Video explains why time speeds up with age

- A June 2 post on X from @TheUnreadWhy said time can feel faster with age because the brain processes familiar experiences more efficiently, while novel experiences demand more attention and can stretch subjective time. (x.com) - That idea lines up with a long-running finding in psychology and neuroscience: perceived time is not a direct readout of clock time. Researchers have repeatedly found that attention, memory density, and novelty can change how long an experience feels in the moment or in retrospect. Reviews in the field describe prospective timing as especially sensitive to attention, and retrospective duration judgments as more influenced by how much contextual change or memory content an interval contains. (x.com) - In plain terms, routine compresses experience. When days are filled with repeated, low-variation events, the brain has fewer distinct markers to encode, so periods can seem to blur together when you look back on them. By contrast, travel, learning, major life changes, or even taking a new route to work can create more event boundaries and richer memories, which can make time feel fuller or slower. (x.com) - Age is only one part of this. Researchers also link time perception to attention, emotional state, stress, and arousal. High-pressure moments can feel elongated in real time, while busy or distracted periods can seem to disappear quickly. That means the “time speeds up as you age” claim is better understood as a pattern in subjective experience, not a biological clock literally accelerating. (x.com) - The strongest version of the argument is not that older people lose the ability to perceive duration, but that familiarity changes how experience is encoded. If more of life becomes predictable, the brain may process it with less effort and store fewer vivid distinctions, leaving the impression that weeks or years passed quickly. (x.com) - The practical takeaway from the research is concrete: novelty matters. New skills, new places, unfamiliar conversations, and breaks in routine are all plausible ways to increase the amount of information an experience carries, which may make stretches of life feel less compressed in memory.
