Some of my coworkers were talking about using RSS to read blogs, which made some of the younger folks in our team ask what it is and why we keep using it.
Some still use iPods to avoid subscriptions and streaming services, my favorite was one of our sysadmins who showed me Gopher.
Yeah, I use a Jeep and a lawn mower that are both ~30 years old, but if it is the age of the technology and not the item, maybe fire or clothes... Wait, shelter has to be before those two.
