A new study suggests that age-related changes in our brains may explain why time seems to slip away faster with every passing year. Researchers analyzed brain scans of 577 people watching an old Alfred Hitchcock episode, finding that older adults’ brains showed fewer transitions between neural states, making each event last longer. This aligns with Aristotle’s idea that more notable events occur in a given time period, making it feel like time is flying by. The study proposes that age-related neural dedifferentiation may contribute to this phenomenon. However, linguist Joanna Szadura notes that our internal time scale also plays a crucial role in shaping our perception of time, with both linear and nonlinear scales affecting how we measure time.
