I know I've had food items like spices too long if they are in cans or bottles labelled in ounces. It's quite some time since we went metric, or since I lived in the US. I've moved with spices and kept using them, but I make a conscious effort to use up the older ones. Often using twice as much as prescribed renders old spice effective in a recipe.
I have furniture from my mother's house and that which I had when I was living between two houses in different cities, and I need to get rid of some of it. Inertia, inertia! This thread has been a wake-up call, whether I'll act on it is a separate question. One thought, if you're hiring a removalist, the cost may be the same whether you fill or half fill the truck or container, so if in doubt taking stuff with you and deciding to junk it later may not cost you more.
