This book contributes to the discussion on the ageing society by addressing the new psycho-social structures of the ageing society, the problems around family bonds and ties, and the structures of care and protection. The book sheds light on the new roles of grandparents and new grandparents, and the empowerment and resilience initiatives, thereby providing a broad discussion of what the ageing society implies in psychosocial terms. These issues are addressed in an interdisciplinary way, but also in an approach that is also rare, comparing different realities between Europe and Latin America. The [basis of the] English translation of this book from its Spanish original manuscript was done with the help of artificial intelligence. A subsequent human revision of the content was done by the author.
