The segment profiles Dr. Anthony Fauci as he prepares to leave the NIH after 54 years, emphasizing that he’s not “retiring” but moving to a new chapter. Dr. Jennifer Ashton explores his “longevity” habits: strong sense of purpose, staying active with daily brisk walks and a history of running and sports, and moderation in eating and drinking (often skipping lunch). Fauci credits good genes—his father lived to 97—but also consistent healthy living; he enjoys fish and pasta and admits a fondness for salt despite excellent blood pressure. The piece highlights his demanding routine (up at 5 a.m., working up to 18-hour days) and the support of his wife, Dr. Christine Grady, who helps ensure he eats, hydrates, and sleeps—especially during the intense early months of COVID. Fauci discusses the adjustment of no longer commuting to NIH daily, notes he’s not active on social media (though he may be in future), and looks ahead to family time, travel, reading, sports, and becoming a first-time grandfather, while remaining committed to impactful work.
