Mach 78, you are quite wrong about Tinstaafl's qualifications. His ATPL is most definitely thawed. In fact he now holds several ATPLs.
He is a professional health worker as well.
All he did was call you on the validity of a statement that you made. As a professional, he is entitled to do that. I am sure if you saw an inaccuracy on an issue that you would respond in a similar way.
I too have a scientific background and I would also question blanket health statements with little or no scientific proof.
You did offer help and that is great. Just, as with any advice on any forum, it may be challenged by others. There is no malice in that.
