But at some point, you touch or rub one of your eyes. The virus is washed into the moisture of the eye, washed down through the eye's drainage tube into the back of your throat and that is where the virus enters a cell in the lining of your throat and starts its parasitic life cycle. The eye is the point of vulnerability. It is a vulnerable opening, a chink in your armor, and that is where your defenses can be breached by a virus.
And just as a virus comes in through our body's points of vulnerability, the lamprey of the mind infects us through specific points of vulnerability. We have four main places where negativity can invade:
1. The brain. We have a brain that evolved to pay special attention to potential danger.
2. Communication. We have a strong, biologically-driven urge to be accepted by others.
3. The nature of reality. The lamprey can invade us through the inevitably misleading experiences we get under certain conditions.
4. The media. Perhaps most powerfully, we can be infected through a mutation called television. TV functions like the Erie canal, opening us to unprecedented numbers of lampreys we have developed no natural defense against.
