Well the fact is neither the body nor the brain has a firewall, external forces (accidental or by design) can drastically change biological systems in us. For example I was amazed when I found out that cell phone waves unwind your D.N.A . If you reverse engineer that it means our D.N.A are antenna receiving man made powerful signals that are changing the cell structure in ways we don't want to happen. The body has to repair that unwinding. That is just one aspect of the subject, take the brain for example, it is very easy to change brain chemistry from long distance Telemetering.
The following document is a scientific journal showing the ability to do this since 1960's. So what I am saying is everything has been weaponized in our society and the ability to directly transmit neural information to every brain on earth at once as the following journal says, is mankind's worst nightmare.
