Do you know what a transformer is? You can often see them near power lines, reducing the voltage down to 220v or 110v before it goes into buildings. We've all got smaller ones in our houses, reducing voltage down to 12v or 9v, for charging mobile phones or playing small portable electrical devices. Anyway, I just overheard one of our Liberian staff saying that his people were so hungry in the war that they used to drink the oil from inside transformers to take away the hunger, and use it for cooking whatever they could scrape together. How terribly sad. Little things like this really shake me up now and then. Photo of a transformer. Olly
