The article that I am about to share originally appeared on pages 149-151 of the March 2004 Real Simple Magazine. If you don’t read Real Simple, you’re missing out. It’s one of my absolute favorites! Lots of tangents just like WickedKate, but all to help you simplify your life! AWESOME! They even have their own website (who doesn’t now-a-days?!). In fairness, I did search to see if this would be available on their site, but couldn’t find it! It’s the periodic table related to the shelf-lives of everyday products. When should you get rid of ketchup? What about blush or bleach? Check it! It’s a great resource!
