Searching the web boosts memory power but drinking shrinks your brain

Using Google may help stimulate much more activity in your brain as compared to reading a book. And this boosts brain power among middle-aged and older people. From BBC:
The researchers said that, compared to simple reading, the internet's wealth of choices required people to make decisions about what to click on in order to get the relevant information.

However, they suggested that newcomers to the web had not quite grasped the strategies needed to successfully carry out a web search.

Professor Smith said: "A simple, everyday task like searching the web appears to enhance brain circuitry in older adults, demonstrating that our brains are sensitive and can continue to learn as we grow older."
But the opposite happens when you drink alcohol. Any level of alcohol consumption leads to a decline in brain volume. Crikey! From CNN:
Overall, the more alcohol consumed, the smaller the brain volume, with abstainers having a higher brain volume than former drinkers, light drinkers (one to seven drinks per week), moderate drinkers (eight to 14 drinks per week), and heavy drinkers (14 or more drinks per week).

Men were more likely to be heavy drinkers than women. But the link between brain volume and alcohol wasn't as strong in men. For men, only those who were heavy drinkers had a smaller brain volume than those who consumed little or no alcohol.

In women, even moderate drinkers had a smaller brain volume than abstainers or former drinkers.

Ya... drinking too much will not only shrink your brain, it's bad for health too.
