Funnily enough, people find it so weird that I am barely affected by the over-dramatic gory driving videos and other shit, but when it comes down to real blood I get queasy. My friends have told me there was a drivers ed video with loud crashes, people screaming, blood everywhere etc. and I was dozing off in the corner
It's interesting the way things effect people. My aunt is big into horror movies. Probably watched all the saw franchise and whatever else. But she couldn't sit through the violence in Hotel Rwanda (which is extremely toned down, especially given the subject matter).
Apart from maybe bad smells
