I know a clown who works with adults to use humor in their lives. Recently, a group of children were asked why they think she might choose to work with adults. They responded that perhaps it was because children have an easier time laughing and playing, and adults need to remember how to do that.
Where do you find joy and laughter? Think about a recent moment of joy and hold it in your heart for a moment.
I work with an organization whose primary day-to-day function is to help veteran patients laugh. Such patients in hospitals and long-term nursing homes do not see much to laugh about. Serving as chaplain to such a group is a study in putting the spiritual into active use in the physical. I find it interesting that many who do this work never see the spiritual beauty of their efforts.
