From what I understand no one really knows what causes Parkinson's and until one is diagnosed with it most probably don't give it a thought. However, if genetics play a role (as suspected)...perhaps we'll see a new generation of smokers eventually when younger family members are exposed to older relatives who were/are afflicted.
Wouldn't that put the die-hard anti-smoker's panties in a twist!!
