Pieces of me

A blog for the warriors

Being an introvert, I’ve been misinterpreted as being rude or snotty. Smiling is a way I’ve combatted that problem without sacrificing my inner nature. Thus, I’m a smiler. At this point, it’s second nature to me. For today’s post, I tried to come up with some interesting information about smiling and to make it light-hearted so maybe you smile while reading it. Enjoy!


Fun fact: There are two types of smiles

I went searching for real scientific research into the personal benefits of smiling. In doing so, I learned that a French neurologist categorized smiles into two types.[1] The doctor’s name was Guillame Duchenne, so the two types are the Duchenne smile and the non-Duchenne smile. He apparently wasn’t that creative with coming up with names. Here’s the difference in the two:

  1. Duchenne smile is a smile that engages the muscles around both the mouth and the eyes.
  2. Non-Duchenne is a smile that only uses the muscles which raise the corners of the mouth. [2]

Benefits of smiling

This article by Erin Coleman nicely links to research and lists 7 benefits of smiling: https://benefitsbridge.unitedconcordia.com/top-7-health-benefits-smiling/

The one study she didn’t include, but I found and wanted to share was about Botox and frowning. The researchers studied people with Botox injections who were not able to frown. The study found those people were happier! How fabulous is that? Botox not only helps with the crows feet we’ll get from Duchenne smiles, but it will make us happier!

Lesson for today, smile more and get Botox!


Allergan, the company behind Botox, does not sponsor my blog, but if they’d like to start. I’ll accept payment in the form of free injections.
