Hunger.

Technically, what is hunger? When you say, "I am hungry," what are you really saying? Does it mean that your name is "Hungry" as in, "Hi, I'm Hungry, nice to meet you!" Or is hunger an emotion like "I am happy (hungry)?" This concept confuses me deeply, for I am hungry, and I do not know if I am expressing myself correctly. So, for now, I sense that hunger resides in the pit of my stomach.
