“Speaking of smiles. Did you know that when you smile, your facial muscles contract in a way that it, in turn, sends a signal back to your brain, increasing your level of happy hormones or endorphins? When our brain feels happy, we smile, and when we smile, our brain feels happy. It’s a pretty good arrangement, I think. In fact, it makes me smile just to think about it.” From ‘Life’s Journey Volume 1’. by Jon Gleman
