Hugo Critchley further explained, “Our bodies synchronise and when we like the other person, we even copy his behavior. Next time you chat with a friend, take note of how you’re sitting—it’s pretty likely that you will be the same. Scientists believe it’s our way of telling each other that we’re partners. Through body language, humans give each other very subtle(΢ÃîµÄ) but clear signals that show emotions.”

So, what lessons can we learn from this? “Spend time with happy people—otherwise your health could suffer,” said Critchley. “When we’re sad, our body goes into fight or flight mode. But when we’re happy, our body works normally and we feel relaxed and positive. So we look bright, our skin glows, we feel healthy and it affects everyone around us.”
