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”.
When I was in grade school in the 60s, we had a math problem… “how old will you be in the year 2000?” I calculated 42 and thought “OMG, I’ll be nearly dead by then”…
