I can beat your record; I flew the 146 for 19 years and never ever had a problem. Not only that, I am still in the rudest of health

That cause-effect is always available as a reason now that it has reached this stage of association via the internet.
I too was quite worried about my own health when I recently was strangely ill, what with many hours of breathing in engine oil fumes, burning Titanium dust transite dust, and last but not least vaporized lead fumes.
