About SUDOKU BOOK FOR ADULTS: 1100+ Easy To Super Hard
Did you know that Sudoku May Help Keep Your Brain 10 Years Younger? A study conducted by the International Journal of Geriatric Psychiatry (PROTECT study *) identified a close relationship between frequency of number-puzzle use and the quality of cognitive functions in adults over 50. In particular, the study also found that people who do puzzles regularly have brain function equivalent to 10 years younger than their age. These findings further contribute to the growing evidence that engaging in mentally stimulating activities could benefit the brain functionality. *https://pubmed.ncbi.nlm.nih.gov/30746778/ Challenge your mind and enjoy hours of fun with this standout and quality Sudoku book for adults.
