Summary
This quote suggests that advancing age does not inherently make someone old; rather, it is the loss of enthusiasm and interest in life that brings about a sense of oldness. Simply living and going through the motions of life is not enough to make a person feel aged, but when one starts to lose the zeal and curiosity that fuel their existence, the sense of old age sets in. It implies that staying engaged and finding purpose in life keeps us youthful, regardless of the passing of time.
