I find the idea of turning me into a fertilizer quite disturbing and silly. What's the point of living for like 80 years and taking care of this body just to be turned into a fertilizer then fed to a tree which will be cut in a week or two. I would rather be burred instead or launched into space in some kind of a anti-decomposing time capsule, that would be interesting, being resurrected by Aliens after billion of years of dying is more interesting for me. Even in burying you get to at least leave a part of you in life. Anyway, I would probably donate my internal organs, skin and retinas the rest will be burred, I don't want to be turned into a medical school students playground.
