Mishlei 15: 15
A person with a good heart / mind /attitude is always at a banquet.
We can ask - how big of a banquet ?
A recent study claims that a smile can be as stimulating as eating 2,000 chocolate bars !! ?
That sounds big.
Ps. Rav Wolbe writes in one of his seforim that animals do not have the capacity to smile as humans. We need to thank Hashem for the gift He has endowed us with & use it more !
Now may be a good time for a gem of Torah study.
