Smile, and you may live longer.

Smile, and you may live longer.

BIG smile? Longer still.

Wayne State University researchers collected photos of 230 Major League
Baseball players who started their careers before 1950. Independent reviewers,
who were not aware of the study's purpose, categorized the photos, sorting
each into one of three groups: non-smilers, smilers, and big smilers.

When the smile rankings were matched against each player's lifespan, researchers
found a very strong link between smiling and longevity.

These were the average life spans:
* Non-smilers: 72.9
* Smilers: 75
* Big smilers: 79.9

Of course, this doesn't offer proof that a frequent smile will actually help you live
longer. But consider this: Some Zen Buddhists believe that starting off every morning
with a good long laugh is equal to the calming effect of several hours of meditation.

Also, studies have shown that smiling or laughing prompts the release of endorphins
and serotonin -- brain chemicals that improve mood.

No guarantees a smile will add seven years to your life, but you know what they say:
at least people will wonder what you've been up to.
