My name is Peter Louw. I am an ex-patient and unashamed admirer of Dr Martin F Schwartz, of the National Center for Stuttering in New York (www.stuttering.com) who believes that stuttering is the learned result of the vocal folds' hypersensitivity to stress in 1 - 2% of people. Maybe he, too, is a crackpot, but I have been doing his Passive Airflow Technique for 30 years and it has helped me much. Presently I am developing a blog on this issue at http://stuttersense.blogspot.com. Looking forward to more of your stimulating blogs. Keep up the good work!
