The segment profiles Dr. Anthony Fauci as he prepares to leave the NIH after 54 years (serving seven presidents) and begin a new chapter he insists is not “retirement.” In an interview with Dr. Jennifer Ashton, Fauci says he feels decades younger and credits his vitality to healthy habits, moderation, regular exercise (walks/running), strong purpose in his work, and good genetics. Viewers see his demanding routine—up at 5 a.m., working up to 18 hours—and his diet preferences (often fish and pasta; likes garlic salt; rarely eats lunch; limited alcohol) along with his strong health metrics. His wife, Dr. Christine Grady, describes providing crucial support by nudging him to eat, hydrate, and sleep, especially during the early COVID-19 months. Fauci reflects on how strange it will feel to stop commuting to the NIH, discusses limited social media use, and looks ahead to family time, travel, reading, sports fandom, and becoming a first-time grandfather.
