Right, but that means that environment plays a part too, because not all those with the gene develop it.
Agreed - see my reply #20
Thank you, someone who gets what I said, as well as what I meant.
When they say environment ( I don’t think of weather, fog, or environmental) I think it s more about where they go and what they are exposed to.... meaning their twin sibling may not have been exposed to the same thing. Such as toxins at a place where it’s unknown, etc. Do you know what I mean there?
