I am listed as an organ donor, so bits of me might be taken away. I was going to say cremated and put in an urn which my wife will put in a shrine that she can pick up in Chinatown and put lights on it. (If I were rich and influential, I might do something like Jeremy Bentham and have myself put in a glass case, and give my money to a university with the requirement that I forever more attend meetings at the highest level, or they don't get the money.) But your idea of being put in a refrigerator uncovered has a certain appeal to it as well.
Of course, once I am dead, I will not care. So the above is just a bit of fun. It it unimportant to me what happens to my body after I am dead.
"A wise man ... proportions his belief to the evidence."
