Leading world's virologist Prof. Dr. John S Oxford from University of London, has experimentally confirmed claims by the Bosnian Pyramid discoverer Dr. Sam Osmanagich, Ph.D. about negative ions. Negative ions destroy all viruses, present and FUTURE. Number of other clinical studies found negative air ionizers wipe out hospital infections and prevented influenza virus transmission. Bosnian pyramid tunnels are ancient technology with the highest concentration of negative ions in the world. One of the purposes was self-healing process. Much needed scientific video describes how to fight viruses and illness. Note: Photograph at 52:49 would be a joke.
