I enjoy hearing stories, reading names and places and imagining what people's lives were like. Basically... I like all the fun things without the work. That's a fail for me.
Not everyone is as lame as me though, thankfully, and we can all benefit from the connection family history gives us to our ancestors.
"I saw behind me those who had gone, and before me those who are to come. I looked back and saw my father, and his father, and all our fathers, and in front to see my son, and his son, and the sons upon sons beyond.
