The segment profiles Dr. Anthony Fauci as he prepares to leave the NIH after 54 years, emphasizing that he views it as a new chapter rather than retirement. Dr. Jennifer Ashton follows Fauci at home and work to uncover his “longevity” habits: maintaining a strong sense of purpose, staying physically active with daily brisk walks and running, and benefiting from good genetics. Fauci describes moderate eating and drinking (often skipping lunch), a diet featuring fish and pasta, and admits he likes salt/garlic salt while noting his healthy blood pressure and low pulse. Despite being nearly 82, he keeps an intense schedule—up at 5 a.m. and working up to 18-hour days—supported by his wife, NIH bioethics chief Dr. Christine Grady, who helps ensure he eats, hydrates, and sleeps. The piece also touches on his limited social media use, public admiration for him, and plans for the future including travel, reading, sports, spending time with his daughters, and becoming a first-time grandfather.
