I move a lot. I go through my things and keep seeing old "friends" I never use but can't part with.
My mum bought me a chess set in Mexico about 60 years ago. I still have a knight from that set.
My GF back in high school bought me a ring, 10k gold. Still got it.
Tools: That's where I can kick anyone's butt. I got tools from the 50s. I have the electric drill I used in wood shop in high school, still works, still use it.
Even clothes, got shirts from the 70s, still usable.
And this isn't stuff stored in my attic, I have no attic, this is what I've been carrying around since I got to traveling back in 1980.
God, the things I've lost along the way. You just never know what will last and what will disappear.
