Why Does Time Speed Up As You Get Older?

Does time really speed up as you get older, or does it just feel that way? This deep dive into the psychology of time perception breaks down why a year felt endless when you were a kid and vanishes in a blink now, why your brain has no actual clock, and the one thing you can do to slow it back down. Time isn't speeding up. You're just keeping less of it, and this video explains exactly how that works. It opens with a scientist who threw volunteers off a 150-foot tower to test whether time really slows in a crisis (it doesn't, but fear makes your brain record so much detail that the fall feels longer afterward). From there it walks through the three real reasons the years accelerate. First, the oldest theory, written down by Paul Janet in 1877: each year is a smaller fraction of the life you've already lived, so it feels shorter by comparison. Second, and more powerful, novelty: your brain measures a stretch of time by how much it saved, and childhood is packed with firsts, which is why your sharpest memories cluster between 15 and 25. Third, a contested idea from engineer Adrian Bejan that your aging brain literally takes in fewer mental images per second, so each minute holds less. Line all three up and they collapse into a single question your brain asks all day: how much am I saving right now? The good news is the answer is partly in your control. Two of the three causes are just math and biology, but the biggest one, how much you save, runs on new experiences. A day that doesn't match the one before it is a day your brain bothers to write down, and a saved day is a longer day. The clock never changes. You do.
