Positive consequences of an ageing population

It is now and then difficult to find that many pros of having an ageing population. That's why listening to this http://sverigesradio.se/sida/gruppsida.aspx?programid=1650&grupp=7013&artikel=4394730  got my attention. A study is showing that is seems to become more and more common that grandparents help their children in domestic chores, everything from fetching the kids from kindergarten or school, to help out with the garden and the house. The older generation is healthier than ever before and can obviously participate and help in a way that they never could before.
