Another idea is to leave your body for forensic scientists to dispose of. They'll leave you to rot for a while in a tree or stuffed in a dustbin in the woods, or be predated on by hedgehogs, then cut you up to see how to use the evidence in 'real' cases. They call the area 'The Body Shop.'
Historical precedent. My ancestors exposed bodies to avian and insect scavengers, and only buried or stored bones. Separated.
