You be the judge of this. I think you will know my demented thoughts on this. The gene one only covers to my understanding maybe 5% of people who get AD. I would really like to know how they determine that the one's that did not get AD, would not have gotten it anyway. Stats can mean what you want them to.
God Bless & Keep You & This Country of Ours!
