Just curious Have you meet someone or see somewhere, person who are blind also stammers or vice versa . And in some cases blindness can be cured , so is stammering also get automatically cured with it. ? Or a person who stammers, unfortunately goes blind , would they still stammers or not? stammering is linked with factors like our surrounding environment , behaviours and conditions, what we see, perceive etc and blind person, in most cases unaffected by these factors.
