I doubt it's exclusively to do with time as fraction of life. I suspect it's more to do with novelty: when you're young, much of what you see is new so you take it in and mull it over with some awareness. As you hit your working life, days can blur together as you engage in the same sort of tasks over and over. Later, as you reach mid career, most situations you encounter similarly become routine and you don't notice stuff which may have been remarkable a few years before. The effect is that you don't notice the weeks and months whipping by, since much of it is tuned out by your ever-growing filters.
Thinking more, I wonder if there aren't two effects at work: one is the fractional piece the presentation talks about: that's what makes being asked to wait five minutes seem intolerably cruel to a four year old. Then, the sense of time speeding up in adult life is caused by the growth of experience and dearth of novelty.
Explains why travel keeps you young and a change is as good as a vacation.
As someone with retrograde amnesia, I can confirm - this is exactly what it feels like. It's very interesting experiencing (essentially) the first few years of your life while being fully alert and forming memories.
I never seen any sources that the "increased speed" in our time perception is really due to "a year being a larger fraction of ones life" for example. Yet this site states it as if it's a proven fact. I'd love to see some sources if anyone has them.
Also, this doesn't intuitively work with a trackball unless you know to use the down arrow. Trackballs? Who uses trackballs? Well, they get across screen real estate a lot faster, IMHO.
