This question has always sort of been in the back of my mind, but i think it has to do with a number of things.
MOstly just that when you're younger, you havent experienced as many seconds, or minutes, or days, so each one seems longer, because perception is
usually relativistic, and as you experience more hours, days, weeks, years, etc... they each take up a lower percentage of that which you've
experienced, so they "seem" shorter, thus time appears to move more quickly.
Another theory is that our perception of time is directly affeced by our cognitive activity. ie: if you're just sitting around staring at a wall time
will seem to move ridiculously slowly, becaue you dwell on the time, rather than your mind being occupied with thoughts pertaining to your activity,
whreas if you're reading or watching a movie, etc. your mind has more to think about and thus doens't dwell on the amount of time that is passing.
