Time management significant and perspectives

Pretty old guy (86) here. Something I have noticed about my perception of time is how fast it seems to go nowadays, and how it has been speeding up for years. I graduated from eighth grade in 1948. At that time not everyone went to high school, at least not every farm boy in South Dakota. At that time also, four years was roughly one-third of my lifetime to that point. So, after having spent almost two-thirds of my lifetime in school, the thought of almost another third of a lifetime doing something I pretty much hated was overwhelming. I begged my parents to allow me not to go, but they insisted,

Nowadays, four years is a much smaller percentage of my lifetime, and as a result, I think, four years seems to go much faster. So, although, in reality, clocks have moved at the same speed over my lifetime, my perception of that reality (that clock speed) has changed. And I think that perception relates to what percentage of a lifetime a particular amount of time is. For me, years back, weeks used to take a long time (Is it Friday yet?). Now they pass very quickly (Is it Friday already? Where did the week go?)
