I’m a huge fan of TedTalks. Recently, I stumbled across one on the science of smiles by Ron Gutman, a professor from Stanford University whose mission is to help everyone live happier, healthier lives.

Gutman talks about a 30-year old study from the University of Berkeley, California that looked at old photos in school yearbooks and measured the success and well-being of the graduates throughout their lifetime based on their smiles. The students with the biggest smiles tended to lead more successful, well-rounded lives.

Another study involved looking at old baseball cards and the longevity of the ball players in correlation to the smiles on their cards. The ball players with the biggest smiles lived the longest.

Gutman says one-third of people smile more than 20 times a day, but sadly 14% of us smile less than 5 times per day. Children smile more than 400 times per day.

He claims smiling creates the same positive brain stimulation as eating up to 2,000 bars of chocolate!

Smiling is one of the most basic expressions of humans and something we all do every day.

This week’s #HappyAct is to make a conscious effort to smile at least 20 times a day this week and if you see someone sad, struggling or frowning, ask what’s wrong, tell them a joke, or do something to put a smile on their face.
