I want my organs to be harvested and used for transplantation. If that won't work, I want to become a cadaver in a teaching college. If they don't want that then I want to be made into a live articulated skeleton. If they still don't want to do that, then disarticulate me and use the bones as learning parts. If the remains are totally unwanted, then burn the body and sprinkle the ashes in about a dozen designated spots in my will.
Like Duncan, I'd like my corpse to be used as much as possible to help, either thru organ donation, autopsy, education, etc. Then it would be cool if the leftovers were put up high outside somewhere in the wild, to feed the birds, like some Native groups used to do. Then burn the bones and sprinkle my ashes in the Pacific Ocean, just offshore of Tsusiat Falls.
I'd like to be buried as l want a tombstone, and have "Hey asshole stop standing on my grave" written on it.
