I am often wondering about how addiction "feels". I don't consider myself being addicted to anything, and always wonder how an addiction actually manifests itself. Is it a pain? Is it comparable to being extremely hungry or thirsty?
Slightly related: a few years ago, I overheard a conversation between a fairly large woman and a child. The child said that it was hungry. The woman said: "Oh yes, that hurts". That struck me as odd, because even after eating nothing for 1-2 days, I never actually felt pain when I was hungry. It was surprising to me that some people seem to do, and it would have certainly explained why the woman was so heavy: I, too, would of course eat much more if being hungry was painful.
