Totally agree! Blocks are a severe form of repetitions. Suppose we repeat for example: mir - mir -mir -mirror. What would happen if we tried to continue speaking after the letter 'r' (of the word mirror)? (so instead of going back the the first letter 'm') I think the answer leads us back to blocks? (do you think so too?) Let's say, we say 'mir' but we cannot seem to continue (so we go back to the first letter), then we would have blocked if we continued speaking after the letter 'r'. But then why do we stutter? We do blocking to prevent repetition. We also do repetition to prevent blocks (as I just explained). ​ So it's a cascading loop, we are in a vicious never ending circle and we don't acknowledge that we act in this way. So we are stuck. Therapies, even psychologists are unaware of this so no one has even tried to deal with this loop. How do you think about this?
