What's One Easy Thing You Can Do Right Now to Live Longer?

What's one easy thing you can do right now to live longer? Pro baseball players who did it lived longer -- and so can you. Give up?

Smile :)

A new study found that:
People who smile a lot are usually happier, have more stable personalities, more stable marriages, better cognitive skills and better interpersonal skills, according to research. Science has just uncovered another benefit of a happy face. People who have big smiles live longer.

Researchers at Wayne State University used information from the Baseball Register to look a photos of 230 players who debuted in professional baseball before 1950. The players' photos were enlarged and a rating of their smile intensity was made (big smile, no smile, partial smile). The players' smile ratings were compared with data from deaths that occurred 2006 and 2009. The researchers then corrected their analysis to account for other factors associated with longevity, such as body mass index, career length, career precocity and college attendance.

For those players who had died, the researchers found longevity ranged from an average of 72.9 years for players with no smiles (63 players), to 75 years for players with partial smiles (64 players) to 79.9 years for players with big smiles (23 players).
