Not only might it do so good, apparently it saves you most the cost of burial or cremation. Hope this is not something happening soon.

I agree with your hope, I hope the same thing
But one can never be too sure when that moment comes. I'm a non religious person so there is no hang ups for me on that front and I feel my old dead body might help in some one in their study to be a doctor/nurse or whatever. I feel I have something to give. Old for one thing, 40 plus years of smoking pot. A creative mind plus my mother had dementia in her later life. It was before Alzheimer's became a common talking about condition so its anyone guess if thats what it was. After her passing I mentioned to my brothers and sisters that I think she might have had Alzheimer's of which non of them had heard much of anything of. Anyways I was exposed to Agent Orange for 15 months of my life. I have no desire to take up a 3 ft by 6 ft section of this earth to house my old dead stinking carcass after I die so my instructions to family is that I be cremated with my ashes put in a hole with a sycamore tree planted in that hole, they choose the location. After all my spirit will need a place to call home and a big ass old sycamore tree would be a good place to rest.

Peace

that should be planned for: the medical school, whatever, that you choose may not want/need your body for whatever reason at the time of your death, so ensure that you have a back up plan in place to save your family stress.
