David Nabarro’s frenetic lifestyle is clearly illustrative of the enormous responsibility with which he is charged: Senior Coordinator for Avian and Human Influenza for the entire United Nations system. It is perhaps just as well that the 56-year-old UN Assistant Secretary-General is an amateur runner, since he spends most days sprinting between back-to-back meetings, and multi-tasking with the energy and laser focus of a man half his age. His cellphone rings almost consistantly with calls from around the world and he clocks more international flying miles than most shuttle diplomats. “Currently, I’m working from 7 am to about 10 pm, seven days a week,” he said in January interview with The InterDependent. “I’m getting about five hours’ sleep a night.”
