Who would have thought that the human body is capable of such incredible feats? From nutty bedroom antics to evolutionary leftovers, from sniffing out the truth to seeing the light, from endorphins to echolocation, from unique body odor to withstanding gravity 46 times stronger than Earth's, from breath control to regrowing fingertips, from eye color change to glowing, from jaw-dropping strength to forever growing body parts - these are just some of the amazing things that we have found our bodies can do.
We often take our bodies for granted, but the truth is that they are capable of some truly remarkable things. This list will explore some of the lesser-known, yet amazing abilities of the human body. We may be surprised to find out just how powerful and resilient our bodies really are. So, let's take a closer look at these incredible superpowers and see what makes us so unique.
Grow old, grow big.
![GRACKED PARTS OF OUR BODY GROW FOREVER As we age, our noses and ears keep getting bigger because they're made of soft tissue and cartilage that continues to grow. That's why some older people have larger noses and ears.](https://s3.crackedcdn.com/phpimages/imageset/6/8/0/889680.jpg)
Jaw-dropping strength.
![GRACKED WE CAN CHEW NEARLY ANYTHING The masseter, which is the muscle in the jaw, is the strongest muscle in the human body. It's so strong that it can exert a force of up to 200 pounds (90.7 kilograms) on the molars.](https://s3.crackedcdn.com/phpimages/imageset/6/7/9/889679.jpg)
Glow up, literally.
![GRACKED WE GLOW FOR REAL!) People give off a faint light that changes with the time of day, and their faces shine brighter than the rest of their body because of the fluorescent parts of melanin.](https://s3.crackedcdn.com/phpimages/imageset/6/7/8/889678.jpg)
Eye-opening change.
![GRACKED WE CAN CHANGE EYE COLOR It can happen for kids with light eyes to have them get darker as they get older, but sometimes it can go the other way and kids with darker eyes can end up with lighter eyes.](https://s3.crackedcdn.com/phpimages/imageset/6/7/7/889677.jpg)
Not so superpowers.
![GRACKED WE CAN REGROW FINGERTIPS People can only grow back certain parts of their body, like the top layer of skin and the ends of their fingers. But they can't do what salamanders can - regrow whole limbs. Scientists are still trying to figure out how salamanders can do this.](https://s3.crackedcdn.com/phpimages/imageset/6/7/6/889676.jpg)
Breath control: not just for yogis.
![GRACKED WE REGULARLY PREVENT OUR VOCAL CORDS FROM BLOWING UP When we talk or sing, our lungs act like a pair of balloons. Unlike a balloon, though, we can control how quickly or slowly we let the air out. This helps us keep a steady air pressure, so our vocal cords don't get blasted apart by too much pressure.](https://s3.crackedcdn.com/phpimages/imageset/6/7/5/889675.jpg)
Impressive, indeed.
![GRACKED WE CAN WITHSTAND GRAVITY 46 TIMES STRONGER THAN EARTH'S John Stapp was an Air Force pilot who experienced an incredible 46.2 Gs of force in an experiment. This was so powerful that it made him weigh over 7,700 pounds in a flash.](https://s3.crackedcdn.com/phpimages/imageset/6/7/2/889672.jpg)
Smell ya later!
![GRACKED WE ALL HAVE A UNIQUE BODY ODOR Your body has a smell that's like your fingerprints - it's unique to you and it's determined by your genes. Even if you change what you eat, your body odor will stay the same.](https://s3.crackedcdn.com/phpimages/imageset/6/7/0/889670.jpg)
Tongue-clicking: it's the new superpower.
![GRACKED WE CAN ECHOLOCATE LIKE BATS An American expert has taught blind children around the world how to echolocate by making a clicking noise with their tongue against the roof of their mouth. This sound can help them to sense things from far away, even when there is a lot of noise.](https://s3.crackedcdn.com/phpimages/imageset/6/7/3/889673.jpg)
Endorphins: nature's happy pills.
![GRACKED WE MAKE NATURAL PAINKILLERS Our bodies make endorphins, which act like natural painkillers and make us feel relaxed and happy. We can increase the amount of endorphins by exercising, getting acupuncture, meditating, having sex, playing music, laughing, and getting some sun.](https://s3.crackedcdn.com/phpimages/imageset/6/6/7/889667.jpg)
Talk about seeing the light.
![GRACKED OUR EYES ARE SUPER-SENSITIVE Our eyes are so sensitive that we can sense even a single particle of light in complete darkness. A research paper published in Nature Communications proved this, showing that people could detect a single photon 51.6% of the time.](https://s3.crackedcdn.com/phpimages/imageset/6/6/8/889668.jpg)
Sniffing out the truth.
![GRACKED OUR NOSES ARE HYPER-POWERED We can actually smell more than 1 trillion different scents - that's way more than the 10,000 we thought before. That means we can tell the difference between smells that are only very slightly different from each other.](https://s3.crackedcdn.com/phpimages/imageset/6/6/9/889669.jpg)
Evolutionary leftovers.
![GRACKED SOME OF US HAVE A MISSING TENDON MUSCLE 12 About 10-15% of people don't have a strong tendon in their wrist that's linked to a muscle that used to help our animal ancestors move around. It doesn't give humans any extra arm or grip strength.](https://s3.crackedcdn.com/phpimages/imageset/6/7/4/889674.jpg)
Nutty bedroom antics.
![GRACKED WE CAN PASS ALLERGENS THROUGH SEX In 2007, a 20-year-old had an allergic reaction after sex with her boyfriend. It turns out he had recently eaten Brazil nuts and his semen was causing the reaction. This is believed to be the first time an allergic reaction has been passed on through sex.](https://s3.crackedcdn.com/phpimages/imageset/6/7/1/889671.jpg)
