Let’s look at Proverbs 17:22 in a few different translations:
A cheerful heart is good medicine, but a crushed spirit dries up the bones. NIV
A cheerful heart is good medicine, but a broken spirit saps a person’s strength. NLT
A joyful heart is good medicine, but a crushed spirit dries up the bones. ESV
A merry heart doeth good like a medicine: but a broken spirit drieth the bones. KJV
It’s so good to have different translations of the scripture, it helps you see In and around the thoughts that God was presenting.
When we cheer up, we do more good for our health than any other natural thing.
