PD kills. I am 46 and there's plenty of research to show that a PWP my age can expect to have more than 12 years taken off the normal average life expectancy. People in their, say, 70s can expect to lose a few years. The terminal event is likely to be aspiration pneumonia but the it's fatuous to deny that the real cause was PD.
I believe that it's important to know the truth so that we can live and plan our lives accordingly.
