He runs the trail at the Washington Duke Inn three times a week and on Fridays, he loops twice. He does not mind the scorching humidity of early June, because that’s when the smell of honeysuckle is most intoxicating. He watches women’s basketball games from the front row under the Duke basket and mentors female athletes interested in medicine through a program he co-directs with another top neurosurgeon, Dr. Henry Friedman (no relation). He leads a biweekly, Socratic discussion for first-year medical students called “brain school.” He enjoys poetry and has a copy of Marvell’s “To His Coy Mistress” on the corkboard behind his desk; he can even recite by memory the first, oft-quoted line.
