Quizplus · Accepted Answer

Staying physically and cognitively active has been proven to be one of the most effective ways to preserve brain functioning and slow down the decline of brain mass. Exercise increases blood flow to the brain, while cognitive activities such as puzzles and reading stimulate the brain to form new connections and maintain existing ones.
