This book is part of a broad process of reflection on ageing as a rewarding experience. It is an important turning point in this process of knowledge production. It aims to deepen ongoing debates about contemporary society and its relationship with healthy ageing, responding to some of the demands of longevity. In structuring the themes, two demands influenced the division: to understand the process of population ageing and to present the actions that have an impact on the process of healthy ageing. In short, in one way or another, all the experts cited here, from different perspectives, point to society's strategic role in ageing as a rewarding experience. The depth given to section 8 on activities outside the family nucleus as a promising element of independence for older women will make this book an obligatory reference for policy makers and activists from the most diverse social organisations.
