Article in the Comox Valley Echo (British Columbia, Canada) about square dancing.

A major 21 year study led by the Albert Einstein College of Medicine in New York City with a focus on whether physical or cognitive recreational activities influenced mental acuity. They studied such activities as reading, writing, crossword puzzles, playing cards and playing musical instruments. They also studied physical activities like tennis or golf, swimming, cycling, dancing and walking. Dancing came out near the top as an activity that assists in rewiring our neural pathways and thereby helping our mental acuity. Dancing integrates several brain functions at once – kinesthetic, rational, musical and emotional. And square dancers experience all of this and more!
