Quote by Oliver Wendell Holmes
Men do not quit playing because they grow old; they grow old because they quit playing.
Summary
This quote suggests that the act of playing and engaging in playful activities is important for maintaining a youthful spirit and mindset. It implies that it is not the passage of time itself that causes people to grow old, but rather the loss of enthusiasm, curiosity, and sense of adventure that often comes with quitting playful pursuits. By continuing to engage in playful activities throughout life, individuals can potentially stay vibrant, energetic, and young at heart.
