yeah that is going to be a nope from me. I find it in poor taste and I kind of consider a dead body to be someone akin to an empty container. A container that deserves respect and due consideration but no matter what happens it is now empty for good.
I would much prefer to have anything of worth organ wise harversted and used for transplants etc. and then the rest of me either cremated or buried. I prefer the though of cremation. I also don't like the idea of wasting money on something like my own funeral. Cheapest avenue possible. Maybe I'm wierd like that but it is just the way I am.
