It is difficult for me to answer this question. I can detect a bad smell in my nose and throat pretty much all the time. I notice that sugar and bad carbs makes the smell terribly worse.
Maybe, I wouldnt have paid attention to it if I would have happened to pass by a person with PATM because didnt know something like that exists.
I believe thats why I havent been called out because its not the first thing somebody getting allergic reaction is a other person.
