Have you ever thought about the question that when you go somewhere, the return journey seems to be very short and takes very little time? why? This is because we do not know the exact length of the mileage is only estimated by some other clues, when we go to a strange place, the journey seems to be longer than the round trip.Because what we saw at that time was a series of new things, but on the return trip, we only need to identify some road signs instead of forming new memories
the brain feels that time shortens and space becomes smaller.
External stimuli affect our perception of time
