I found this article in the UK Guardian very interesting. Makes a lot of sense to me- exercise your mind, feed it brain food and reap the rewards. An excerpt from the article:
"THE GET SMARTER GUIDE
Brush your teeth with your 'wrong' hand and take a shower with your eyes closed.
Do the crossword or Sudoku puzzle in your Sunday paper and take a brisk walk.
Have oily fish for dinner, and either cycle, walk or take the bus into work.
Select unfamiliar words from the dictionary and work them into conversations.
Go to yoga, Pilates or a meditation class, and talk to someone you don't know.
Take a different route to work; watch Countdown or Brainteaser.
Avoid caffeine or alcohol; memorise your shopping list."
Once you have the basics in place, then you can add high-purity supplements for additional benefits.
Ortho-Mind or the sustained release R-Lipoic and ALCAR combo
Aniracetam or Piracetam
Enjoy your body and brain - make the most of your opportunities in life!
