As a manufacturer and seller of zappers ( ParaZapper ), it always pleases me when I am contacted by those who are cancer survivors due to the work of Dr. Clark
A few days ago, I heard from another survivor of 14 years who thanks Dr. Clark for this part of her life.
She also left the following wisdom. Do not stop with Dr. Clark's early books but continue reading her later books and also watch her later speeches where ever they may be available.
