I want something meaningful done with it. I'm an organ donator, so, if possible, I want them to use all my parts. Heart, eyes, liver, kidneys, skin, whatever someone else can use, I want it done. Pay it forward! If I live to be pretty old and my bits aren't going to last much longer than I, then I'm going to donate my body to science. I want it given to a local medical university to be used as a cadaver so medical students can learn to be doctors. My maternal grandparents did this, and there was a lovely ceremony in about a year after each of their deaths, where they bury the cremated remains of all the donors were interred. It was very moving. Both my parents have signed up for that upon their deaths.
And if neither of those are possible, I want my bones stripped and my skeleton on display/as a teaching aid!
