The way in which the passage of time is perceived differs for each individual who experiences it, such as colors for example;
to exemplify, as children time seems eternal, "long-winded", since we are conditioned by amazement, since at that tender age everything is considered brand new the brain is hyper-stimulated, ergo, it has a lot to work on and the years that have passed we perceive them as "saturated," or, in the most positive sense of the term, "intense",
but when we get older or lose interest in life, everything seems "already seen", everything is monotonous or, simply, we have an apathy for the objects and tasks that life offers us that makes everything boring, therefore the brain is not stimulated at all as it once was and therefore time escapes because we have not filled it;
Then there is the lockdown to consider, which has certainly corroborated/fueled certain processes such as boredom, depression and monotony.
Furthermore, there are studies that attest to the decrease in eye movements when viewing new images in the elderly, compared to those in children, therefore, the fewer images stored during the collection of information we have on an object, the less vivid the associated memory will be to that object, as a result time will seem faster.
(eye movements are called "saccadic movements" because they take their name from the "saccade" which is the snapping movement of the eye; while awake we perform about 150,000 of them in a day).
