The six-year-old Utah boy was sick for no clear reason. Just bad luck. For years, he had terrible sinus problems, and doctors assumed that it was bacterial, prescribing antibiotic after antibiotic that never solved the problem. Then one physician looked outside of the box (outside of the nostril?) a bit and noticed that there was some kind of foreign object up the child’s nose. Did he remember putting anything up there? No, of course not. A specialist removed the obstruction, which turned out to be a “ball of fungus” surrounding a tiny, flexible LEGO tire. The child’s health problems abruptly disappeared.
