Unfortunately... whenever I eat more than a threshold amount of onion, it gets into my bloodstream or something, because the next thing I know, my entire body smells vaguely of onion, for the next several days. Not my breath, my entire body. I sweat onion, even though I seem to be the only one fine-tuned enough to notice it. And that does not please me. I first noticed this my teenage years, right in the summer of 1996, the summer my father showed me how to make the perfect salad.
One more flaw in the illusion of perfection.
