"I have read that if you live long enough you will get Parkinson's disease."
bullhooey, IMHO. "they" say that about cancer, arthritis, and just about any modern degenerative disease.
"they" say that we live longer now. Bullhooey again. The #'s are skewed because of the relatively high numbers of people that died in childhood...died of infectious diseases, etc. That was actually a GOOD thing because only the strong survived...but I digress.
