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.But the opposite happens when you drink alcohol. Any level of alcohol consumption leads to a decline in brain volume. Crikey! From CNN:
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."
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.
