My mother just recently passed from ALS and after her passing 2 of my father’s friends reached out and talked about their parents and their demise to the disease. My dads friend’s wife, who’s in her 30’s lost her dad in 2006 and while conversing with her, she told me back then she looked around for causes and somehow traces it back to him being heavily involved in botanical research. I’m not sure if that’s the right field of study. Anyway my mom passed within a year of this disease, a month and a half before her symptoms started she accidentally cut her thumb pretty deep, like bone slightly visible deep. She had a green thumb and loved gardening, tons of indoor and outdoor plants she’d spent the last 10 years taking care of passionately. Anyway she was of course, with her open wound still caring for her plants at the time. So I’m just thinking maybe there’s a possibility that this disease may be something you could develop from plants. This is just a theory.
