Question

From what I can tell and what thus far all people with whom Idiscussed this subject confirmed is that time appears to"accelerate" as we age.

Digging a little, most explanations I found basically reducedthis to two reasons:

• As we age physically, a time frame of constant length becomesever smaller in contrast to the time we spent living
• As we age socially, we are burdened with an increasing amountof responsibility and thus an increasing influx of informationwhich impairs our perception of the present

To be honest, neither sounds entirely convincing to mebecause:

• In my perception "local time" (short time frames that I don'teven bother to measure on the scale of my lifetime) is alsoaccelerating. Just as an example: When I wait for the bus, timegoes by reasonably fast as opposed to my childhood tortures ofhaving to wait an eternity for those five minutes to pass.
• Even after making a great effort to cut myself off from societyand consciously trying to focus on the moment, the perceived speedof time didn't really change. (Although I did have a great time:))

Which leads me to a simple question (and a few corollaries):

• Am I just in denial of two perfectly plausible and sufficientexplanations, or are there actual biological effects (e.g. changesin brain chemistry) in place, that cause (or at least significantlyinfluence) this?
• Is there a mechanism, that "stretches out" time for the youngbrain so that weight of an immense boredom forces it to benefitfrom its learning ability, while it "shrinks" time as the brain"matures" and must now act based on what it has learned, whichoften involves a lot of patience?
• If there is such a mechanism, are there any available means tocounter it? (not sure I'd really want to, but I'd like to knowwhether I could)
