Things stay preserved better frozen than generally believed. This is such a relief. Let's not worry about that bag of cranberries residing in the lower strata of our freezer, although every now and then we get quite a surprise because of a faulty memories and no database of deposits what so ever. Nothing too surprising then to discover moss spores surviving a couple of thousand years in a permafrost deep freeze. Some place TPP read about a lupine seed that had been frozen for 10,000 years or so in a tundra deep freeze. Now this makes those paleo-porkchops not so scary when you find out they've exceeded their freezer limits by a couple of years. Wonder if they will grow?
