I'd suspect that was a wish expressed before death...
I've often said that I'd prefer not to have a big "funeral" service should I die (after my last visit to the hospital, I'm really beginning to think I'm invincible...
)
My preference would be for something small and quiet. Family and close friends can do as they choose, as they see best fit, however I don't want anyone doting over me in death (they don't do it now anyways and if there's gonna be any doting, I want to be there to experience it!)
I don't have it finalized (or even started really) but I've been seriously considering making arrangements for my body to be given over to a local medical school for study of my congenital defects... I'm at least "somewhat" unique when it comes to heart defects and I'd like to know that as much information as possible can be learned from me and my experiences to help other "kids" down the line...
It's another issue the family doesn't care to discuss much along with DNR's and living wills.
I do have some "knowledge" of how body donation works and I know that generally, when one dies who's body is to be donated for medical science/teaching, there is generally a memorial service held within a few days of the death (as is customary for most religions) and then the body is turned over the to organization who is sponsoring the medical use as per pre-arranged agreement. When they are done, the body may either be returned to the family for internment, or creamated either by the family or by the medical organization....
I've also "been lead to believe" that these arrangments often include benefit packages which help defray the usual costs associated with a death, funeral arrangements, burial plots, other expenses are taken care of, at least in part, by the agency that is going to be given the body for study.
What I know is based on "second hand" knowledge, mostly anectdotes from people who've had direct involvement with such arrangements.
Last year a local political figure died rather unexpectedly and there was only a small memorial service at the time of his death. The reason, in part, was because his body went to a medical school before internment. I don't know any other details beyond that. I assume he had a private burial or something afterwards, he had a family, but I don't know any specifics or even if it happened.
By the way, on a side note, my grandfather is due to be interred this Saturday. He passed away from complications related to CHF, kidney failure, and a broken leg suffered last summer. They would have done the internment after his funeral, but the cemetary grounds were too frozen.
Sometimes there are delays or extenuating circumstances, usually that information is kept within the family.
