Proverbs 17:22 says, “A merry heart doeth good like a medicine.”

My kids at summer camp give me plenty to be merry about. For example, one little girl, six, talked about the fact I bring in and eat popcorn each day.
“Yes,” I said, “I eat it every day.”
“Well, that’s not good for you,” she responded.
“Why not?”
“Because you need to eat fruits and vegetables.”
