Simon is fairly well-positioned to avoid the cold. Genetically, his father has doubtless contributed his Iron Constitution that led to him missing exactly zero school days due to illness all the way through sixth grade. And his mother, of course, passed on the Comprehensive Resistance she developed to every communicable disease passed on by the girls of St. Mary’s Academy. Finally, I’m thinking of teaching him some ninja tactics to evade airborne pathogens: “Simon, you must learn to think like a rhinovirus! Be the rhinovirus! And wear this headband.”
