Thanks, Charlie, for your clear explanation re causes of death, precautions against complications and what is responsible and whether in the long run it really matters whether or not the primary illness is responsible. I was serious in my query: Several times I have encountered statements saying nobody dies of Parkinsons. It seemed to me that that is open to interpretation. If Parkinsons causes difficulty swallowing and I aspirate some food and get pneumonia and die, the actual cause is pneumonia, but it seems to me the cause is Parkinsons. If a homeless person starves to death, they die of starvation, but the causative factor is being destitute. Right? Liz S.
