Well, I can tell you how bad it can be. It involves doing research about one's grandparents. It's unfair to people whose grandparents are deceased because those people can't get a direct source of information about them, whereas people whose grandparents are still alive have easy access to this kind of information. My grandparents are dead. Both sets. The only pair I can actually get information for is from my father's side because we have family down here. My mother's side is in South Korea, so I only have two sources for my mother's side, those being my mother and father, and a number of sources from my father's side, mother; father; aunts; uncles. That's another factor of how bad it can be.
