New Scientist.com: 11 Steps to a Better Brain
Opening paragraph: "It doesn't matter how brainy you are or how much education you've had - you can still improve and expand your mind. Boosting your mental faculties doesn't have to mean studying hard or becoming a reclusive book worm. There are lots of tricks, techniques and habits, as well as changes to your lifestyle, diet and behaviour that can help you flex your grey matter and get the best out of your brain cells. And here are 11 of them."
It does start out with "Smart Drugs"; some of which sound interesting... though I have some mixed feelings about some of that.. Back a few years ago, I started using things like Ginko Biloba and Ginseng, for energy and a mental boost with no apparent bad side effects and some noticed (placebo effect?) improvements when I am tired or having a meno-fog/ senior moment sort of day. Something targeted more to the actual neurotransmitters involved would seem a better way to go. (I know I saw a blogger I like, write something about all of this recently, but can't remember who or where- ;-D ; Future Pundit maybe? )
At any rate the article only begins there, it goes on to suggest some things that I have heard before in other places. All in all, it is an interesting group of suggestions.
