Use a Coolbox Instead of a Fridge

If you live alone and have a freezer, you can use it to freeze cold cells for a coolbox, so that you don't need to use electricity running a fridge as well. My daily routine includes changing my cold cells when I get up, and when I go to bed. I also put anything that I'm defrosting into the coolbox in place of a cold cell, and I always freeze my milk when I first buy it, then leave it in the coolbox, using it gradually as it defrosts. The only items that have gone off are ones that would have done so if I'd had them in the fridge - some soft herb cheese and some mozzarella, both well past their use by date. My coolbox is one of the polystyrene containers that are used for frozen food or vaccines, so it didn't cost me anything.
