So tell me why I am borderline diabetic when none of my ancestors has ever had any diabetes?
Diet? Obesity? Viruses? Age?
Diabetes has numerous causes and genetics is only part of it. People with a family history are 25% more predisposed to get it.
Bluejay in no way said that he could predict whether you had diabetes base upon your family history, he stated "the likelihood of having diabetes".
Maybe you don't understand the difference between what he said and what you implied.
Facts don't lie or have an agenda. Facts are just facts
