This is a place with the purpose of sharing information and opinions. The idea is to get others take on a subject.

I expect intelligent opinions, and debate based upon evidence and experience. I also stated that I had looked at it as I would a patient thus a functional exercise, not that it was the sole and sufficient answer to the question.
