I was reminded today that as adults, we often let go of the activities of youth. We do this because we get busy with other things - kids, careers, new relationships. The upside of this is that we learn more and experience new things.
The downside is that we sometimes let go of things that brought us joy.
It merits saying that there is nothing wrong with playing - as adults. Whether it's a sport, an instrument, a game - there is value in taking time to play.
In some instances it keeps us fit, in others nimble. There are times playing can keep us mentally sharp. Just as valuable, playing keeps us young. The joy that comes from playing is not just available to the young, but to those of us who have entered adulthood. And it is that joy that keeps us young at heart.
