Crosswords, Sudoku, anagrams, brainteasers, trivia challenges—the list goes on! These terms are known to virtually everyone. But what you may not know is that such apparently "trivial amusements" also foster brain growth by stimulating logical and creative thinking regions of the brain. Research has, in fact, come forward recently to suggest (although not prove beyond a shadow of a doubt) that puzzles sharpen the mind, improve memory and keep the brain fit throughout life, especially in later life.
