10 Body Parts You Can Live Without

Over time, humans have evolved into stronger, healthier and less dependent beings. Because of man's many changes, we no longer depend on certain body parts to keep us alive and can do just fine without them. Even some of the most vital organs, such as the kidneys or lungs will sustain life with just one of each. Although no one likes having surgery or complications from a "useless" body part, it's nice to know that you can live without these body parts:

  1. Tonsils
    Tonsils are the tissues located in the back of your throat, where germs coming in through your mouth and nose are trapped to protect you from infection. Sometimes tonsils become infected, enlarged or inflamed, which is called tonsillitis. If the swollen tonsils interfere with your breathing or swallowing and you have repeated infections that aren't treatable with antibiotics, they may need to be surgically removed. Tonsillectomies are pretty common and you'll certainly live without your tonsils that keep getting you sick.
  2. Adenoids
    Similar to the tonsils, adenoids are masses of lymphoid tissue that are located higher up, behind your nose, and trap bacteria and viruses that you breathe in, protecting you from infection. Adenoids generally lose their purpose after age 3 and begin to shrink around 5 years old. When adenoids become infected or swollen, they can affect your breathing and cause pain. If the swelling persists or you have reoccurring infections, you may need to have an adenoidectomy to surgically remove the adenoids. This is often done during a tonsillectomy, as well. Because they serve little purpose after your third birthday, you'll be just fine without them.
  3. Wisdom Teeth
    Very few people get to keep their wisdom teeth, but don't worry; you're wiser to have them removed if it's recommended by your dentist. These large molars usually appear during the ages of 17 and 25, mostly in sets of four or less. Wisdom teeth tend to come in sideways and affect other teeth in the process. These massive chompers are prone to infection and cavities because they are so hard to clean, and they aren't needed by humans anymore. So, it's a wise move to have your wisdom teeth removed.
  4. Male Nipples
    Males nipples have long been a mystery to humans. We know that in early embryonic stages, unborn babies are essentially sexless; therefore both women and men have nipples. However, male nipples are vestigial, meaning they are not functional. Male breast tissue can actually form cancerous tumors that can be just as fatal as female breast cancer. Bottom line – male nipples are essentially useless and something you could live without.
  5. Appendix
    The appendix is a muscular tube attached to the large intestine, and its purpose is to digest cellulose from a large herbivorous diet. Experts have found the appendix to be a vestigial organ that has little use today and you can certainly live without. It may even cause more harm than good, specifically when the appendix becomes infected and ruptures.
  6. Body Hair
    Body hair has minimal purpose today, as humans have evolved we no longer need our fur to keep us warm. One factor to this argument is the erector pili, smooth muscle fibers that cause goose bumps. When humans are cold, the erector pili become activated and give you goose bumps, but your hair just stands on its end and doesn't actually warm you up. Therefore, other than eyelashes that trap particles and eyebrows that keep sweat out of your eyes, most body hair is useless.
  7. Gall Bladder
    The gall bladder is a small organ of the digestive system that stores bile and aids in digestion. This organ can also become problematic when gall stones are produced from cholesterol or too much bilirubin in the bile. These painful stones can be as small as a grain of sand or as large as a golf ball and cause a great deal of pain and sickness. When this occurs, the gall bladder will generally be removed and you'll be happier without it.
  8. Sinuses
    Sinuses are another mysterious body part of the human body. What we do know about them is that they are abundant air-filled spaces in the nasal cavity that can become easily infected. They are especially irritating to allergy sufferers, and something we could certainly live without.
  9. One Kidney
    The kidneys are a pair of vital organs that are located near the middle of the back, below the rib cage and one on each side of the spine. These bean-shaped organs have several functions like keeping the blood clean and chemically balanced, as well as activating vitamin D and regulating blood pressure. Kidney disease may cause kidneys to fail, usually resulting in the need for a kidney transplant. However, a single kidney with only 75 percent of its functional abilities can keep you alive and sustain itself pretty well. The same can be said for a healthy kidney donor.
  10. Tailbone
    The tailbone, also called the coccyx, is the last part of the vertebrae and the only vestiges left of the tail. Other mammals use their tails for balance and communication, while our tailbone no longer has a major purpose but to hurt really bad when you land on it. In fact, there have been several medical procedures where the tailbone has been surgically removed with little or no adverse effects, therefore highlighting its uselessness.
