You’re comparing two different scenarios. Let’s say you have two cups, one is made out of paper and the other is made of glass. They’re 6 feet off a concrete patio. Wind isn’t an issue.
Let them sit forever, and the paper one will disintegrate long before the glass does. Tip them over, and the glass one will shatter.
I didn’t mean “sitting in a garage not getting used”, I meant “getting used, but not getting in an unpredictable accident”
Accidents are an additional variable outside of what the original article is talking about
