Have you ever noticed that when you were a kid, summer holidays seemed to last forever, but now they fly by in a blink? That feeling that time speeds up as we get older is something almost everyone experiences. Scientists think this happens because of how our brains handle memories and new experiences. When we're young, everything is fresh and new, so our brains pay close attention, making time feel long and rich. As we age, life becomes more routine and familiar, so fewer new memories are made. This makes time seem like it’s rushing past. Another reason is how we measure time in our minds. When you're five years old, one year is a big chunk of your life—one-fifth of everything you’ve lived. But when you’re fifty, one year is just two percent. So, each year feels shorter compared to your whole life. Plus, as we get older, our brains process things a bit slower, which might also change how we feel time passing. Together, these ideas help explain why time feels like it speeds up, even though the clock ticks at the same pace for everyone.
“A single year feels shorter as we age because it becomes a smaller slice of our entire life.”
Reflect
If your life were a book, how many pages would one year take up now versus when you were a child? What stories make those pages slow down or speed up?

When we are young, many experiences are new. Our brains focus more on these fresh events, creating lots of detailed memories. This dense memory storage makes time feel fuller and longer in hindsight. As adults, we often repeat the same routines, so fewer new memories are formed, making time feel shorter when we look back.
A five-year-old sees one year as 20% of their life, while a fifty-year-old sees it as just 2%. This change in perspective means that each year feels shorter the older we get. This is called the 'proportional theory' of time perception.
When life becomes predictable, our brain’s attention to the passage of time lessens. This makes intervals seem shorter because we’re less aware of time itself. This idea is supported by studies showing that people in unfamiliar or exciting situations often report time passing more slowly.
Research suggests that as people age, their brains process certain kinds of information more slowly. This could change how they experience time internally. Slower processing might mean less detailed perception of events, making time feel like it’s passing faster.

Perspectives
Enter a viewpoint. Notice what it reveals, what it leaves out, and whether it changes the question for you.
Scientists see the speeding up of time with age as a mix of brain function and memory. Our brains pay more attention to new things and slow down when things get routine. Memory plays a big role because more memories make time feel longer when we look back. Also, how we measure time in our heads changes. It’s a mix of biology and psychology.
