Shite...haven't really thought about it.
Honestly I'm going to say balls to the more modest ideas presented in this thread and say I want something old-school. Being buried preferably, but maybe being cremated and having my ashes poured into a river would be a nice, symbolic way of moving on for both me and those there for me down the road.
Balls to the apparently agressive need for space six feet under the Earth (ignoring such a thing as burials so the world can greedily thunder on is a bit of a depressing thought actually), I'm the one that
died so I don't see why I can't pass on peacefully.
As for the organ donation route, sounds like a nice thing to do, why not? It's not like it's desecrating my entire body or anything, could help save a life
. Heck, maybe the people I donate my parts to will donate those parts and those that take them will donate those parts and so on so a part of me (aside from my outstanding legacy of fucking bitches and getting money) will always go on.
