Smiling can make others happy. "When you're smilin', the whole world smiles with you." Ever heard that song, made famous by Louis Armstrong? Well, it's true. Research shows that smiling is contagious. Ever been around someone who just had something fantastic happen to him or her? Isn't it almost impossible not to feel good, too? Studies show that something as simple as seeing a friend smile can activate the muscles in your face to make that same expression, without you even being aware that you are doing it. Crazy, right? ^_~
