A pilot is not past his "best by date" because he reaches 60.
Some of us are in good health (in fact, it seems the "cockpit slumps" occur to younger folks.. according to a recent research) and wish to go on past 60.
Unions with all of its evolutions and convolutions is just not my thing.
That said, the dude at AC benefitted from all the advantages of CALPA for a few decades... he should not complain much.
