Do you remember how long the summer holidays seemed when you were a child? Six weeks felt like forever. Today, the months seem to fly by. Christmas comes around almost before you’ve packed away the decorations from the previous year, birthdays seem to arrive with alarming speed, and before you know it, another year has gone by. So, what happened? Is time really speeding up?
Of course not. A minute is still sixty seconds, an hour is still sixty minutes, and a year still contains 365 days. What changes is not time itself but the way your brain experiences it. As we grow older, the brain records and remembers time differently, making the years seem to pass more quickly.
Your brain loves new experiences
Think back to your first day at school. You probably remember meeting your teacher, finding your classroom, making new friends and wondering what the year ahead would bring. Everything was new, exciting and a little uncertain. Your brain was working hard because it had never experienced anything quite like it before.
Children are constantly experiencing “firsts”—their first bicycle ride, first sleepover, first holiday, first music lesson or first day at high school. Because these experiences are new, the brain pays close attention and stores them in rich detail. Looking back, childhood seems full of memorable events, making that period of life feel much longer than it actually was.
As adults, life often becomes more predictable. We drive the same roads, work with the same people, shop at the same stores and follow much the same daily routine. The brain doesn’t need to work nearly as hard to process familiar experiences, so they leave fewer memorable landmarks behind. Looking back, weeks or even months can seem to have disappeared in a blur.
Life goes on autopilot
Have you ever driven all the way home from work and suddenly realised you can hardly remember the journey? You know you obeyed the traffic lights and arrived safely, but the trip itself seems to have vanished from memory.
That’s because your brain often switches to “autopilot” when performing familiar tasks. Instead of paying attention to every detail, it fills in the gaps automatically. While this saves mental effort, it also means those experiences are less likely to stand out when you look back on them later.
The fraction theory
Another interesting explanation is known as the fraction theory. Imagine you’re five years old. One year represents 20% of your entire life. By the time you’re fifty, one year represents only 2%.
In other words, each passing year becomes a smaller and smaller fraction of your life. Some psychologists believe this may partly explain why each year seems to pass a little faster than the last. Although this theory doesn’t explain everything, it offers an interesting way of thinking about our perception of time.
Can you slow time down?
Surprisingly, many psychologists believe you can—at least in the way you experience time.
The secret isn’t changing the clock; it’s giving your brain something new to remember. Travel somewhere you’ve never been before. Learn a musical instrument. Take a different route to work. Read a book on a subject you’ve never explored. Meet new people or take up a new hobby. Every new experience encourages your brain to pay attention, creating richer memories that make life feel fuller and, in many cases, longer.
Make more memories
This may be one of the simplest ways to make life feel less rushed. Instead of filling every day with the same routine, look for opportunities to experience something different. The change doesn’t have to be dramatic. Trying a new recipe, visiting a museum, learning a few words in another language or taking a walk through a different neighbourhood can all help create fresh memories.
Years from now, you probably won’t remember an ordinary Tuesday spent doing exactly what you always do. But you’ll almost certainly remember the day you tried something new.
The take-home message
Time doesn’t really speed up as we grow older—our experience of it changes. The more routine life becomes, the fewer distinct memories we create, making weeks, months and even years seem to pass more quickly.
Perhaps that’s why childhood feels so wonderfully long. Almost every day brings something new.
And perhaps the best way to slow life down is not to watch the clock more carefully, but to give your brain more reasons to remember today.
