**Why Does Time Go Faster As We Grow Older? — Transcript & Summary | SozAI** Source: https://sozai.app/transcript/time-goes-faster-as-we-grow-older/ Explore why time seems to speed up as we age, with theories on memory encoding, life proportion, and brain processing speed. ## Key Takeaways - Time perception changes with age due to memory encoding and brain processing speed. - The proportion of life lived affects how long a time period feels. - Neural complexity and signal travel distance in the brain impact mental processing speed. - Emotional states like boredom can also alter time perception. ## What the video covers - Time feels slower when we are young because new experiences take longer to encode in our memory. - Our perception of time is relative to the total time we have lived; a given period feels longer to a child than to an adult. - For example, two years represent a much larger portion of a five-year-old's life than a fifty-year-old's life. - Professor Adrian Bejan's theory suggests brain processing speed decreases as neural network complexity increases with age. - Younger brains process more mental images per unit time due to shorter electrochemical signal travel distances. - Older brains process fewer mental images because signals travel longer distances, making time seem to pass faster. - This effect is analogous to video frame rates: higher frames per second slow down perceived motion, lower frames speed it up. - Perception of time is also influenced by emotional states, such as boredom, which can make seconds drag. ## Chapters 1. 00:00 Introduction to Time Perception and Aging 2. 00:15 Why Does Time Seem to Speed Up? 3. 00:24 Memory Encoding and New Experiences 4. 00:35 Relative Time Perception Based on Life Lived 5. 01:00 Brain Processing Speed and Neural Complexity 6. 02:14 Analogy of Frames Per Second and Time Perception Answers ## Questions about this video Why does time seem to go faster as we grow older? Time seems to go faster because as we age, fewer new experiences are encoded, and our brain processes mental images more slowly due to increased neural complexity. How does the proportion of life lived affect time perception? A given time period feels longer to a child because it represents a larger percentage of their total life compared to an adult, making time seem to pass more slowly when young. What role does brain processing speed play in how we perceive time? Younger brains process more mental images per second due to shorter signal travel distances, making time feel slower, whereas older brains process fewer images, making time feel faster. ## Full Transcript — Download SRT & Markdown 00:04 Speaker A Remember the time when summer holidays felt really, really long? But the older you got, the faster the days disappeared until months and years went by without you realizing it. 00:15 Speaker A So why does time go faster as we grow older? Several explanations have been put forward to explain this phenomenon. 00:24 Speaker A The simplest of these is that it takes longer to encode new experiences than familiar experiences, and when you’re young, all experiences are new, so time seems to go slower. 00:35 Speaker A It could also be because our perception of time is relative to the time we have lived so far. 00:41 Speaker A Say, for example, if you are a five-year-old kid, then the past two years of your life represent 40% of all the life you’ve lived and can recall. But when you are a 50-year-old adult, then the past two years represent only 4% of all your recallable life. So, for a kid, two years 01:00 Speaker A might seem to last forever, but for an adult, those two years might not even seem long at all. 01:06 Speaker A Another theory proposed by Professor Adrian Bejan is that our brain’s processing speed decreases as the complexity of its neural network increases as we get older. When you’re young, the electrochemical signals in your brain need to travel shorter distances, 01:23 Speaker A which means you get to process more mental images per unit of time. But when you’re older, the signals have to travel longer distances, and so a lesser number of mental images are processed. 01:34 Speaker A Just as a higher number of frames per second gives you slow-motion video on a camera, life seems to go slowly when you’re young, and just as a lower number of frames per 01:49 Speaker A second gives you a fast-motion video, life seems to hurry by when you’re older. 02:06 Speaker A It isn’t just age that alters our perception of time. Every single one of us has felt the seconds drag by when we’re bored, but things seem to move in slow motion when we’re in Topics: time perception aging brain processing speed memory encoding psychology Adrian Bejan neural networks time relativity mental images perception of time Study this video - [Flashcards from this video](https://sozai.app/tools/ai-flashcard-generator/?from=transcript&id=73804) - [Quiz on this video](https://sozai.app/tools/quiz-generator/?from=transcript&id=73804) Free, made by AI from this transcript.
