My first symptom happened when I was 17 years old back in 1957. I am now 80 years old and with the except if the things damaged by CS, cochleas, semi-circulars and some vision, I am the healthiest 80 year old my doctor has ever seen. If you have CS the chances are it is not going to be the cause of your death. Just plan your life around your symptoms. N. Rainey Santa Cruz, CA
