I agree with you completely. I am no geneticist, but genetics is one of the last frontiers and there is still so much we don't understand. As much as I respect grz and Trapper, I don't buy their arguements. Your not in a box. Your on the ball. Genetics is everwhere. I had a uncle who died of a heart attack at 33, one at 49, and one at 60. My dad has been on heart medication since his early 30's. Many diseases, including certain types of cancer, seem to run in the family.
