Not maintaining a healthy weight.

Not exercising.

Not quitting smoking.

Doctors say these things do help.

But as amazing as it may seem, simply smiling adds years to our lives.

Researchers studied the smiles of 196 baseball players based on their pictures taken in 1952.  The non-smilers lived an average of 72.9 years.

But those who smiled lived to be 75 – almost three full years longer simply by smiling.

And those who were pictured with so-called Duchenne smiles which engage the muscles of both the mouth and the eyes lived an average of 79.9 years – almost 7 extra years by lightening up.

Being a sour puss robs us of valuable years.

Here’s the study – fascinating reading.

Since, as the song “Smiling Faces” reminds us, a smile is just a frown turned upside down, we now have the best motivation ever to permanently put a grin on our faces.
