Oh, I’m there with you on the 2nd paragraph - on everything!
I’m longing for that day too, but at the moment, with some of my shifts starting at 4am, and others finishing at 1am it’s just a dream.
(Oh and I’m the same age as you lol)
I feel for you. During my main career, working nights/shifts was par for the course, never want to go back to that
