I don't really see how people get any positive feelings from such a funeral.
When my father died, my brother and I both went to the mortuary before the funeral and insisted on seeing the body. (Open caskets are not a Jewish custom.)
The morticians were extremely reluctant -- there had been an autopsy, and he was cut open and etc., and they hadn't prepared the body for viewing, yadda yadda yadda -- but they eventually gave in.
I can't speak for my brother, but for me there was a definite, and strong, release of emotional tension associated with seeing the body. I wouldn't call it "positive," exactly -- I can't imagine a positive experience at my father's funeral -- but I'm glad I did it.
Of course, none of that has anything to do with cryonics -- we would have done exactly the same thing, with (I suspect) the same effect, had his brain been scooped out.
I'm not sure the effect would have been the same had his body been in a "cryocasket." Maybe; maybe not.
Not that that's a reason for him not to do it, either way.
Simultaneously signing up for organ donation and cryonics versus only cryonics. Does having less organs decrease the likelihood of cryonics (including revival) working? Is it a good idea to have only your head frozen anyway, to save on electricity and storage? Do the benefits of organ donation outweigh any costs it could possibly incur, since organ donation is known to work?
Discuss.
I'm an organ donor because signing up was quick and easy. I'm not signing up for cryonics, because I anticipate that my family and close friends will have a harder time overcoming their grief if my body is not actually present at the funeral.
