Yes...I can attest to this although only tangentially, and anecdotally. This from the experience of knowing a former colleague....a veteran from the Vietnam era who suffered some ill effects of 'Agent Orange' (health issues, primarily evident as hair loss)....but nevertheless continued a career in aviation...as a pilot for a major airline. He also had a major investment in several McDonald's franchise restaurant locations....so, he was well set. Financially 'well set'...physically'? I lost touch with him........I mean....I only knew him casually in a working environment, then never saw him around...he was a millionaire (due to McDonald's)...so....dunno what transpired.
