We all know how much fun dancing can be. It can breathe new life into a tired soul, make a spirit soar, unleash locked-away creativity, unite generations and cultures, inspire new romances or rekindle old ones, trigger long-forgotten memories, and turn sadness into joy.On a more physical level, dancing can give you a great mind-body workout. Researchers are learning that regular physical activity in general can help keep your body, including your brain, healthy as you age. Exercise increases the level of brain chemicals that encourage nerve cells to grow. Dancing that requires you to remember dance steps and sequences boosts brain power by improving memory skills.
