What a range of interesting opinions -- some very funny! I didn't mean to introduce the religious angle, but here's a thought. If a person's body needs to be "whole" for resurrection purposes, what about all the folks drowned at sea, eaten by wild animals, and so on?
# I'm not worried about being dug up because my will orders my cremation, and it's already paid for. However both my parents wanted to be buried in bronze caskets, and I didn't argue with them. I felt they deserved to have their final wishes carried out. Is it any different with people who died long ago? Didn't their families/tribes go to great expense and trouble over their graves? Just because we don't believe in their religion, do we have leave to ignore it?
# Sure it's great to learn about the way people lived in the past, but can't we draw a line somewhere? Dig up the ancient cities and they can find plenty of fascinating art, literature and technology, without bothering the graves.
# Still thinking about some of the other topics. Meanwhile, I'm leaving my brain to Science Fiction. == Johnny in Oklahoma City
