My first gray hair was an ear hair. I won’t have to worry about the hair on my head going gray, it’s gonna fall out long before that.
This one doesn’t count if he’s one of your old classmates. Half the pharmacists and optometrists in my home town are old classmates of mine or within ±2 years, apparently my generation got some sort of “healthcare virus”. Bunch of doctors and nurses too, but those managed to mostly end up out of town.
When you walk past your old high school and wonder who left the 7th-graders there… and then you realize that, given that said HS now has only 11th and 12th (thanks to the latest educational reform) those boys are 16 at the youngest. I would’a sworn my male classmates were all taller than that by the time we turned 15!
OMG, that happens to a bunch of us at work all the time. We sit outside during our lunch break…somebody should (or maybe shouldn’t) videotape us trying to get back up! And all of us grunt too!
When you go to the doctor and the nurse who is taking your information, when asking about your family, asks if your parents are still alive (instead of just asking how old they are). And you answer, “only one of them.” 
When many of the people you work with weren’t even born when you learned to program.
I took a class on transistors 40 years ago - just 20 years after they had been invented.
When your kids comment on how young everyone looks.
When you can cash in your 401K money without penalty.
When people on this very message board think they are computer pioneers from having an old IBM PC as their first machine - or even a C64.
When the parents of the students who go to the school across the street (and some teachers) look too young to look at.
When the receptionist at the quite large medical center I go to knows me by name, without me having to tell her. Several receptionists, in fact.

Overall my biggest shock was being told by a young coworker (young being mid 20s) that we couldn’t be friends because I was the same age as her mother.
I think my mouth dropped open ten feet and stayed there for a bit :eek:
You go to a baby shower and identify more with the grandmother-to-be then the mom-to-be.
Yesterday at work, I hung up a new panoramic, large format photo of the mountain range visible from our office, taken from about a mile further back.
As I was hanging it, I was surprised to see what appeared to be a GIANT FREAKING WIND TURBINE on one of the slopes of Grouse, and sincerely believed that it was either photoshopped in as a wheeze, or some bit of schmutz on the on the photo that exactly resembled an improbably huge wind turbine in the same way that grilled cheese sandwiches sometimes resemble Our Patient Lady of Gruyere. Turns out that it’s actually there, and that all the young folks in my office have no trouble seeing it with their naked eyes. That makes me feel old.
Worse, just now when I was doing a GIS for a photo that gives the impression of how vastly, hugely, mind- bogglingly big it is - the best example I could find turned out to be one taken from the living-room window of an old friend from my youth. Said friend is also the most recent of my friends added to a growing list of those whose memorial services I’ve attended. That makes me feel older. 
…you say to yourself, “I should probably bring this up next time I see my doctor.” But:
–You can’t remember the dude’s name
–You forget to to look it up when you have a spare minute
–You only remember the original issue when it happens again
–You still can’t remember the dude’s name
–etc.
Also, you consider fewer and fewer of your minutes as “spare”
You realize that in a couple of months there’ll be no retirement facility that could exclude you due to age.
You keep one of those “granny grabbers” on each floor of the house.
An “all-nighter” means you made it through the night without having to wake up to go pee.
You wonder if any new pain you wake up with is going to be with you permanently.
Those are good ones! i have a couple of pains I’ve been living with so long they’re like old friends, but when I get a new mystery ailment, I think, “oh oh, is this IT, is this the beginning of the end”?..Today on the oldies station on the radio, not only was there an advertisement for a senior citizens apartment building that was recruiting new residents, but I learned I was so old, I could have moved in there five freakin’ years ago! (I better write down the name of it so I don’t forget…)
Yes. This is one aspect of getting older that I’m most aware of.
That is what it originally was with records, before the advent of LPs. If you bought a long work, like a Beethoven symphony, it often came as a binder full of several thick 78rpm discs, each in its own inner sleeve with the window in the center allowing you to see the label.
The album as a cohesive creative format for popular and jazz music didn’t really exist at that time; by the time musicians were thinking more in terms of albums, the word was already an anachronism. But it stuck, in much the same way as some people still talk about dialing phones.
You read and hear about people being nostalgic for stuff that happened when they were kids … and you were already an adult at the time.
(I previously posted this one in the “90s Nostalgia” thread.)
OK, you made me choke on a Cheeto with that one! So true, so true, so true!
You catch yourself walking around with your glasses on top of your forehead.
Although I do have a slight advantage in that mine are prescription glasses for nearsightedness, and I have to get them out of the way when reading or working at the computer. This makes them a bit harder to lose or forget.
My grandmother told me it’s when your grandchild becomes a grandparent themselves. We have several five generation pictures with her.
I had to explain to my youngest daughter that at one time everybody listened to records, not just DJ’s who haven’t made the transition to digital yet.
I also had to explain to her what a pager was.
I had to explain to my oldest daughter who Don Henley is. Not recently either…I told her this years ago.
I still remember being excited about watching B.J. And The Bear because it not only had trucks and a trucker, but his sidekick was a chimp.
