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

✈️A six-week summer holiday once felt like its own geological era. Now whole years slip by and you cannot put the months back in order. The strange part: a year is exactly as long now as it was when you were eight. The clock never changed — you did. This video breaks down the three forces speeding up your sense of time, and the one you can actually do something about.

The first is over a century old. In 1877 the French philosopher Paul Janet pointed out that we measure time against the amount we have already lived — so to a five-year-old a year is a fifth of everything, while to a fifty-year-old it is a thin shaving off an ever-growing block. Your year didn't shrink; your ruler got longer. The second, and best-evidenced, is memory: your brain records change, not clock time, so childhood's wall-to-wall firsts are dense in memory while routine adult years compress into a gray smear. The third is more radical and contested — Duke engineer Adrian Bejan's 2019 argument that the aging brain literally processes fewer mental images per second, like a camera dropping from sixty frames to twenty-four. Stack all three and the acceleration is not laziness or a failure of attention — it is the predictable output of how a human life and a human brain actually work. Finally, the one lever in your hands: novelty. Deliberately breaking routine lays down a thicker record and stretches time back out — no grand gestures required.
