Watch out for those pesky olives!

Next time you're wandering down the supermarket aisle, or perusing the local deli shelves, keep an eye on the sell-by date of the olives. According to new research in Greece, only those packed in vacuum pouches could justify a claim to a shelf-life of almost two years - olives packed in air were only good for nine months. They won't kill you or anything...just won't taste as good.
