The is a very interesting and intriguing study conducted by Wayne State University in 2010. They looked at the Major League Baseball cards from 1952. They uncovered what maybe surprising for some but not for us here at Achieve the grin. The span of the players smile related to the span of their life! The larger the grin the longer they lived. Those with small ones lived on average 72.9 years but those with larger grins had an average of 79.9 years.
So keep smiling and make them massive 🙂
