When You're Smiling, The Whole World Smiles With You
There’s something magnetic and endearing about a smiley face. When you see someone smiling or laughing, you can’t help but smile back. And, so too, are others drawn to us when we flash a smile.
Neuroscientist Dr Keith Kendrick wondered if animals feel the same way. His team did a study to see if sheep would gravitate to a person with a smile over someone who was showing anger on their face. It turns out that, if given a choice, these fluffy beings were also more drawn to a happy face than a stressed out one.
I feel like this sheep is smiling back at us.
