A number of studies have suggested that people who survive to extreme old age exhibit better immune function throughout later life in comparison to peers who died at earlier ages. This analysis is an example of the type, and the data shows a natural killer cell population that exhibits signs of greater efficiency and more youthful activity. How and why long-lived individuals exhibit better immune function is a separate question. Studies of genetic variation in very large human data sets suggest that genetics plays a much smaller role in late life survival than the consequences of lifestyle choices (such as physical fitness) and environment…
