Weirdest Facts About The Human Body
So you think you know yourslf pretty
good, do you? Well think again, the human body has been fascinating
scientists and researchers for ages now, some have even died for science
in order for us to know all that we know now, and yet… we still do not
know enough. I bet you had no idea that the acid in your stomach is
powerful enough to dissolve a razorblade. Are you a tennis fan? I know I
am and imagine my surprise when I heard that the surface area of just
one lung is equal to that of a tennis court. We have plenty more of
interesting and pretty amazing facts about the human body, so have a
look and prepare yourself to be amazed.
1. Facts about the Human Brain
- The speed of nerve impulses is 170 miles per hour. Surely you might
have wondered why that splinter that just made its way in to your toe
hurts so fast, well, it’s because of the super speed of the impulses
that travel from and to the brain. Pretty neat, huh? Now go and take
that splinter out before it starts hurting even more
- You brain cells can store five times as much information as there is in the Britannica Encyclopedia. So far, the scientists haven’t yet reached a definite value as to how much information our little brain can “absorb”, but it is estimated around 170 terabytes so you better put all of that space to good use.
- Your brain can not feel pain! Yep, that’s right, the brain itself, as an organ can not feel pain despite the fact that it is the center of pain. So if you’re wondering why your head hurts from time to time, take an Advil and keep reading this article. The brain is surrounded bu plenty of blood vessels and nerves which are responsive to pain, hence the head aches.
2. Internal Organs
- You have over 60 thousand miles of blood vessels inside of you. Now if you don’t know how much that is, know that the Earth’s circumference is about 25 thousand miles, so if we were to stretch out all of the vessels in our body, we could go around the Earth two and a half times.
- The human liver has over 500 different functions. Practically, the liver handles quite a lot, it doesn’t just sit around and starts hurting after a night when you’ve had too much to drink. It makes proteins, it kills old red blood cells and these are just a few of it’s functions.
- Do you like roses? Well then you should know that the aorta’s diameter is close to that of a garden rose.
- Sneezes come out with the speed of 100 miles per hour making it impossible for you to sneeze with your eyes open, but that shouldn’t stop you from covering your mouth when you sneeze… Coughs come out with “just” 60 mph, it’s no wonder why you catch a cold so fast when it’s flu season and you’re at the office.
- Your feet have 500,000 sweat glands which can produce about one pint of sweat per day, it’s a good thing they don’t though…

Blondes have an average of 146,000 follicles, while eople with lack hair have 110,000 and those with brown hair have just 100,000. It could be worse… red headed people only have 86,000 follicles.
- Human hair is practically indestructible. I mean sure, if you even put hair near a flame it goes up in smoke, but in theory, its decay rate is so slow that hair is virtually non-disintegrative.
- Just one individual human hair can hold 3.5 ounces, the approximate weight of two candy bars. When it comes to candy bars, I’d rather eat them rather than hang them in my hair.
