N of 1, but my experience doesn't fit with this common explanation. Big life changes, travel, having kids... none of it has done a thing to disrupt a steady progression to a point where (around age 40) a year feels about subjectively as long as maybe three months did in high school. Started being noticeable around age 25 IIRC, and time's done nothing but keep getting faster. This doesn't revert, at all, when things get shaken up, not even temporarily. It's still "you know that place we went the other day... oh, shit, that was six weeks ago".
