I still think PATM is related to race...
French people produce pheromones that pure-blooded French people find pleasurable—meaning they won't sneeze in response to those specific pheromones—because pheromone receptors differ between the French and the rest of the world... but then someone might say, "Well, I know white French people who dislike my scent and sneeze non-stop around my PATM"... —those people don't have 100% French DNA; they carry DNA from other regions of the world, that's why their receptors are different, causing them to feel aversion and disgust and to sneeze instead of feeling pleasure... since it's very common in France not to have 100% French DNA, the likelihood of having a different pheromone receptor is very high... that is the true cause of PATM... but then there's Japan—a different race—and perhaps, just perhaps, the French and Japanese share this pheromone (androstenone) in common, yet possess other, distinct pheromones unique to their respective races... or maybe those Japanese individuals with PATM actually possess French DNA and the French pheromone...
