Your smile might be a measurable predictor of your lifespan
In short: A simple facial expression does more than signal happiness; it may influence your physical health and longevity. This video explores the evolutionary biology and measurable well-being effects of smiling.
Ron Gutman examines various studies to reveal how smiling functions as an evolutionarily contagious behavior. Beyond its social utility, research suggests that a smile has a measurable impact on overall well-being and can even serve as a predictor of how long an individual will live.
The presentation contextualizes these biological effects by looking at the history of the expression, noting how depictions shifted from the tight-lipped faces of medieval portraits to the wide grins seen in early photography.
