I'm going to go with cremation. I'd hate for my corpse to take up land, and if it's preserved in a casket six feet under ground it'll be hundreds of years before I'll leach into the soil to provide any nutrients. Plus it may take up valuable land, and I'd hate for people to be bitching decades from now about how a building project might unearth me. I also personally disagree with organ donation, because who the hell knows who might get my organs. I'm picky about the people I associate with on a social level, I know I'd like to pick who gets my organs. Yes, I'm a selfish bastard, but I don't like being generous so I can feel self-righteous. I'd rather just be burned down, and dumped out in a certain special place. And I know my brother would be more than willing to do this. That, or I've also thought of a pine coffin, they rot relatively quickly, and at least your body will provide nutrients for the soil. This whole grand coffin thing is ridiculous.
