Humor can be quite useful.
Let’s see how.
Suppose you are having a bad day (I realize this seems a bit dour and gloomy, but the venerated gallantry of well-placed humor will turn this around, wait and see).
While on the way home from work, you opt to use a ridesharing or ride-hailing service. After settling into the car and getting ready to have a quiet and solemnly introspective ride home, the driver suddenly speaks up and tells you an entertaining joke that causes you to laugh out loud. The merriment of the humorous anecdote sparks you to get out of your dismally sour mood. It was one of the best jokes you have ever heard, a knee-slapping and side-splitting piece of humor.
Things are looking up, and when you arrive home, your perspective and attitude about the world have shifted into one of peacefulness and content.
All due to letting some humor enter into your day.
