The premise is completely wrong. If you are young, you don't know what percentage of your life one year is.

More likely explanation is the compression of memories: if you experience things that are similar to things you have experienced before, they won't use up as much memory. Think about your daily commute to work: can you remember every single day you commuted? Or did all the commutes blur into one?

This makes sense; for instance when you are 10 years of age, a year represents 10% of your life, and seems like a very long time. However, when you are 50 years old, one year has reduced to only 2% of your life, and hence seems only one-fifth as long. Interesting hypothesis, and he makes it look very scientific with the formulae and all, but it's still a wild crazy guess that delivers no actual falsifiable prediction…

"A large factor of it would actually be that our brains don't store repetitive events very well." My theory, which is logically consistent with yours, is that as we get older we spend more of our cognitive cycles thinking in terms of abstractions rather than using our senses to process direct experience. This is partly because as we get older we tend to immediately place things we experience into categories and then…

You just described my theory exactly. Humans have to learn how to exist in the "zone" of mental abstraction... this is necessary for advanced cognition, but while we're doing it we don't really notice the passage of time.

I can't help but wonder if the hours I spent waiting for the last few minutes of boring class periods to end during my schooling might have actually been great training for "zoning" where the sped up passage of time is actually the goal.

I've often thought the same thing. It has me thinking cautiously about the sociological implication rapidly expending 'senior' demographic, growing life expectancy, and the rapid pace of world changing technologies. Is there a point where senior citizens can't keep up cognitively, despite the medical advances that may keep their bodies younger? And further, is there a point where their dominance as a percentage of society means we need to slow our adoption rate of consumer technologies to account for neurological barrier?

I also think about the people who want their brains crygenetically frozen after they die. Assuming they die old, with this cognitive scaffolding adapted to life today, I can only imagine the impact of 'waking up' into a world 100-300 years in the future, with such a drastically different world. That sounds psychologically crippling to me.

And finally, are there techniques I can take advantage of now, when I'm [comparatively] young, to keep my brain receptitve to new ideas, mental models, and raw sensory input? Meditation? Arts? Travel? Literature? All of the above, and if so, where do I find time for it all, while advancing my career?

As the cliche goes, if you don't find time for it now, you'll pay for it later.

off topic: why is equation rendering still broken on the web? http://everything2.com uses pre tags, wikipedia uses rendered png images. is this just another ie work around or have we really not implemented a standard yet. googled it myself http://en.wikipedia.org/wiki/MathML edit: thanks mbell! mathjax looks great project to get mathjax working on wikipedia ~> http://en.wikipedia.org/wiki/User:Nageh/mathJax breakdown…

Mathjax does not work great. It is slow, bothersome, and easily broken.

LaTeX and the web are in essence incommensurable.

Subjectively a good way is to remember how long summers felt when you were a kid. A summer felt like forever in the first couple of grades. Now think how long summers feel now, they just sort of fly by. It is kind of scary. Remember my grandma sometimes got confused what day or week it was and as a kid I could never understand that. How can you miss such a long period of time like a week and not notice, but now I sta…

To be fair summer vacation is shorter in most areas than it used to be due to an extended school year. The standard used to be 180 instructional days for kids, per year but it keeps creeping up there every year teachers renegotiate their contract for a raise.

My theory is different. Our brains work like film cameras, the faster the camera is rolling the slower time in the film seems to be going during playback. Because less time has passed since the last frame was captured. The slower the camera is rolling the faster the film seems to get when you play it back. Our perception of time is based on comparing what we last remember while we were conscious with where we are in…

Could you please email me? I was unable to find contact info on your web site. Thanks! :)

Well that's no good. I'm a ux/ui person. I must have failed. It's the mail icon (next to the twitter, skype, and kickstarter icons) in the sidebar on my website.

The fluff in Freeman's article (Journal of Irreproducible Results, I think) is the same cheerful fluff students were subjected to in the non-honors physics class at my high school in the 1980s, where the point of using physics predictively went out the window (leaving only untestable descriptive math, which isn't a waste of time, but could be applied to something testable), and with the same fundamental failure of simply not caring whether there might be an underlying mechanism related to the impression of remembered time versus the subjective speed of time currently.

A change in behavior can also have a huge impact on how fast current time is flowing. A simple hypothesis that the subjective rate of time passing is related to the intervals between encounters with the unfamiliar easily leads to a more fruitful set of thought experiments than Freeman's weak exercise. And potentially one that could be rephrased in biological terms.

I've noticed that when I take trips to elsewhere in the world, the more different the place, the more time dilates, both while I'm there and in memory afterwards. Doing only the familiar is the recipe to time slipping by, unmarked and unnoticed, like driving to work and realizing upon arrival that one has no memory of the trip.

So the question is: What should you do to extend your subjective time?

It is more than that. Summer felt as long as a year feels now, it is not just a couple of days of difference.
