Understanding the Aging Brain

My grandfather, who lived to be ninety-four, always insisted that the secret of a long and lucid life was to keep active, interested, and busy. When he was about 40, he wrote a letter to his local newspaper expressing some trenchant opinions about the current state of the economy. Fifty-four years later, just before he died, he was still sharing his opinion through social media outlets like Facebook about dogs, Notre Dame football, millennials, and all the myriad other subjects that caught his far-ranging attention. He may have been ninety-four, but his mind had remained supple and young.
