Want your parents to stay sharp throughout their golden years? Get them online.

Surfing the Internet gives elderly people serious brain power, according to the results of a new study.

Classic research shows a link between doing crossword puzzles and memory games, and a lowered risk of cognitive decline later in life, but now a study published in the "American Journal of Geriatric Psychiatry" says simple website searches play a role in keeping Grandma sharp.

When people between the ages of 55 and 76 searched the Internet, they make better decisions and had sound reasoning, compared to those who didn't go online. And get this -- web surfing improved areas of the brain that reading books could not.

Why do computers trump books? Being faced with a bevy of choices online (what to click, navigating the site) engages areas of the brain the elderly often don't use.

So what are you waiting for? Give Granny a "Superpoke!"
