Laughter

Everyone can understand laughter, no matter where they are in the globe. Nevertheless, very few people are aware of why we laugh, why we laugh, or even what occurs to our brains when we laugh. One of the most perplexing aspects of human behavior from a scientific perspective is laughter, and we're still no closer to unraveling it.

We don't always laugh in response to anything cheerful or positive, despite what the general public believes. It can occur as a result of tickling, medications, mental illnesses, or a wide range of other circumstances that have nothing to do with happiness. Studies have shown that most laughter is uncontrollable and in response to social cues that aren't at all humorous on their own. Laughter also rarely occurs in response to something amusing. However, many ape species laugh as well, suggesting that laughter is not just a uniquely human response adapted to our particular social milieu.

Then there's the issue of exactly which body parts are involved in laughing. If you assumed that laughing only affected the brain, think again. For many people, laughing also affects the legs, hands, and torso, as well as other seemingly unconnected portions of the body.
