In its “The New Old Age” section, Paula Span writes for the New York Times (6/4, Span) that “purpose,” while hard to define, is vital for aging, and according to one researcher, is “a very robust predictor of health and wellness in old age.” Dr. Patricia Boyle of the Rush Alzheimer’s Disease Center found that a study of 1,000 people over the age of 80 “found that the ones with high purpose scores were 2.4 times more likely to remain free of Alzheimer’s than those with low scores; they were also less likely to develop mild cognitive impairment, often a precursor.”
