One value of older people is that they are increasingly useful as grandparents for offering high-quality childcare to their grandchildren, if they choose to do it, as more young women enter the workforce and as fewer young parents of either gender stay home as full-time caretakers of their children.
老人的一个价值是他们 作为祖父母， 在为其孙辈提供高品质的儿童照顾上 越来越有用，如果他们选择做这件事， 因为越来越多的年轻妇女参与劳动 以及越来越少的年轻父母中任一一方 留在家里全职照顾他们的孩子。
