OLD DOGS, NEW TRICKS:

Old beagles, like old humans, act younger and smarter when they get the right diet and plenty of intellectual stimulation. A report published in the January issue of Neurobiology of Aging found that a diet rich in antioxidants combined with a stimulating environment slowed the canine aging process. . . .

By the end of the two-year trial, it was clear that the enriched diet alone and the enriched environment alone were each helpful in preventing decline. But the mental functioning of the dogs given a combination of enriched diet and stimulating environment was considerably higher than that of the dogs in the other three groups, the researchers found.

Maybe there’s hope for Dan Rather.
