The Martínez-González brothers recognize that the book they have written, Healing on fire it is “controversial” and “incendiary”. “My brother and I do not mince words,” says one of them, Miguel Ángel, an epidemiologist specializing in preventive medicine and public health. He participates in the conversation from his home office, which is hidden behind a virtual background of one of the “cyber” of the Carlos III Health Institute, the Ciberobn (Center for Biomedical Research in Network of Physiopathology of Obesity and Nutrition) in which is head of the research group. The best known facet of Dr. Martínez-González focuses on the Mediterranean diet and health habits; your book What are you eating? is a recent best seller. The other doctor Martínez-González, Julio, joins the video call on his mobile, confined for a while in the small bedroom where they sleep, that is, the guards at the Regional University Hospital of Malaga, the people who attended the emergency of the coronavirus in 2020. He shows with the camera two side tables, two narrow windows with blue American blinds that barely stop the light, a flexo, a single bed and two bunk beds that he describes as “ramshackle.” Julio focuses on the ceiling to show us the vent. “It is huge – ironizes – at least 20 centimeters, and also shares ventilation with the COVID rooms that we had next to us.” Now that wing is already closed.
