This topic was never something that was discussed at any school I attended. But it is something that I have thought about independently and come to the same conclusion. My life up to the age of 5 seems subjectively longer to me in memory than my life from age 17 to now (I'm 30). I have always felt that at ages 0-5, I had a much shorter total life experience to compare the passage of time to, so it feels longer. I suspect that certain experiences occurring at certain periods also have a bearing. I find that some experiences tend to signal the beginning or end of different stages of my life and in some way I'm not fully able to describe, this seems to have some effect on my perception of time as I look back. But for me, there's definitely something in this comparing any time period to how long you have lived so far.
