Laughter is only two things. Breath plus sound. That's just like speaking. Only without words and thinking.
We don't even need anything funny to laugh. All over the world, babies laugh before they understand humor or know how to speak a language.
Culture, parents, and teachers give us the idea to take life seriously. But the laughter you were born with has a different message for you.
Learning to laugh on purpose is fun, feels good, supports your health in many ways, and will lead you to discover many other gifts you also have inside you, all the time, even when you don't realize it.
