Stuttering, or stammering as it's also often called, is a neurological condition based on the brain鈥檚 wiring that affects more than 70 million people worldwide. A three to four-day course called the McGuire Programme is trying to help people overcome stutters using a mixture of physical and psychological methods. Lifelong stutterer Dave McGuire founded the course in 1994. It has a demanding routine but the techniques have led to life-changing progress for many people.
