GuardianUnlimited has an article on Simple ways to make yourself far cleverer . Brain exercises such as watching countdown, playing Sudoku, remembering telephone numbers and taking a shower with your eyes closed can make us all up to 40 per cent cleverer within seven days, according to research by a BBC programme this week.
Here is the Get Smater 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.
