In college we were taught, +ve ground means the wires and electric items in the car are -ve , oxygen is a +ve atom and is attracted to -ve wire etc, causing them to corrode and fail... very expensive repairs replacing wiring etc...., so the battery was turned around to protect the wires and electrics components, but now the panels will rust,..

What would a child be if the father was B positive and the mother was O positive?

I am O positive and my husband is B+. We have two children. Our first child, a daughter, had O+ blood type. Our second child, a son, had B+ blood type. He was born with high levels of bilirubin (had jaundice). In the old days they would do a blood transfusion (which I am opposed to) but now almost all cases are treated with exposure to special lighting. We stopped there.

Will noxipro show up positive in drug test?

yes, you will test positive for amphetamines, sorry but I know this first hand, and before anybody says I'm some sort of drug user.... No, I'm not. I also know a few other guys who have used it and also tested positive. "These guys are all cops at the same PD," They've stopped taking it. Great product but to some of us, not worth risking our job over it.
