What is this date, you ask? An important date in international political history? The birthday of someone famous? The launch date of some groundbreaking Apple product? No. It was the expiration date of some lemon juice concentrate that we just threw out tonight (after, I must admit, my wife used it the other day in a recipe). We moved into our house in September of 1997, so it's highly likely that this particular bottle actually came with us during the move. So what's the oldest food item you've ever thrown out?
