Gretchen Reynolds New York Times International edition excerpts from a much longer article on research published in Frontiers in Aging Neuroscience... A new study that compared the neurological effects of country dancing with those of walking and other activities suggest that there may be something unique about learning a social dance. The demands it places on the mind and body could make it unusually potent at slowing some of the changes inside our skulls that seem to otherwise inevitable with aging. . . . After six months...the dancers had denser white matter in their formix, apart of the brain involved with the processing speed and memory. Note that their "country" dancing was not country western as I know it.
