Fascinating that some kids become fluent after 3 years.  I've heard of this and forgotten.  I can imagine them being so comfortable and not caring to such an extent that they don't think twice about it.  Or something in the brain was fixed?  Wow with all our technology, we can't check or do not know.   I am going to run a test and try to remember not to worry over the fear or doubt over the word, know I can say anything, and just end this precondition my mind steps into.  I will see if it's possible, why not, I just have to remember in the moment.   From your other post, you mentioned people being on stage, I just wanted to keep it to one thread going forward if possible so I didn't reply to that one until I read all your replies and it reminded me of when I was presenting, I didn't stutter.  I was shaking!  I became more afraid of shaking than anything else.  I remember i did the presentation but not stuttering, shaking and being nervous about that!  Why didn't that cause me to stutter!?
