Why Time Feels Faster as We Age

C1-C2 Level | 50 minutes | 5 Key Expressions

Where Did the Time Go?

When you're 5 years old, one year is 20% of your entire life. When you're 50, one year is just 2%.

Remember when summer vacation felt like forever? When a school year seemed to drag on endlessly? When waiting for your birthday felt like torture because it was so far away?

Now? Years blur together. Months vanish. You blink and it's December again. "Wasn't it just New Year's?" you ask yourself, confused and slightly panicked.

This isn't your imagination. Time genuinely feels like it's speeding up as we age—and there's fascinating science behind why.

The Proportional Theory: Duke University psychologist Adrian Bejan explains that when you're 10 years old, one year represents 10% of your entire life. It feels significant because it is significant. But when you're 50, one year is only 2% of your life—a much smaller proportion. Time feels faster because each unit represents less of your total existence.

The Novelty Theory: Research from neuroscientist David Eagleman shows that our brains encode memories differently when we're experiencing something new versus something routine. When you're a child, everything is new—your first day of school, first bike ride, first movie, first everything. Your brain creates rich, detailed memories. But as an adult doing the same commute, eating the same breakfast, attending the same meetings... your brain goes on autopilot. Fewer new memories = time feels compressed.

Studies show that people consistently underestimate how much time has passed as they age. When asked to estimate when an event occurred, older adults are more likely to say "just a few months ago" when it was actually several years.

Here's the paradox: in the moment, time can still drag (waiting in line, boring meetings), but in retrospect, years feel like they flew by. This is because retrospective time perception is based on memories, and when your days are routine, you form fewer distinct memories to mark the passage of time.

Research by psychologist Claudia Hammond found that 40% of people over 40 say time passes "much faster" than when they were young. Only 5% say it passes slower. The acceleration seems to peak around age 60-70.

The good news? You can slow it down. Breaking routines, learning new skills, traveling to new places, and creating novel experiences all help your brain form more memories—making time feel slower in retrospect.

Think About It:

  • When was the last time a year felt long to you? What made it different?
  • Can you remember summer vacations from childhood? How did they feel compared to time off now?
  • Have you noticed time speeding up as you've gotten older?
  • What's the longest period of your life that now feels like it passed in a flash?

Talking About Time Perception

Click each expression to see how it's used

1. "Time flies when..."
Formality: Neutral/Informal
Meaning: Time seems to pass very quickly during certain activities or periods. Often followed by "you're having fun" but can describe any situation where time feels fast.
Example:
"Time flies when you're busy at work. I can't believe it's already December—I feel like we just started this project in September."
NOW YOU TRY:
Complete this: "Time flies when..." Describe a situation where time passes quickly for you.
2. "Before I knew it..."
Formality: Neutral
Meaning: Something happened so quickly that you barely realized it was happening. Emphasizes how fast time passed or how suddenly something occurred.
Example:
"I moved to this city for a 'temporary' job. Before I knew it, ten years had passed and I'd built an entire life here."
NOW YOU TRY:
Think of something that happened faster than expected. Say: "Before I knew it, [X amount of time] had passed and..."
3. "The years blur together"
Formality: Neutral
Meaning: Different time periods become hard to distinguish from each other; you can't remember what happened when because everything blends together. Common when life is routine.
Example:
"When I look back at my 30s, the years blur together. I was working the same job, same routine—it's hard to separate 2015 from 2018 in my memory."
NOW YOU TRY:
Have you experienced a period where time felt like a blur? Describe it using this expression.

4. "In the blink of an eye"
Formality: Neutral
Meaning: Extremely quickly; in an instant. Used to emphasize how fast time passed or how suddenly something changed.
Example:
"My kids were toddlers, and in the blink of an eye, they're teenagers. Everyone warns you it goes fast, but you don't really believe it until it happens."
NOW YOU TRY:
Think of a change that happened surprisingly fast. Say: "In the blink of an eye, [something] changed from [X] to [Y]."
5. "Where did the time go?"
Formality: Informal
Meaning: A rhetorical question expressing surprise or confusion about how quickly time has passed. Shows you can't account for where the time went.
Example:
"I graduated from university 15 years ago. Where did the time go? I still feel like I'm in my early 20s, but somehow I'm approaching 40."
NOW YOU TRY:
Think about a period of your life that went by quickly. Ask yourself: "Where did the time go?" and answer.

This Week:

Pay attention to how time feels. Notice when it flies and when it drags. Try breaking your routine in small ways—take a different route, try a new restaurant, learn something new. See if it affects your perception of time's speed.

Remember: Time feels faster not because it is faster, but because we're forming fewer memories. The solution? Live more memorably.
