My Auto Zone Rewards card is from 2007, hard to think that the card is close to 20 years old now. Last time I used it, I used it to scrape glue off the side of a truck LOL!
Organ donor card. It's all registered online/electronically now, so not necessary at all, but it feels right still to keep it with me wherever I may get run over or mauled by geese so as to not let any organs go to waste.
