IPOTHESIS ABOUT THE RINGS
I think rings work mainly through increasing Van Der Waals forces in all the body,so that molecules and cells attract and interact better.

That doesn't make any sense. You don't understand how Van Der Waals forces work very well. The only way I could see it work is if this increase in 'flux' increase the speed of electrons in their valance orbits. In which case, that would be very apparent. I don't think there's any evidence that magnetism can do that. Tell me if you find some. Also... Hypothesis?
