This video is really cool. Quite inspiring to say the least. I was researching the physiology of smiling and after reading about the uncertainty of how many muscles it takes to smile versus frown, I said to myself who cares really. Even if smiling takes more muscles than frowning, in the end it is always better to smile. Positive energy is emitted therefore positive energy is returned.
Enjoy and remember to smile often
As always, I welcome your thought, comments, and observations.
Wishing you much happiness and success!
