So interesting, because I had the opposite response. Sure if I donate my body to "science" and it's critical in some sort of medical discovery that would be great, but reading the OP and seeing the author's fascination, learning, and engagement with the cadaver I thought, "Gosh, what a gift!"
I'd certainly be very happy knowing that my body brought such an experience to another individual, I certainly won't be using my body anymore at that point.
I wonder if, when signing up for donation, you can specify what kinds of "science" or interactions you prefer your body to be used for after dying.
