Researchers have been studying “SuperAgers”, and the associated phenomenon of SuperAging, to discover possible physiological and genetic mechanisms behind the fortuitous preservation of superior memory into old age.
‘Super agers’ offer clue to keeping a sharp memory. London: BBC Health News, September 14th 2016.
