No i took all those factors in environment, food, genetics, etc...
But you have my attention if you would be so kind to enlighten me on karma.
So you put in the factors of if
the parents smoke, drink during pregnancy and after,
the parents were taking medications.,
the parents were feeding her GMO foods or eating it themselves
leaved in areas with high concentrations of cancer producing elements like living near Electric Power Lines, Nuclear Power Plants, chemical dumping plants, mines?
There are many factors to it...PM me and I send you the rest.
Sometimes Karma isn't just on the individual own personal self but others surrounding him/her. I seen it where someone was an a$$hole all his life, treating people bad but Karma didn't get him, it got to his wife and kids. It's a life-teacher that brings joy and pain, regardless of the situation. It suppose to bring a message/lesson to those who use it for good and those who use it for bad. Wither we agree with it or not, it serves it's purpose.
