I’d wondered if you have a particular affinity for the mid-sixties. You were born in 1969. There’s a psychological theory that says what we tend to be most nostalgic for is a period in time that is several years before our own birth—when our parents’ romance might have been at its peak. The technical term for the phenomenon is “cascading reminiscence bump.”
This is a pretty interesting idea and as someone born in the early nineties, I definitely find aspects of the 80s to be appealing, especially when it comes to tech and sci-fi. I wonder if this phenomenon could be linked to the popularity of cultural trends in general.
