Finding a cure for disabilities is not normal. Positive self esteem, and well adjusted attitude toward self is normal. Belief that one is inferior simply because one is different is not normal. It is a self destructive pattern of thought.
So the doctor who invented CI is not normal? So Dr. Clark is not normal? No wonder, I had a feeling that he wasn't happy about the fact that his father is deaf.
I get what you mean by that. I see that you mean that a person who is not at peace with his/her disablity is not going to be a happy person. One gotta make peace with the disability in order to be relaxed about life.
