And what’s with all the vomiting that goes on in some stories? Do people really vomit *that* easily? In front of other people?
Yes, sometimes they do. Even professionals. For example my mother. She was a nurse and she fainted when she was to observe an operation and she told me that she vomited very easily when she smelled someones vomit. That was one of the reasons why she had to use a face mask with two or three drops of peppermint oil.
