Only the signal from the brain makes us sick or well. Our perception puts effectors into action and creates enzymes and other chemicals to **** germs or literally make us sick.

If you tell a child cancer runs in the family, then that child will probably get cancer if they believe it. For leaders not to tell the truth, it shows the AMA and big pharma are calling the shots.
