Another hunch that I have is that as you get older you tend to have less unique experiences. I believe our brains compress the information and an entire day that was much like the previous day can just feel like it sped by quickly. Alternatively, if you go on vacation or change your routine then time will slow down as you process a lot of new information.

Exactly. Often on vacation something I did in the morning will feel like a week ago.

> Another hunch that I have is that as you get older you tend to have less unique experiences I have read that explanation several times on different websites, but I don't agree. Had a lot of new and unique things happening to me in the past decade (kids, moving, new job, new country,...). Times still flew. I have talked to friends about this and they have noticed the same thing.

I don't buy the "novelty" thing, either. Between high school and an evening job, about three of those years were the most regimented of my life, and high school definitely wasn't providing enough novelty, in any way, to make up for it. Yet those years felt extremely slow compared to now. I feel like I blink and a season's gone. Fall or Summer used to feel so long back then. And Winter, practically eternal. Now it's l…

Another way to look at it: by the time you graduate high school, you will have spent 1/4 of your life there. By the time you are 40, 10 years is 1/4 of your life. By the time you are 80, 20 years is 1/4 of your life.

The relative portions of your life get longer the longer you live.

What I've speculated is that perception of time is relative to how much you've experienced, i.e. how long you've been alive.

When you're a child, a week seems like a long time, because you haven't lived very many weeks. A year seems like an eternity, because relatively few have passed.

As more of these increasingly large time units get behind you, years, then decades... you have a firsthand understanding of what living their respective durations feels like.

It's like by living you're calibrating your ability to measure time properly, and then you die.

That's another way to look at it, sure, but it still doesn't seem to explain anything about why perception of time speeds up with age. That's true, but why does it matter?

I've thought about this phenomenon a good bit as I get older. My hypothesis is that the older you get periods of time take up smaller and smaller fractions of your life span, and therefore seem to pass more quickly.

When you are 10 years old a year is a large fraction of the total time you have been alive so it feels much longer than when you are 60 and that same year is only 1/60 of your life.

edit: reading further down I see I'm not the only one who had this same idea :)

There is a simpler layman's explanation for this one. As you get older every second of your life starts being a smaller percentage of your overall experience. When you a 2 years old, 1 hour is 1/17520 of your life. When you are 50 years old, 1 hour is 1/438000 of your life.

I wonder what Taleb would say about this calculation.

This is my impression as well. Old people who have settled in a routine can tell what year and month it is, but probably have a harder time telling the day or weekday. For them, all days are weekends. You don't even need to be old to feel this. I've had vacations where I mostly played JRPGs, and those vacations certainly felt considerably shorter.

JRPGs, as well as the Civ games, are time compressors. You blink and 5 hours have passed.

Commuting / driving.

I have long believed the same. I also experience this when taking a long drive to a new destination - it seems to take longer to get there than it does to return home.
