Alzheimer's now 3rd leading cause of death, after heart disease and cancer

Excerpt: a study of aging patients suggests its true toll may top half a million lives a year -- a figure that would put Alzheimer's just below heart disease and cancer on the list of America's top killers. ..."The Alzheimer's Association has been saying for a long time that that 80,000 figure is a gross undercount," Fargo said. The new figures may help Americans realize that Alzheimer's isn't "just about forgetfulness," but "a universally fatal brain disease."

And how much is it being caused or exacerbated by the toxins (with chemtrails high on the list) polluting our planet?  That would make a good study.
