I considered donating my body to my nearest University Hospital, but frankly the thought of my dead cold body being poked, prodded, cut open everywhere, maybe limbs cut off etc... not sure I want to leave whoever cares about me that idea or image of my remains.
I'm already signed up as an organ donor, I think that's as far as I can go when it comes to donating (parts of) myself to someone else or science. I'd like my loved ones to have a plot they can visit where they know my body, or remains thereof actually are, however stupid that may sound to others.
