I have hit retirement flying. Doing Europe every couple of years. Dad had to quit flying as does my father in law, only have about 10 years of travel left.
I still fly if I have to, but only CONUS travel. I don’t think I could handle anything longer than three hours, since I don’t like being closed in!
But oh, man! If I were even 10 years younger and had unlimited funds, you wouldn’t see me for dust. Wanderlust hit me as a kid and it has never left!
