Okay, there’s one that make me feel kinda old. Remembering when boner pills were a new thing and be shilled during primetime television by a presidential candidate.
I feel old when I get up off the couch and can’t stand up straight and have to shuffle along hunched over because my back has gone out. Again. 
My cat is about 5 years old.
I once realized that it is about 50/50 as to whether I will bury her or she will bury me.

Waking up tired (fatigued).
Only last week did I seriously begin to feel old. I can’t get rid of Trump in my Facebook suggested pages. I tried blocking the pages, clicking off of them, reporting them, even “liking” liberal pages – even though I don’t want to see more liberal stuff in my feed, I just don’t want to see Trump’s face ever again! None of it is working and I am considering not using Facebook because of it. I don’t know what I did to deserve to be lumped in his demographic.
Previously everything else that happened was more like “haha, stuff I like happened a long time ago” but I seriously do not like this.
The phrase, “Wha…? What’s a… Stick Shift…?”
70-something women holding doors open for me … that’s just cold …

…he was the teacher.
After showering, not being able to reach down to dry my feet and ankles.
Discussing the topic of old movies with my daughter. When I think of old movies I think of movies that starred John Wayne or Elvis Presley. When she thinks of old movies it’s movies like Ghostbusters or Weekend at Bernie’s, the movies I grew up with.
(Apologies in advance)
Having to get up three or more times a night to pee.
Beauty and the Beast, which I admit I saw when I was in elementary school, came out closer to the Apollo 11 landing than today.
