Kokiri - I think it would be great to be a real life Kokiri, because you wouldn't have to grow up, and that means you don't have to worry about anything like Education, Work or any other stressful time taking things that life throws at you. You'd be able to do what you wanted all day and night, the only weird thing being that your parents would be the same age as you, along with their parents...etc. The only downside to all of this is that the Kokiri aren't meant to be able to leave Kokiri Forest (although the ending of Ocarina of Time says otherwise)...
