‘My life is amazing:’ A 76-year-old man who was paralyzed by polio at the age of six is one of the last people with an iron lung.

Paul Alexander, a 76-year-old man who has spent most of his life confined to an iron lung, exemplifies how the only limitations we impose on ourselves.

Paul recalls coming home one day when he was about six years old and telling his mother that he didn’t feel well. Paul had been a normal child up until that point. He was animated and enjoyed being around other children. “Oh my God, not my son,” Paul remembered his mother saying.
