I have just viewed this video by Barrie Trower on the Major health consequences of WiFi and Microwaves on our health and the genetic health of all females.
The punch line here is that wifi and rf radiation is damaging the mitochondrial DNA of the eggs in the yet unborn female fetus and this is a permanent damage that cannot be undone.
This means that if a female is newly pregnant (first 100 days) and has been irradiated with WiFi or other microwave radiation, then there is a distinct possibility that the children of her daughter, not yet born, will have some damage to the mitochondrial DNA.
