There is very good reason to be concerned. Kodak keeps it stored way down
deep underground when they are "aging" it, to keep it's exposure to
"cosmic" rays to a minimum. But it's just a matter of testing. It won't be
a problem with color obviously, but from fogging. So if you don't see fog
in a test roll, I would suspect the batch is good. It would be rather
consistent I suspect.
