Enders Game: my very very favorite sci-fi series ever. My cousin loved it so much, she named her first born son Ender.
And as for more natural means of after-death care, there's a growing movement of people wanting no embalming, no treatment, just being left for nature to reclaim, either by burial (that's actually good for the earth) or cremation. If you're at all interested, you should check out Caitlyn Doughty on YouTube. She's a funeral director in L.A. (I think), doing alternative care for the dead. She's entertaining and inspirational and educational. I want to be her.
