For my daughter Lily, born premature in 2010, who weighed two pounds at birth and spent ninety-four days in the NICU at Columbus Children's. She is fifteen now. She runs cross-country. She wants to be a marine biologist. American medicine, American doctors, American nurses — they gave my daughter her life. This hex is for them, and for her, and for the next 250 years she will get to live through.
