Well this certainly is good news for grandparents, and great news for my wife and me, as we love love love spending time with our little peanut. (BTW, I've got plenty of pics here and here, and a new one here!) This research shows that grandparents who look after their grandchildren at least once a week are less likely to develop Alzheimer's.

Although an exact reason for the correlation isn't clear, researchers speculate that regular social interaction can have a positive effect on seniors.
