Just for fun, grab that old photo album and look for a picture of yourself. Are you flashing your pearly whites? Or do you appear as though you’re sucking on a sour lemon? Research shows that a wide grin may help add years to your life. HealthDay’s Kathleen Doheny says researchers from Wayne State University examined photos of Major League Baseball old-timers. Results may surprise you. It may even put that smile back on your face.

Not only should you smile, experience a  hearty laugh once in a while. An article from the University of Maryland Medical Center says laughter may help protect you against a heart attack.

After reading the HealthDay piece, I got to thinking about the “Duchenne Smile.” On Mindpub.com, Vijai P. Sharma, Ph.D, in an article titled A Genuine Smile Goes a “Long Way,” writes: According to Dr. Martin Seligman, the author of Authenic Happiness, there are two kinds of smiles, “The first called Duchenne Smile (after its discoverer Guillaume Duchenne) is genuine. The corners of the mouth turn up and the skin around the corners of your eyes crinkles (The crow’s feet). …The other smile, called the Pan American Smile (after the flight attendants in television ads for now-defunct airline), is inauthentic.”

So, put on your “Happy face” and see the benefits.
