Exaggeration

People use exaggerations to show how intensive or how great something is. From example some people will sometimes say "I am so hungry that I can eat a cow within a minute." or mabye "He is fast like a wind". From the above two examples, we all know that they are impossible. It is impossible for a human been to finish a cow within 60 seconds, Well, mabye they can if the cow is super small. Even the expression is not possible, people say that to show how hungry the person is. This is just an expression, there is no literally meaning. Another expressions talks about fast is even more impossible. How can a human be fast like a wind? The sentence is just trying to show how fast the person is. I heard people saying exaggerations pretty often. For example, I hear people say "I will tear you into pieces if you don't do that!" Well, of course they won't tear the other person into pieces, but the person will become very angry if the other person doesn't does certain thing. Sometimes I will say "I will die!". I won't die, but it just shows that I am very nervous.
