Knowing all you can about any condition that affects you, a family member, or a friend is the first step in making sure the condition doesn't become a problem. The knowledge of how the body creates and uses insulin and what is needed to be done will help the diabetic live a normal life. The knowledge of how the joints work, what to do if arthritis sets in, and how to protect the joints will help the arthritic live a normal life. The knowledge of what happens to the aging brain, that nutrition and mental exercise help, and the signs of dementia will help the elderly have a longer, productive life. The same thing goes for stuttering. Knowing how to help yourself and where to go for help, practicing the techniques for better speech, and adjusting any poor attitudes will help the stutterer lead a more normal life.
