As drywall ages it loses properties?

We needed a few pieces of scrap drywall and someone gave us some. During the conversation to arrange pickup they mentioned they had the pieces for a good while and that "if you keep it too long .........." I'm not sure what the guy said but it sounded like over time it might lose some of it's properties such as strength, or other property.
What are your experiences with storage of drywall over time?

It's usually no longer flat if it wasn't stored laying down.

I've not noticed any change from just age and I've used plenty of scraps that have been laying around for years. It has to be stored where it won't get wet or be exposed to high humidity for any length of time.

Maybe the paper yellows a bit as well.

Moisture [humidity] can damage drywall but if it's straight and hasn't swelled any I would not be afraid to use it.
