I'm sure you've seen tons of those posts online saying, "If you recognize these things, you're officially old." As a Gen Zer, I honestly couldn't pick a floppy disk or an eight-track tape out of a lineup. But lately, I've been thinking about the opposite — the things that actually make me feel old because I don’t recognize them at all. There are trends, gadgets, apps, and random objects younger people use every day that leave me completely confused. It's a weird feeling realizing you're aging not by what you remember, but by what you no longer understand.
