Hans-Werner Wahl, Hermann Brenner, Heidrun Mollenkopf, Dietrich Rothenbacher and Christoph Rott Ageing research has been identi?ed as a prototypical ?eld of inquiry deserving the full exploitation of single discipline approaches and interdisciplinary synergies amongst these single perspectives. Although this is a generally accepted insight, there still is a strong need to provide models of how this global and most fundamental challenge can be dealt with. It seems in any case necessary to narrow down the wide scope of ageing research issues to sets of key constructs most promising in terms of interdisciplinary cross-fertilisation. Againstthis,themajoraimofthebookistoprovideacomprehensive treatment of one well-selected set of key issues of recent ageing research, i. e. health, competence and well-being. In addition, the book's ambition is to identify priorities for future ageing research and to further new avenues for interdisciplinary approaches and social policy applications. The substance of the book is based on an international conference which took place on June 18 and 19, 2004 in Heidelberg, Germany. Framed within the array of health, competence and well-being perspectives in ageing research, the idea of the conf- ence was to provide an integrated presentation of ?ndings generated in the German Centre for Research on Ageing at the University of Heidelberg (Deutsches Zentrum f. ur Alternsforschung, DZFA). The centre's three departments, i. e.
