Bodies - the exibition

You may have heard about the exibition of human bodies. I visited it last Sunday in Prague and have very miscellaneous feelings. Well, it is very interesting from a medical point of view - you can see every inner detail directly on a dead human body which is conserved (all the liquids are replaced by a silicone rubber). Every bit of entrails from different angles. But, you still know it is a dead body. It is a strange feeling if you imagine it might be your friend's body or yours! I know the people have agreed their bodies will be used for this purpose, but still: do we need to present the human entrails in such a way? Isn't it possilbe to create absolutely authentic models eg. from plastic?
You may ask, why I went there if don't agree. Well, I was curious. But now I see I very much believe our spiritis, souls and bodies are interconnected and we should not split them and exhibit.
