Nice perspective and analysis. I actually have been thinking about this for awhile and came to the following conclusion: The perception of time gets faster as you age simply because you are more aware of how long something is.

For example, the more knowledge you have of something, the better you understand it. The same goes for time, if you have experienced it for a longer period than others, you have a better way to measure that time in comparison to what you are doing in the present.

I was very busy with college and starting my career in my 20's, but it seemed to go on forever. Now that I am in my early 40's and working hard as ever with my career, I seem to be seeing time move by faster.

This is something that a young person may never understand until they live it through their 20's and 30's.
