I got a lot of Craigslist tools that are from the 80s and 90s.
I have a desk from circa 1995 that I rescued from a hoarder relative. (They wanted it gone, I obliged.)
I have an old oak dining set that looks to be about 30 years old. Another secondhand find.
I know I have a few books that meet those criteria. I got rid of the ones I wouldn't use, but I have a few older cookbooks I love.
I have a few older physical DVDs and video games. I still occasionally watch the DVDs, the video games I emulate but I'm not ready to let go of the physical copies.
I have a small box of sentimental items that are older. Stuff like jewelry or old letters.
Other than that, most of my possessions are newer. A lot of my older stuff got lost due to having to leave bad situations and leaving behind who knows how much stuff.
