OK. This one is actually a two-part test. If you know that this is paper, then you are not necessarily old. I can’t rule out that you are clever or that you saw this in a museum somewhere.
However, if you know that this is green bar paper and that it went through a dot matrix printer and that separating it into individual sheets was called “bursting,” then you are old. Sorry, but that is just the way it is.
Oh, and if you came up with this on your own, you are even older:
