Well....mine didn't. And I know many people who at around the age of 50 began having serious health problems. If it wasn't for modern medicine they would be dying of old age.
If they have 'serious' health problems, how long are their lives prolonged and what quality of life do they have?
My father died at a relativley young age of 64 from cancer. He was deemed 'cured" because he lived for 5 years after diagnosis. He died in the 6th year, and much of his final years was extremely difficult and painful.
OTOH my grandson was diagnosed with leukemia 4 years ago. Thanks to medical intervention he is now a healty (crosses fingers) seven year old. His illness has been very expensive! I am greatful my daughter had health insurance through her work. But face it - the costs wouldn't be so exhorbitant without lawyers and government.
