🦒Why Time Speeds Up as You Get Older⁉️ #psychology #neuroscience #time #memory #brain

Think back to a single summer when you were a child. It went on forever. The afternoons had no bottom. A six-week holiday was its own geological era, and September was so far off it barely counted as real. Now think about last year. It is just gone. You cannot put the months back in order. You blink and it is December again, and you hear yourself say the line everyone past Here is what makes it strange. A year is exactly the same length now as it was when you were 8. 365 days. The clock did not change. The calendar did not change. The only thing that changed is you. The easy answer is that you are simply busier now. More responsibility. Less attention to spare. That is true, but it cannot be the real reason, because the acceleration does not stop when you retire and the calendar empties out. Something deeper is going on. In fact, three things are happening at once, and the third one is the only one you can do anything about. The first reason is over 100 years old, and once you hear it, you cannot unhear it. In 1877, a French philosopher named Paul Janet pointed out something almost too simple to seem profound. We do not measure a stretch of time against a clock. We measure it against the amount of time we have already lived. To a 5-year-old, one year is a fifth of everything they have ever experienced. A vast, unrepeatable slab of life. Of course it feels enormous. To a 50-year-old, that same year is 1 50th of a life. The same 365 days, laid against 5 decades of memory, is a thin shaving off an ever-growing block. Proportionally, it is 10 times smaller than it was for the child. So the year did not shrink. Your ruler got longer. And you can feel it in the gap between birthdays. As a kid, the wait from one to the next was an ocean. Now they seem to arrive stacked almost on top of each other, as if someone keeps quietly moving the line closer. By this logic, time was always going to compress, and the years still ahead of you will be the smallest fractions yet. It is elegant, but it cannot be the whole story, because it predicts smooth, gradual squeeze, and that is not quite how it feels. It feels like some years vanish while others stretch. For that, you have to look at memory. Here is the part with the strongest evidence behind it, and the part you can actually use. Your brain does not record time evenly, like a camera running at a fixed speed. It records change, newness, the first time, the unfamiliar place, the thing you did not see coming. Those get written down in high resolution, dense with detail and timestamps. Routine gets the opposite treatment. When today is a near copy of yesterday, your brain has almost nothing new to file, so it does not bother. It compresses the repetition down to nearly nothing, because nearly nothing happened that it had not already stored. This is the real reason childhood feels so long in the rearview mirror. Almost everything back then was a first. First ocean. First bicycle. First day at a new school. First time staying up past midnight. Childhood is wall-to-wall novelty, and novelty is dense in memory. Adulthood quietly turns automatic. You have done most of it before. Same roads, same job, same faces. So your brain stops taking notes, and whole months collapse into a single gray smear you cannot itemize. You can prove it to yourself with one observation. A single week somewhere new, a trip, a strange city, can take up more room in memory than the two ordinary months that came before it. While it was happening, it was packed with firsts, so your brain laid down a thick, detailed record. Look back, and that one week looms larger than 60 ordinary days. The routine years are not actually shorter. They just leave almost nothing behind to remember them by. And then there is a third idea. More radical, more contested, but worth knowing. In 2019, an engineering professor at Duke University named Adrian Bijan proposed that the effect is not only about math or memory. It is partly physical. His argument, which not everyone in the field accepts, runs like this. What we feel as the passing of time tracks the rate at which the brain takes in new mental images. Young brains process images fast. Lots of frames per second, so to speak. Densely packed perception. As you age, Bijan argues, the hardware slows down. Neural networks grow larger and more tangled, so signals have to travel farther. Pathways degrade. Even cicades, the rapid little jumps your eyes make to gather visual information, happen less often. Fewer snapshots reach the brain in the same span of clock time. Think of film shot at 60 frames a second versus 24. Play them back side by side, and the high frame rate version looks smooth and full, every motion rendered in detail. The other skips and rushes, like it is hurrying to get somewhere. By Bijan's account, your younger self was the high frame rate camera. The same hour simply held more moments inside it. It is an elegant theory, and it is still an open argument, so treat it as a fascinating possibility rather than settled fact. But notice that it points in the same direction as the other two, so stack them up. Proportionally, each year is a smaller slice of a life that keeps getting longer. In terms of memory, the more your days run on autopilot, the less your brain bothers to keep. And possibly, the aging brain literally samples reality at a lower frame rate. All three push the same way. Time speeds up as you get older, and that feeling is not laziness, not a failure of attention, and not all in your head. It is the predictable output of how a human life and a human brain actually work. So what do you do with this? You cannot argue with the proportional math. You probably cannot slow the hardware, but the memory factor, novelty, is almost entirely in your hands, and it happens to be the strongest lever of the three. If routine compresses time, then deliberately breaking routine stretches it back out. This does not take grand gestures. You do not have to quit your job and travel the world. The brain responds to genuine novelty at any scale. Take the road you do not normally take. Learn something with a real learning curve, the kind that makes you slightly bad at it for a while. Have the conversation that might go somewhere you did not plan. Put yourself, on purpose, and often, in situations where you do not already know how they end. Every one of those hands your brain's something new to encode. And the more it encodes, the thicker the record, and the longer that stretch of life will feel when you look back on it. There is a quiet sting in this, and it is worth sitting with. The sense that life is accelerating is, in large part, a readout. It is your brain reporting that not much new is coming in, that you have settled into the automatic, and the automatic does not get written down. You cannot add years to your life by paying attention, but you can, in the most literal neurological sense, add life to your years, by filling them with things your brain judges worth recording. The endless summers of childhood were not a trick of memory. They were simply full. So the real question was never why time is speeding up. It is what you are still letting yourself do for the very first time. If you found this interesting, I will see you next time.
