Cheat Sheet: Modifiable Variables Associated with Parkinson Progression

I recently gave a lecture at Tafara Farm outside of Negril, Jamaica and they warned me there wouldn't be internet or powerpoint available. I did my best to summarize the impact of different modifiable variables, relative to one another.
Comprehensive conversations about the possible hows and whys behind these associations can be found in www.Parkinson-School.com.

These charts present some very interesting information. However, where's the actual scientific data to support all of these claims?
