Matrix is a movie I will get around to seeing one of these days. I keep telling myself.
Thanks xkcd I guess now, I won’t.
For me it’s watching commercials for the latest teen shows, not thinking much of their young ingenue, it-girl stars, but thinking, “Hmm, their moms are hot though!”
That reminds me of the times when I see the kids getting on the school bus. I wonder why the bus drives off without some of the girls until I realize that those are the moms.
Well, you don’t have to wear your KISS platforms as slippers, you know. 
The other day I drove by a road that, 17 years ago, I drove an hour on just to see where it went to. I ended up going over a mountain and into another state and I thought it was a grand adventure. Now I’d never do something like that, instead worrying about the gas, the wear and tear on my car, etc. I must be old.

Seconded on having to scroll waaaaayy down when entering one’s birth year.QUOTE]
Thirded, though my birth year is ‘‘only’’ 1984.
As a friend the same age as me once said, '‘There are people born in the ‘90s now!’’
Also, my mind seems to be stuck in the year 2000, as I think of the ‘‘last decade’’ as the '90s and people born in 1970 are 30 years old.
Well, there’s one right there - I graduated from high school in 1984. 
Not just younger, but born some time after I graduated high school
For me, it happened when I was only 36. I’d started playing bass and singing in a cover band, with gigs playing in bars. I had quit drinking when I was 28, and hadn’t actually set foot in a bar since then. So I was on stage and looking out at the audience, and found myself wondering, “Holy crap, does this place even bother to check IDs?” It looked like a crowd of teenagers to me.
It gave me new appreciation for why all those “older” people kept calling me a “puppy” when I was 21 
People assuming that you have grandkids. This has happened twice to me in the last few months.
Constantly getting applications for AARP
1943 … ::::: sigh ::::
I spent a pleasant few moments mildly letching after three sweet young things in the next booth at the Subway, then overheard their conversation and realized I was older than all three of them added together. 
That happened to me for the first time over Christmas.
So while yes, I know that I am technically old enough to be a granny, it’s still a bit of shock to know I look old enough to be a granny.
When I read an online visual meme pointing out that if That 70’s Show were made today, using the same time gap the actual show had when it first aired, it would be called That 90’s Show and be set in 1991.
Oh, and that the baby on the cover of “Nevermind” was, as of a few years ago, in his early twenties.
I go to Taiwan on business, and deal with some people professionally who weren’t born when I was there as a college student 30 years ago…
Two recent examples:
-
Last weekend, I attended a gaming convention at Indiana University, where we played Pathfinder (a version of Dungeons & Dragons). The convention staff was going to be putting on a seminar during the Sunday morning “slot”, on how to be a better game-master. I noted to the other attendees that I’d be sleeping in on Sunday morning – I thought that the “GM 101” seminar was a great idea, but that I’d probably been GMing for longer than most of them had been alive. I said this jokingly, but, when we started comparing notes, I discovered that it was, in fact, true.
I started GMing / DMing D&D games in 1982, and none of them were older than 30. -
I was having a conversation at work with a co-worker, who’s in his mid 20s. I take guitar lessons, and he was asking me about what song I was currently working on. I told him it was a song by The Traveling Wilburys (“Heading for the Light”, to be precise):
“Who are they?”
“Sort of an accidental super-group from the late 1980s.”
“Who was in it?”
“Do you know who George Harrison was?”
“Not sure.”
“He was a Beatle.”
“Oh, OK.”
“How about Bob Dylan?”
“Nope.”
“Roy Orbison?”
“I think I’ve heard the name…”
“Tom Petty?”
“Nope.”
“Probably haven’t heard of Jeff Lynne, either, I imagine.”
“No idea who he is, sorry.”
^^^ God, that’s scary.
Realizing that when you were in your 20’s, you called in to work sick if you felt as lousy as you now do every day.
That reminds me of an item from a list that was going around the 'Net a few years ago titled, “Signs You’ve Grown Up”:
The phrase, “I’m never going to drink that much again!” turns into, “I just can’t drink like I used to.”
