You may think you know your body, but we suggest you do a recheck. That's because the human body is among the most fascinating creations of nature and evolution. Yes, there are theories about alien technology and slavery as well, but that is a topic for another day. To satisfy your curiosity, here's a look at some of the most amazing facts about the human body.
One liter of saliva per day - Your mouth produces an average of 1 liter of saliva every day. And most of it is swallowed, unless you have a terrible habit of spitting. Saliva performs a wide range of functions including digestion, teeth remineralization, antibacterial action, etc.
60,000 miles blood vessels - Your body has an endless system of veins, arteries and capillaries. If you were to put all of it in a single line, your blood vessels will cover the earth twice. Sounds bizarre, but it is true.
Light emitting body - Human body is not exactly a light emitting diode, but it does give out infrared radiation or infrared light. But you won't be able to use yourself or your partner as a torch, as the amount of light emitted by human body is much less than what our eyes can see.
Thoughts faster than light - Fastest thing we know is light, which travels at 186,000 miles per second. Your thoughts are estimated to be even faster, as it takes virtually no time.
3 billion heartbeats - The heart of an average person who lives to around 70-80 years will beat approximately 3 billion times. Bonus fact, heart is the only muscle in body that does not tire. Heart muscles comprise special cells called cardiomyocytes that are virtually fatigue resistant.
Shark teeth - Nature seems to be using the same standard when it comes to teeth. It explains why human teeth has the same strength as shark teeth. Our teeth are the hardest part in our body. It is capable of withstanding more than 5000 pounds of pressure per square inch.
1 trillion scents - Research findings indicate that a human nose can detect around 1 trillion different types of scents and odors. So, why do we need dogs to find the evil guy? That's because dogs are even better at detecting smells, equipped with four times the number of smell-sensitive receptors in their nose.
Heavy blood - If you are overweight or obese, you can blame it on your blood. The amount of blood is around 7-10% of the total body weight of an individual.
A billion eye blinks - Your eyes blink around 15-20 times every minute. They help keep your eyes moist and clear dust and debris. Over a lifetime, you would have blinked for roughly a billion times.
New skin every month - You may have seen snakes shed their skin. But not many know that humans too get a new skin every month. Only difference is we do not have to slither around to get the dead skin off our back. In your lifetime, you would have got more than 1,000 new skins.
