Don't you remember from all those old-time ads that it takes ~72 tightened muscles to frown, and only 3 or so (?) to smile :-)???
I am so very happy for you, and thanks for making the experiment, too! And posting your results! Congratulations!
I'm going to try that! :-) :-)
Good Health to All of Us,
Ladylove :-)
PS: You inspire me :-). There are so many experiments I am waiting to get the chance to make.. Nevertheless, one by one, they get done :-)..
