Yeah, this! I think you and I are pretty close to the same age. When the Simpsons started in late 1989, Bart was a 10 year old 4th grader. I identified with that, even though I was a whole year older! Homer, the dad, seemed impossibly old. I think he was 34. I am way older than Homer now. And that feels weird.
Though I haven’t really watched the show since the early 2000s. There’s probably more episodes that I’ve never seen than episodes I saw and adored.
