The first crosswords appeared in England during the 19th century. The first known published crossword puzzle was created by a journalist named Arthur Wynne from Liverpool. It appeared in a Sunday newspaper, the New York World.
During the early 1920's other newspapers picked up the newly discovered pastime and within a decade crossword puzzles were featured in almost all American newspapers.
According to Dr. Gary Small, the director of the UCLA Center on Aging, "Our brains age just the way our bodies age, but there's a lot that we can do to fight against it and keep ourselves mentally fit."
Sudoku puzzles have recently become an extremely popular hobby, and great method of working out your brain, but thanks to new technologies there are a huge variety of interactive sodokus and crosswords online.
