Here’s a reason you might not have thought of to get your flu shot this year – it might protect you from getting Parkinson’s Disease.
I’ve been saying since about 2007 that most late-life diseases can be pinned down on specific combinations of genetic susceptibility + external factors (in most cases, viruses). One of these was Parkinson’s disease, which looked like it was caused by Influenza.
Well, I missed it at the time, but this study came out in 2011: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3105060/
Next prediction: A surprisingly large number of cases of dental caries are caused by human herpes viruses 1 through 4. I expect this one to be confirmed some time around 2018.
