Dave Copeland went to the Body Worlds exhibit at the MoS, explains why he wouldn't go again:

... Some of the full figured models -- particularly the ones where hair and fingernails were preserved or where the person's facial features were still readily identifiable -- were disturbing. To me, at least. Again, I'm squeamish.

But the biggest bother to me is the display told nothing about who these people were before they were museum exhibits. Perhaps its the journalist in me who is a bit more interested in people's stories than their spleens. ...
