First off I think you are the owner of that Hungarian gore website with the red watermarks.
Second I don't think children should be taken to autopsies, definately not pleasant and the smell of a freshly opened corpse is unlike anything else in the world so definately not a good idea, children can be traumatized for life.
Modern people are not exposed to corpses because they fear their own deaths and they fear deaths of their relatives so any reminder of death and dying should be kept away.
Still there are people who are born necrophiles and then go on to take jobs as forensic experts, funeral directors, etc etc. It's in our genes.
Anyone who chooses to work in a morgue or funeral home is a necrophile, there is just no other way, go to a real morgue and see for your self.
Even the best high-techs morgues smell of rotten bodies, there is just no way to avoid that smell, pleasant to some, horrible to others.
Normal people wouldn't be able to stand it for one minute, but for me and other necros it's a plesant aroma and I can get hard just by the smell of a dead body.
