New York Times, 5/22/09, "At the Bridge Table, Nonagenarians Offer Some Clues to a Lucid Old Age."
Some ladies in Laguna Woods, California that are 90 and older play bridge. They say that they play bridge for blood. By this they mean blood is vital for life and playing bridge is vital for their life. It's what keeps their brain active and healthy. Not only does it keep their brain lucid, it's fun too and they get to play it with their friends.
Irvine University scientists have been interested in what they call the super memory club. Some older people have lived past 90 without a trace of dementia. These are the most successful agers on earth and they're only just beginning to teach us what's important in the success agers genes.
dementia = mental function deterioration
vital = important
bridge = card game and involves a lot of math and thinking.
