to say the least. ***Unsolved mystery*** To this day and over 2000+ years (there is data of stuttering on biblical times) stuttering remains a mistery. ¿Why is that? ¿Is because is that of a complex problem that needs more time? I really don´t think more time will give the answer Maybe we are looking at the wrong problem. I don´t have the answer of course but we should be open to look at every door without judgment or previous assumptions. When we asume is 100% neurological and the only solution is a future pill we shut down other interesting doors. To close, I think stuttering remains a mystery because is dinamic, multiple and unique to every person. But we also have fallen into the error of working based of certain paradigm without questioning them on the first place. As Bruce Lee said: "Empty your mind. Be formless, shapeless like water"
