Parabellum, my comment was a "tongue in cheek" but on a serious note, I am sure the regulatory bodies would suggest that at " advanced ages" the crew have more frequent medicals etc. Technically if the age was raised to 70 then at 69 a person could start a type rating and OCC course, maybe do ditching and slide drills, flight deck window escapes etc.. is this really a sensible proposal? 65 is more than enough for most guys..I know from our company experience the guys over 60 tend to have longer periods off sick with " degenerative issues" , eyes, bones, bladder problems, kidney stones, back problems etc.. this is natural and not career related but the airlines have a choice to tolerate this or not, of course in the " civil service" it is expected!
