Why 70 is the new 60 - an interview with Annette Baudisch (Max Planck Institute for Demographic Research) on biodemography. Questions: 1. When my grandmother was my age, I perceived her as being much older than I feel now. Is this just a question of perspective, or is being 70 today biologically different from what it used to be? 2. If you look at human ageing in a long-term perspective, what has changed most significantly since the Neanderthals?

Interview with Bruno Arpino (Universitat Pompeu Fabra) on health and grandparenting. Questions: 1. My daughter and her partner are expecting their first child. As they both have quite demanding jobs I would like to offer my help in looking after the baby, but I am also a bit worried that my other activities might suffer from this. What have you found to be realistic based on your research? 2. Is grandparenting as good of a social activity as being in a sport’s club or a choir in terms of benefits for an older person’s health?
