Bu here’s the exciting bit.
Following my heart led me to a conception of science, medicine and the world at large that was radically different from anything I was taught in school. My ideas, such as the heart is not a pump, blocked arteries are not the main cause of heart attacks, vaccines are ineffective and unsafe, cancer is not a genetic disease, and the “war on cancer” has been an utter failure, have been the subjects of three of my books.
Recently, because of current events, I turned my questioning gaze on the widely accepted theory —so accepted that it now lives in our culture as truth — that germs (bacteria and viruses) cause disease.
Tom’s views echo those of Andrew Kaufman, Sam Bailey, Mike Stone, Mike Donio, and many more.

I find their arguments convincing because they’re based on evidential, observable science; not speculation. And once you realise that SARS-CoV-2 (whatever that means) does not cause any disease, let alone “COVID-19”, a new paradigm of critical thought and interrogation emerges.
As the inventor of PCR – Kary Mullis – said, science is not about being right; it’s about being wrong.
