I feel that our ancestors — living or dead — show us much about ourselves, and our expectations, presumptions, misconceptions. We need to learn about our ancestors and their lives. By learning about them, we honor them and our shared humanity. I’m not sure I understand or am aware of the “social taboo” you mentioned that exists about exploring the lives of living family members. Maybe our culture’s obsession with youth and/or age-ism are examples of this social taboo.
