What does a hug give to a person?

It is said that each of us needs 4 hugs a day to survive, 8 to feel loved, and 12 to become a real person... Of course, the numbers can be disputed, but what matters here is the principle, not the numbers. So, what does a hug provide? 1. Courage. It's very interesting to observe how contests happen behind the scenes. Today, it's common to place cameras everywhere, including backstage. Each contestant is hugged by their mentor, parents, or friends before going on stage. Through a hug, they convey confidence: "Everything will be fine, you can do it, you're ready, I'm with you, you're not alone."
