When you have lost loved ones to cancer -
Excuse me if you aren't the only one to have gone through that.
and watched them suffer horrendously and miserably after receiving chemotherapy "treatments" -
Or not. Different people react differently to differente chemotherapy treatments.
only to have their last days on earth be an agonzing, living hell for them -
Sorry for that to be your case. Fortunately, chemotherapy actually avoids that fate in many cases.
you start to question the validity of these treatments and begin open yourself up to the possibility that others who have had a very measurable success with unorthodox treatments may very well be onto something very real and special.
Until you notice that they have had no measurable success, that they are based on quack science (cancer grows on acidity? How does that explain leukemia?), and that, actually, some of them have narrowly escaped being sentenced to prison for manslaughter.
