I would not want to know, ever.
I would only want to know when/if I needed an organ or bone marrow transplant.
I would only want to know the facts for now, it might explain a few things is all.
I would want to know, but get familial medical information only.
I would want to know, and exchange letters through an intermediary only.
I would want to know, we could be facebook friends for starters. (That way I can unfriend the weird ones)
I would want to know, and meet my immediate bio family face to face (No TV cameras please!).
I would want to know, and meet the entire bio clan! When is the next reunion?
