This is a nutshell explanation of Dr. Cowan's talks about virology and how scientists claim viruses are isolated. He has his own channel and many more videos that go into greater detail.
He was drummed out of the Rockefeller Medical Industrial Complex for not following their rules. He wants to actually treat/heal people and that is not in line with modern "healthcare".
Well, I had a female cat that died of cancer of the breast and she had three litters of kittens -that obviously did not protect her.
I think a lot of the blame lies in the crap that's in the food, human and animal alike.
My mother had 10 children. She had gestational diabetes and ended up dying from breast cancer.
All these studies of "so and so has a higher risk of such and such based on blah blah blah" is bullshit.
LOL at downvoters.
