Demographic and economic aspects of ageingeady been made of the vital need to see elderly people as individuals and to avoid blanket theories, but to enable rational forward projection and planning to take place it is also essential to comprehend these demographic and economic aspects of our ageing population.令人发腻 发表于 2025-3-30 00:26:13
