Time is relative to age. When you are young, time takes longer. Five years is a long time from 15-20 years of age. However, it is but one year for the 30-35 year old.
When you change surroundings, such as to live in another country for a few months, it will feel much longer than it actually is. Time – our perception of it - is a function of age, surely, but more centrally, of newness.
New things require processing. For survival, the objective is to learn, and thus to put as much potentially ‘new’ information as possible into unconscious processing, freeing up brainpower for other things.
And so it [the perception of time] is also dependent on knowledge and experience. The more knowledge you have, the less things are new to you. And this is what speeds up time. It takes you less time to sift through the incoming info [enabling an automatic response instead].
Furthermore, it is then apparent that the more you know, the faster ‘time’ seems to fly by. As we enter the future, and we know more every day, and we are sharing information in greater amounts everyday, it seems logical that eventually, we will know ‘everything’ and time will speed up to the point of non-movement.
