Donated to medicine and science. If there's anything left (since priority would be medicine, sorry lads, no whole corpse means there's possibly some left which they wouldn't want) then burn it and scatter it into the sea (mostly to stop people keeping me around in a jar, no thanks).
I won't need it, I'll be dead and likely unable to care anymore. If I can then I like to think how much my body could give to people, rather than worms. I can't imagine letting people die simply because I find the idea a bit squeamish, it honestly boggles my mind. As it is, I don't find it weird (kinda cool, actually, but then I'm a scientist through and through) so no problems for me.
I wish donations were opt out...
