I very very very much recommend this videohttp://www.lctglobal.com/Media-And-News/Videos/
diabetes = pd
insulin = dopamine
hypoglycemia = off periods
for diabetes this procedure seems to work. its hard to think of any reason why pd should be different. and many other diseases.
video also includes views of auckland, cute pigs and Mayor Tim Shadbolt of Invercargill saving the world. perfect.
