The experience of time has been a long-standing interest of mine. Most research focuses on short periods, like seconds/minutes, affected by emotions etc. There's not much afaik on how we experience years and decades.
Long-term memory is under-theorized. At personal life level I think I experienced an 'end of history' moment when I went free agent almost exactly 8 years ago. But it feels like yesterday. OTOH I remember 2001-2011 as a much more coherent 10 year story story. That's atemporality.
