I have encountered many pundits screaming the demand that all genealogy MUST be shared, open, and available to all (no, it does not). Funny they never care about the quality of what gets shared. I encountered many others just screaming anything in an effort to simply grow the pool of potential money for themselves.
The surprising thing is that most religious leaders, even in parts of the world where the family is "extended" sometimes beyond breaking point, adopt the default definition. Whether in Friday khutba or Sunday preaching, Synagogue or Temple, you will be lucky to hear the word "grandparents" in a sermon on the family.
For parents, grandparents and carers there is no better way to learn about your children than to play with them. Every child is a unique individual with their own special styles of learning and ways of looking at the world, and the more you understand about this the more prepared you will be to support them in their everyday lives.
It's hardly surprising that so few of us are looking forward to getting old. While most people can appreciate that it's better than the alternative, a lot of the time it's not that much better. Never before in human history have so many of us lived so long, and we're singularly ill-prepared for this change in the shape of human lives.
