Basically my whole family have signed our bodies over to the local medical school. They make all the arrangements and pay for everything as soon as they're notified upon death. They'll normally give you the ashes upon cremation after a year or so, but personally I've given them permission to completely skeletonize me and keep the skeleton indefinitely.
This helps society by helping student doctors learn, and it removes all funeral hassles and expenses. We can still do more low-key memorial ceremonies without needing a body. I realize this path doesn't work for everybody, especially those with certain religious beliefs, but we all just love the idea.
And for folks that do want to bury the body, it can be done way cheaper than the funeral industrial complex would have you believe. Our church keeps a simple coffin on hand that the family can use at cost. And we have folks who will prepare the body and bring it to the church. The only part we don't usually do is dig the grave. Cemeteries usually include that in the cost of the plot.
This is what both my parents and myself did. When my mum was diagnosed with Stage 4 melanoma, it was one less thing to worry about arranging and trying to find money for.
She went from diagnosis to death in two months so things were a bit disorienting and just getting a RESPECT form (aka DNR) completed was such a struggle as everyone I spoke to had no record of my previous conversation with the last person I spoke to.
When mum was admitted to the hospice, despite explaining the arrangements we’d made and showing them the paperwork, it was only by chance that one evening I happened to overhear a nurse mention that mum had ascites, which is one of the few things that disqualified her from being able to donate her body. I googled it and realised we would need to arrange and pay for her body to be collected, stored and cremated.
She died the next morning and luckily I was able to get that sorted about 2 hours earlier. I suppose the point I’m trying to make is that if you go through the process of arranging to donate your body to a teaching hospital (which you must do yourself ahead of time) don’t assume it’s on medical records or that anyone will advise you that the body isn’t suitable for donation for any reason. Like all NHS-related things in the UK, the systems are breaking or broken and so are the poor staff, so you need to advocate for whoever needs it and never assume what you said one day will be passed on to the next shift.
