Train your Brain
The New York Times reports on a study that shows that training your memory improves your overall intelligence:
Until now, it had been widely assumed that the kind of mental ability that allows us to solve new problems without having any relevant previous experience — what psychologists call fluid intelligence — is innate and cannot be taught though people can raise their grades on tests of it by practicing.
But in the new study, researchers describe a method for improving this skill, along with experiments to prove it works.
(Thanks for the heads-up, honey.)
