There is no way that Nirvana is Oldies. I don’t even consider it retro! At least not until 2012. I would put it into the Oldies catagory in at least in the 2030s. It’ll be a “Classic” in the 2020s, and “Oldies” in 2030s. That’s just my opinion.
I tend to calculate the years when things happened by the year I started teaching school. I recently realized that was more years ago than my age at the time.
A guy I have been friends with since I was 14 retired last year.
A few things I remember that really make me feel old:
Our house was unusual because it had 2 phones. Not two phone lines, two phones, one in the basement and one in the kitchen.
My great aunt Edith had what would have been a rotary phone, but it didn’t have a dial on it. You picked it up and an operator said “Number Please.”
Color TV was a new concept when I was a kid.
My brother miraculously escaped serious injury in a car accident when his head hit the windshield. Almost no cars had seatbelts.
More recently, my first computer’s memory could be expanded to a whopping 48k. I couldn’t imagine how I would ever use that much space.
I will be 50 next year and I’m still trying to decide what to do when I grow up.
You do understand your duty to educate this boy and give him a proper cultural background, right? “Who’s Indiana Jones” indeed.
My reminders?
My nephews, whose diapers I personally changed on many occasions, are now old enough for ol’ Uncle Kilty to buy them both a beer. The older one is engaged to be married now.
College kids call me “sir”.
I’m the same age as my doctor.
Forgot to mention - in October I’ll reach the ripe old age of 33…
My friend had an old moment a while back. She was 31 at the time, shopping with her three young boys (oldest was 6) at Target. To decorate the music section, they’d suspended 45s from the ceiling. Her oldest looked up at her and said, “Mommy, what are those?”
I felt funny when I went back to my hometown a handful of years after graduating from high school and I no longer recognized the kids behind the counter at the grocery store and Dairy Queen. I felt old when I went back recently and not only did I not recognize them, I thought to myself how young they looked.
It feels strange when I think about how some high school classmates of mine have kids nearly as old as next year’s 10 year reunion (some older!) - and I have no plans to have any in the foreseeable future.
Time flies.
And just think, that was almost 10 years ago! So what are you now, ten years after “old”? 
Mine came when I realized that most of the kids I work with drive themselves to work, and they were born in 1988.
Oops, I forgot that detail, didn’t I? I was 34 at the time.
Time alone will tell. All you need to do is wait for it.
It also doesn’t help when people with your birthday graduated high school in 1983 and talk of “old.”
Or when you get a photo from your high schoolHomecoming Queen and go back to your yearbook.
