I know what they mean.

I cleaned out my freezer this week and found an old chicken breast that had slipped to the bottom of the vegetable drawer. It must have been there for over six months.

It looked like it had dried up like leather, You could probably use it to repair an old pair of shoes. Its a generational thing, we used to have a cobblers in the high street where we used to have our leather shoes re-soled.

It didnt look good at all. You certainly would not want to eat it, though I noticed my pet cat tigger, looking at it, drooling, with an unsavoury look in her eyes.

If you cant keep a nice chicken breast in good order while it is frozen what chance a human body.
