It's inevitable, at some point in your adult life there is a moment or thing that makes you feel, well, old — and usually, it happens unexpectedly.
And a couple of months ago, Reddit user Halloween-365 was curious about just that when they asked: "What makes you feel old as s***?"
The thread went pretty viral with 13k comments, mainly from millennials and Gen X'ers who were reliving what makes them feel old. Here are some of the top and best comments:
1. "People who were born when I started college are starting college."
2. "Listening to Nirvana today is the same as listening to the Beatles in the '90s."
3. "Having to scroll and scroll and freaking scroll to find my birth year when completing an online form."
4. "People romanticizing the '90s aesthetic."
5. "One of the new soldiers in my unit was talking about how they learned about 9/11 in history class. Bitch, I was in class when that happened! F***, might as well join AARP now."
6. "I'm in my 30s, doing an apprenticeship for a new career, and there's a kid in my class who was born the year before I graduated high school."
7. "Doctors are younger than me now."
8. "Hearing songs that were popular when you were in middle school and high school playing in the supermarket."
9. "I'm an older first-time parent. Ran into someone I knew from high school when I went to pick my son up from daycare. She was there to pick up her grandson."
10. "Being the guy that owns the Gmail and Hotmail email addresses with just my first and last name together. All the other same named people have to add a number or something at the end to have their name."
11. "I was watching a makeup tutorial on YouTube, and the girl was using some butterfly clips to keep her hair away from her face, and she said, 'Girls used to wear these in the olden days.'"
12. "Not knowing any of the newer artists at festivals."
13. "Went to a museum in Seattle, and they had a video game section. A group of young teens are standing in front of a GameCube. One kid says to the other, 'I think this is the first Nintendo.' The other kid responds back, 'Isn’t it the first game system ever?' The first kid responds back, 'I don’t know. maybe?'"
14. "Went to a public library. They told me that they no longer use USBs/thumb drives."
15. "Going back to my uni and making Shrek jokes with students, then realizing that they were all born after the first Shrek movie came out. Their introduction to Shrek was as a meme, not as a character."
16. "I tried to pull something remotely similar to an all-nighter recently and got about three hours of sleep. I wanted to die."
17. "Last week, hearing on the radio that Carson Daly celebrated his bday, turned 50. I used to see him way back when on TRL. First dude that I ever saw wearing nail polish before. Just amazing how much time has gone by, and how he has progressed."
18. "That the '90s wasn't actually 10 years ago."
19. "I still use my AOL email account. I used to get made fun of for that. Like, 'AOL? How old are you?' Now, I don’t think many people under 30 even know what AOL is/was. No one says anything when I tell them my email address. I’m now too old to even be made fun of, I guess."
20. "I was listening to the radio, and I realized I didn’t like the new music on it…and, gradually, the realization and horror crept in."
21. "Kids don't know what a house phone is."

24. "My younger brother-in-law walked in the room a few months back while I was watching Alf, and he asked me if I was watching The Muppets."
25. "I recently went to the Smithsonian National Museum of American History in Washington DC, and there were numerous items from my childhood in there. Numerous items."
27. And lastly: "The fact that we're closer to 2050 than we are to 1995."
