Thanks! I have a lot of arguments about wasting good food. At least now I have something that helps the discussion. And although the article states not to use meds past their expiration, my doctors/dentists often tell me to go ahead and use them. I always tell them what the medication is and the expiration date. I also store them "properly." Drug life/strength does vary, so ask your doctor of course. (I've heard some--very rare--can become toxic.)
