Acceleration of subjective time with age
I think that from an experimental perspective, the subjective passage of time being faster in later life is somewhat true, but not as simple as the above, and only on a decade-scale, not a minute/hour/day-scale. The results tend to depend on the methodology; in particular using metaphors may produce different results than using a Likert scale. Also even this weak effect of age appears to cap around the age of 50. Furthermore being under time pressure (presently or during the period in question) significantly skews the answers (towards faster passage). So it's a pretty complex topic.
