Why Time Speeds Up As You Age

A summer at ten lasted forever. A year at forty goes in a blink. That is not nostalgia — it is a measurement, and something real has changed in how time gets encoded. This video takes the mechanism apart. Inside: Paul Janet's 1877 ratio: a year judged against the life already lived — elegant, and never actually demonstrated Adrian Bejan (Duke, 2019): perception as a stream of snapshots, and why the sampling rate falls as the body slows — fewer frames per second means fewer marks per month Novelty as compression: the first commute gets filed thickly, the two hundredth gets filed not at all The reminiscence bump: why memory concentrates between roughly ages 10 and 30, and why that stretch still feels longer than the last decade Why the folder for the last five years feels thin, and why that is a filing problem rather than a character flaw Six practical moves: change the route, act before the season is right, make the ordinary observable, keep one running ledger, break the anchors, expect the effect to run both ways The conclusion is uncomfortable and useful in equal measure: you cannot slow time down. You can only make it heavier, so that when you look back it is still there.
