“Pretty much at every age, women seem to survive better than men,” says Steven Austad, an international expert on ageing, and chair of the biology department at the University of Alabama. For almost two decades, he has been studying one of the best-known yet under-researched facts of human biology: that women live longer than men. His longevity database shows that all over the world and as far back as records have been kept, women outlive men by around five or six years. He describes them as being more “robust”.
