Try and enjoy your final trip as much as possible, I picked a four sector SIN-AMS-JFK-AMS-SIN for my final run. Chatted up the hotels in advance and managed an even more superior room. Unbeknown to me my wife arranged a good photographer with airside clearence to do the whole caboodle in AMS, still photography. Check-in, briefing, the final walk down the jetway, external, flight deck, a/c departing so I have a permanent record. Once retired stay involved if you can, airshows etc. and other volunteer work, stay busy.
Sorry, considerable thread drift!
