Eeveryone is saying "the hair is the first thing to deterate." we only know that fact from seeing humans and mammals die. Fairies could be completely differant who are we to question there life? Just beacuse we have never seen a fairy. My guess is that Fairies are very differant then us including the way that they die. I think that somebody somewhere has seen a fairy but doesnt want anyone to know. Think about it, if a human caught a fairy all we humans would do is test on it and end up killing it. I think that the world isnt ready to really see fairies yet, the reason why they havent reveled them seleves to us yet.
