104-year-old Spanish chess player shares lessons learned from the game

104-year-old Manuel Álvarez Escudero, believed to be the world's oldest active registered chess player, continues to play weekly matches. He learned chess at 16 and credits the game with maintaining his mental acuity and, more importantly, fostering lifelong friendships. Álvarez, who survived the Spanish Civil War, also attributes his longevity to not smoking or drinking, and enjoys chess, football pools, and cards.
