Everyone on my dad's side had kids late. I was 36 when my kid was born, my father was 36 when I was born, my grandfather was 42 when my father was born (and we are talking all first children here). My grandfather was a "change of life" baby (which means, no, you haven't gone through menopause - you're pregnant), so his parents were probably in their forties when he was born, although he wasn't their youngest. He grew up in a sod house and took part in the Oklahomah Land Rush, aka Land Grab. Two of my great grandfathers fought as teenagers in the Civil War.
I tried to read The Sound and the Fury on my own in college. It made absolutely no sense, probably because there were three characters named Quentin, and one was a girl. I didn't get that there was more one Quentin until I read it with a study guide, at which point it made some sense. One of my few forays into literature written before 1980. After that, I usually have at least a passing familiarity.
