Add a gift receipt for easy returns. According to the Ferromagnetic Cancer Theory (Theory from the Old Testament; Iron Conception), any human cell should be interpreted: 1) as a society of atoms and molecules; 2) as a society of organelles; 3) as a society of dia-, para-, superpara-, ferri- and ferromagnetic nanoparticles that have certain local magnetic contacts. I may have extrapolated that. What this means is that harvesting sharks is generally not sustainable. R. Robbins, B. Bruce, A.

Any cancer is caused by iron-related genes (numerous genes directly/indirectly involved in iron metabolism / hereditary cancers) and iron-related events (when excess iron accumulates within the cells, tissues, and organs due to various carcinogenic lifestyle events / sporadic cancers). [6], After Sharks Dont Get Cancer was published, Lane's claims received further publicity from segments on 60 Minutes in 1993.
