I just have to share the fact that laughing, smiling, and such are so contagious. i have observed that even if someone has a frown on their face...I can usually smile and at lest be rewarded a grin. So, why in the world would anyone want to waste their precious time and energy into something so unfulfilling as frowning. Try it sometime, and I am sure you will be amazed at the way you feel after you get s smile from someone in return. SO SMILE, LAUGH...and be happy, inside and out
