My grandfather was a crop duster pilot in the 60s-70s. He died of Parkinson's almost 4 years ago today. He is the only one in my family to succumb to this disease. For a brief moment I was relieved to know there was some explanation for his suffering.
Then I read the HN comments. It is beyond infuriating to read a well researched paper with 1300 open cases legal with overwhelming evidence only to be met with "zero chance this is real."
