Why Days Feel Shorter As You Get Older

Have you noticed the years going faster? When you were a kid, a single summer felt endless. Now a whole year can slip by before you've caught up with it. Same amount of time, completely different feeling. There's actual science behind this. In this video we get into why it happens, using the work of people who've spent careers on it, David Eagleman, Adrian Bejan, and Claudia Hammond. A big part of it comes down to memory. When everything is new, your brain records a lot, and looking back, that stretch feels long. Once life settles into routine, fewer new memories get made, and the same amount of time feels like it barely happened. That's why a familiar year can vanish while a two-week trip somewhere new feels enormous. Psychologists call that last one the holiday paradox. We also look at the dopamine clock idea, where your brain's reward system quietly shifts how fast time seems to move. And the reminiscence bump, the strange fact that most of us remember our teens and early twenties more vividly than any other stretch of life. So if you've ever wondered where the time went, this video is for you.
