joshbuddy with due respect given your manifest ignorance lack on this subject then on what basis am I to accept your opinion of the verified Leadin language rather than my own opinion that the verified Leadin language is fine For goodness sake your previous edit asserted gross error on an extremely important subject one where continued health andor life have hung in the balance more than a few times   As for the rest of the article I do plan on addressing some pure opinion therein and to add verification where it is needed along the way Despite this future work and contrary to your opinion the current introduction does provide sufficient summarization for an encyclopaedic entry Before you tinker anymore with this subject I recommend you read a wide range of peer reviewed literature on the same subject Youll find the current verified introductory language to be consistent That you have not applied yourself to this endeavour already is manifest so I am not making any assumptions on this point This is a very serious subject deserving of a very high standard of presentation and substantiation
