A cheerful heart is good medicine,

Was at my mum's place this morning, when I had an upset tummy. Mum being mum always have the redemy at hand. I was given a type of "po chi pill" brand called Ban kah chai.
I was surprise to find a bookmark in the box with these words. "cheerful heart is good medicine" This of course is from proverbs 17:22 A cheerful heart is good medicine, but a crushed spirit dries up the bones . wonder if this guy have been reading proverbs. Guess what the medicine really works,just like the old brand I was so used to. Need to get some when going for mission ,especially those who has a weak stomach like me.
