"The present and future of our society are shaped by an ever-increasing proportion of old and very old people. The Berlin Aging Study is one of the largest interdisciplinary efforts to explore old age and aging. Unique aspects of the Berlin Aging Study are the spectrum of scientific disciplines involved, the range of discipline-specific and interdisciplinary research topics, the focus on very old age (70 to over 100 years), and the empirical reference to a representative heterogenous urban population."--Jacket.
