CRACKED.COM ESCAPING GUT BLOOD GIVES YOU BUTTERFLIES IN YOUR STOMACH. Sometimes your reptile brain senses an anxious situation, but can't differentiate between a Tinder date and a hungry jaguar.

It also relaxes the sphincter, causing loose bowels. So the next time you crap yourself during an intense Pixar scene, know that it's just science! — Source: Scientific Reasons for B.S Things Our Bodies Do

So savor that cool ranch Dorito like it's fine wine, then spit it in a bucket like a true connoisseur. — Source: Scientific Reasons for B.S Things Our Bodies Do

Healthy Foods

GRACKED.COM IT'S TOUGH FOR OVERWEIGHT PEOPLE TO STICK TO DIETS BECAUSE OF THEIR TASTE BUDS. Weight gain leads to an impaired sense of taste, and a recent study may have found out why: inflammation of the taste buds.

Which proves that we still haven't figured out how to make healthy food taste good. — Source: Scientific Reasons for B.S Things Our Bodies Do

25

CRACKED.COM YOU GET CARSICK BECAUSE YOUR BODY AND BRAIN ARE ARGUING. During a car ride, your eyes recognize movement while your brain thinks you're just sitting. Your thalamus comes to the conclusion that you're being poisoned, and hits the gag button to clear it from your system. If you're driving, your brain is getting more information, which is why drivers don't get sick. — Source: Scientific Reasons for B.S Things Our Bodies Do

THAT ACHY FEELING WHEN YOU'RE SICK IS CAUSED BY YOU, NOT THE VIRUS. White blood cells are part of the body's defense system, but also cause sore throats.

The process causes achiness, which may be a way of alerting you to injuries where the infection began. That's right, your aches and pains are your body's own fault.

23

PEOPLE COUGH AT CONCERTS BECAUSE WE'RE SOCIAL CREATURES. The average human coughs 16 times a day, but is twice as likely to do so during a concert. Why?

ONE NOSTRIL ALWAYS GETS STUFFED UP TO KEEP THINGS MOIST. In addition to smelling, the nose warms and humidifies air to make it friendly for the lungs.

One is always more stuffed than the other to keep each side adequately moistened. So you can finally stop licking the inside of your CRACKED.COM nose and grossing everyone out. — Source: Scientific Reasons for B.S Things Our Bodies Do

PAPER CUTS HURT SO MUCH BECAUSE THEY'RE THE PERFECT STORM OF PAIN. Paper cuts inflict more pain than most injuries because fingertips are full of nerve endings. And even the most smooth-edged paper is as jagged as a sling blade at the microscopic level. Instead of delivering a clean cut, it tears open a sloppy wound that doesn't bleed or clot, leaving it exposed. This summer, Jigsaw's getting a sequel, and in it, he has a ream of printer paper.

COFFEE WREAKING HAVOC ON YOUR SYSTEM? BLAME YOUR HORMONES.

FILTH, NOT CHLORINE, TURNS EYES RED IN A POOL. Chlorine has been unjustly blamed for the way your eyes redden after an afternoon flapping around in a swimming pool.

ASPARAGUS MAKES YOUR PEE SMELL NASTY BECAUSE OF SULFUR.

COLD WEATHER MAKES YOU PEE FOR SURVIVAL. Cold diuresis is when your nervous system tries to stave off hypothermia by causing capillaries in the limbs to constrict and reroute blood to the more essential organs.

DRIVING MAKING YOU SLEEPY? BLAME THE VIBRATION. Your car is literally hypnotizing you. About 20% of fatal crashes are caused by fatigue, which can creep up after just 15 minutes of driving.

Humans are the only primates withoute a penis bone. DSQUARED2 DSQUARED2 The penis bone (also known as baculum) increases a male's chance of having offspring by making sexual intercourse last longer.

Compared to other apes, humans are born incredibly early. While other apes are born around 70% mature, humans are born just 20% mature. In fact, our long childhoods are unique to us.
