Actually almost if-not everyone has the schizophrenia bornavirus embedded in their DNA.

Most people are able to code their epigenetic proteins to ignore it. People who can't code around the virus get schizophrenia. What causes people's epigenetic proteins to fail at this coding procedure? Nobody can provide you with proof. However there is pretty strong evidence.
Obviously when primate/humans incorporated this virus into our DNA a few million years ago we were able to code around it. Something changed. What changed? Mostly our diets. Generally the keys are to stop eating the grain, legume and nightshade agriculture crops, and to start eating meats, fats, and seafood.
Read these. They're long. Read them anyway.
