As individuals age, many experience a subjective acceleration of time, a phenomenon that can be particularly acute during significant life events such as expecting a child. This perception of time speeding up, and the desire to slow it down to savor experiences, is a common concern that prompts exploration into both the psychological and philosophical underpinnings of our temporal perception.
Time can be understood in two ways: prospective time, how it feels as it is happening, and retrospective time, how it is remembered. The feeling that time is slipping away can be influenced by a lack of novelty, as childhood, a period rich with new experiences, often feels longer in retrospect compared to adulthood, which is characterized by routines and habits. Neuroscientist David Eagleman's work suggests that novelty can expand the perception of time; introducing a new image into a series of repeated ones makes the new image appear to last longer. This is because the brain registers more details when encountering something unfamiliar.
Extreme emotions and dangerous situations can also alter time perception. Experiments involving free falls have shown participants overestimating the duration of their descent. This phenomenon is thought to be linked to the amygdala's activation, which signals the brain to pay closer attention and store more details, creating a sensation of time stretching. This is also observed in individuals who have experienced near-death events, such as mountain climbing falls or race car crashes, where time seemed to slow down considerably.
While adrenaline-fueled experiences like skydiving can offer a potent, albeit temporary, way to perceive time dilation, the author questions the value of obsessively seeking activities that maximize this effect, suggesting it could detract from the quality of life itself. Conversely, a state of "time urgency," characterized by anxiety, burnout, and multitasking, can make time feel even faster due to a reduced capacity for attention and memory formation. The importance of cherishing moments, even those spent with loved ones or engrossed in hobbies, where time may seem to fly by unnoticed, is also highlighted as a valuable aspect of a well-lived life.
Ancient philosophies offer perspectives on confronting the passage of time. Stoicism's concept of memento mori, or remembering death, and Buddhism's Five Remembrances, which emphasize the inevitability of aging and change, encourage a focus on the present. The impending arrival of a child, for instance, can powerfully bring these realities into sharp focus.
Beyond seeking intense experiences, alternative approaches to perceiving time more fully involve integrating mindfulness into everyday routines. Vietnamese Thiền Buddhist monk Thích Nhất Hạnh advocated for being present during mundane activities, such as washing dishes, rather than being lost in thoughts of the future. He suggested focusing on the sensory experience of the task at hand, thus reclaiming the time spent on it. This practice can lead to a more spacious way of living within the time available.
Introducing intentional periods of boredom can also expand the perception of time. Chris Bailey, a productivity expert, experimented with a "month of boredom," dedicating an hour each day to dull activities. He found that these gaps in routine could foster creative mind-wandering and a slower sense of time. While not always feasible to dedicate extended periods to such activities, incorporating "micro-moments" of boredom and paying closer attention to routine tasks can increase awareness of how time is spent and potentially make it feel more expansive.
The historical context of timekeeping, as explored by historian Daniel Boorstin, underscores that time is a human construct, a "landscape of experience." The author also touches upon the idea of "skill nostalgia," a yearning for hands-on activities that naturally consumed more time, suggesting a potential, though not fully romanticized, benefit in engaging with tasks that require sustained manual effort.
