Nevertheless he was a good fellow, generous by nature and capable of sharing his last crust with a friend; indeed he did literally share his last crust with me more than once. He was probably capable of work too, if he had been well fed for a few months. But two years of bread and margarine had lowered his standards hopelessly. He had lived on this filthy imitation of food till his whole mind and body were compounded of inferior stuff. It was malnutrition and not any native vice that had destroyed his manhood.
-George Orwell Down and Out in Paris and London
