I don't want people to fuss about with a funeral or cremation for me really. I'll be dead and gone so I wouldn't care either way what the living do with my corpse. As for my files, documents etc, same goes there. Keep or delete them as they wish. Anything of value I'd like to go to nice family members who need the money or want for sentimental value.

On the other hand, I kinda like the idea of my remains being turned into an Aura Diamond and keps as a family heirloom. Perhaps every member of the family it's passed down to could have their remains turned into a diamond and added to it over the generations. Get a bit of family mythology going on there
