I am at total odds as to why anyone would wish to continue into their late 60s
To those who recommend retire and get a life I ask to do what? Folks are motivated by a lot of things, if it is to continue flying so what? It may just be that they still get a hell of a kick out of it. One PPRuner has just ticked 86 years and still working as a 737 sim instructor, and why shouldn't he? Live your own life and stop telling others how they should live theirs.
