Why Time Seems to Fly By As We Get Older
Many people experience the sensation that time moves more quickly as they age. While this might feel like a personal quirk, there are neurological and psychological reasons behind this common phenomenon. Two primary factors contribute to this feeling: changes in brain processing speed and how memories are formed and retained.
The Brain's Processing Speed
In our youth, the brain is like a brand-new machine. Its neural networks are simpler and more efficient, allowing for rapid processing and transmission of information. This faster processing leads to the perception of time slowing down because the brain is registering more information within a given period. The feeling is, "So much has happened; it must have been a long time."
As we age, the neural networks in the brain become more complex. Signals must travel through a more intricate network to reach the core of the brain. This increased complexity slows down processing speed, causing the brain to feel like time is accelerating. Furthermore, the natural process of aging damages neurons, further impairing the speed of signal transduction. The brain then takes longer to process information, leading to the sensation that "time is flying by."
Memory Formation and Retention
The brain's information processing center constantly refreshes visual information, typically every 200-300 milliseconds. However, as we age, this refresh rate slows down due to aging. In younger years, the brain might refresh five times, gathering five sets of visual data. As we get older, it might only refresh three times, resulting in only three sets of visual data.
The brain also selectively stores memorable experiences. It tends to prioritize novel, stimulating, and vivid memories. In our youth, we encounter many "firsts," such as learning to ride a bike, first love, or unique travel experiences. These rich and detailed memories contribute to a sense of time having passed slowly because so much occurred.
As adults, our lives often settle into routines. Commuting to work, eating at the same restaurants, and the daily grind often lack the novelty that creates strong memories. Without these memorable details, time seems to blur and pass quickly, because we have less to remember and cherish.
Slowing Down Time: Injecting Novelty into Life
If you feel like time is accelerating and you want to slow it down, the key is to create more engaging and memorable experiences. By providing the brain with richer, more interesting data, you can increase the number of moments it deems worthy of storing.
To achieve this, you can:
-
Actively seek out new experiences.
-
Learn new skills.
-
Acquire new knowledge.
-
Spend quality time with loved ones.
By consistently engaging in new and meaningful activities, you can encourage the brain to create more lasting memories, ultimately making time feel more expansive and slowing down the perceived pace of life.
