I used to think that age equated to percentage of life lived, thus I thought that most people live to close around 100.
But it also made me think that people only get old when they’re like 80.
I mean like actually “old”. The “old” adults were referring to. At that age I considered those 14/15 year old 9th graders old, just a bit different “old”.
I remember my grandfather’s 50th birthday party and all the balloons and such saying “over the hill”, and I took that to mean that 50 was when you turn old. Had no idea how long most people lived, but I probably would have guessed somewhere in their 60s (fairly accurate for the time).
