Perhaps this isn't an age thing; I've been leaving unidentified white stuff to mold in the refrigerator since I has my first apartment. But since memory is often the first thing to go, wouldn't it be nice if you didn't have to lift the lid from that container of green goo to find out if it's still edible? Enter the DaysAgo Refrigerator Timer.

Simply stick the button-sized timer on newly-opened food and start the countdown. They come 2 to a pack, so this really cut down on the science projects growing in your fridge.
