Have you been told by other people that you're laughing so poorly? When you take self-portraits, do you always laugh unnaturally in the photo? So don't you like to share your smiles or photos with everyone? There are many muscles in the face as there are in the body. The activity of speaking and smiling makes use of only a small fraction of the muscles in the face- not more than about 30 percent. The muscles that are not in use begin to wane and fade away, especially as one begins to age. The truth of the matter is that a good smile makes one look years younger than his or her age because there is more use made of the muscles and for a longer period of time. This increases blood flow around the parts that make up the face, to keep that part healthy and youthful.
