Butt. Rear. Tuchus. Derrière. Can. Caboose. Whatever you call it, the posterior is one of the most important parts of the human body. It plays many crucial roles in our daily lives, from allowing us to move around freely to helping us rid our digestive system of waste products. Despite all of its uses, most people don't know the most interesting facts about butts.
To a certain extent, mystery shrouds the butt. It's involved in some admittedly icky bodily functions, a fact that likely prevents a lot of people from fully understanding its usefulness. Simply put, we would be lost without our backsides. They are our constant companions, our allies, and our cushions - not to mention an endless source of humor, pleasure, and pain. And, as this list of facts about butts demonstrates, the rear can be just as fascinating as the human brain.
There's a beneficial reason hair grows on the butt. First of all, it prevents chafing of the butt cheeks when you walk or run. It also has an evolutionary function: butt hair holds in your natural scent, which is primal, and something that attracts others.
As long as it's serving a purpose and helps the body, maybe we shouldn't be so quick to wish our butt hair away.
Research suggests that a bigger butt could help you live longer. Fat in the lower body is generally more stable and does not break down as quickly as fat in the stomach and other areas. When fat breaks down quickly, it can release potentially harmful chemicals.
The butt also plays a role in trapping unhealthy fatty acids. It keeps them away from the abdominal area, where they can cause a variety of problems with the heart, kidneys, liver, and other internal organs.
Humans have very large butt cheeks compared to great apes, our closest animal relatives. Most of the human bottom is comprised of a muscle called the gluteus maximus. Without it, we wouldn't be able to walk, or at least not nearly as easily or efficiently as we currently do. This large muscle provides the strength and support humans require to walk upright on two legs.
Gorillas generally have flat bottoms, as they don't need the muscle to walk on their hands and feet. Over time, the human pelvis evolved to be wider, which elongated our hips and gave our butts their curviness.
When a person walks, there is a very brief moment when, with each step, they only have one foot on the ground. This motion requires balance, which is where the butt comes in. With the butt positioned significantly higher than the feet, the gluteal muscles have more leverage to keep them stable.
There is no hard and fast rule when it comes to how many times a day a person should do a "number two." The frequency of pooping can vary significantly between different people. Doctors instead outline a normal range most healthy people fall into.
An individual may have to poop once every three days or have to go up to three times a day. (Diet is an attributing factor to have often one goes.)
