Dear Economist,
I have a question for you. You have a piece of bread and you are full enough to give it to someone else. In front of you, 10 guys are waiting for your charity. You can say only one sentence to them.
But with only this one sentence, you need to find out who is the most hungry guy. What are you going to say?
