I remember a rumor going around that the Francis Bitter National Magnet Lab at MIT used to have a larger than normal (whatever that means) incidence of leukemia among the researchers exposed to intense fields. NWIH I would lay down in a field every night.
Some magnets at the head--temples area I think--can evidently truly cure depression for extended periods.
And some insist that it helps align or some such the iron in the blood to function more healthfully.
I do think more research of a quality nature should be done and prevented from being trashed by the greedy drug companies.
