Don't get me wrong: It may well be that Teresa C. Long, MD, MPH, FS does not exist, or is 'misguided' or an 'outlier' or bat**** crazy in fact. I just laugh that you presumably expect us to accept your assertions to that effect. The affidavit - fake or otherwise - acknowledges that correlation does not amount to causation. But it also explains - with some force in my view - who bears the burden of disproving causation, and why.
And the history of medical science is not typified by the unerring unanimity of opinion or the constant correctness of the opinions of the majority.
I have to reiterate that I doubt there are many pilots making contributions to these kinds of threads who've had anything to do with CASA Avmed.
