10 Extraordinary facts about the Human Body that you probably didn't know!
I'd feel like a degenerate if I never imparted on you any knowledge valuable enough to at least make you look cool in front of your friends. The human body is a marvelous, complex structure with a plethora of mysteries and wonders from sneezes and yawns to Chronic headaches . Here are 12 interesting facts we do know. I have heard of some of these but not others, either way I think they are all truly amazing.
1. Every hour one billion cells in the body must be replaced.
If you drink I am sure the number may be more in the vicinity of the trillions....
2. A human eye can distinguish as many as 500 shades of the gray.
Although as a man, I can only think of about 2. Light gray and dark gray. Turn out it's more subtle than that i.e I'm an idiot.
3. Human thighbones are stronger than concrete.
That is quite amazing! I am surprised they ever break.
4. The human heart creates enough pressure to squirt blood 30 feet (9 m).
That would certainly be a pretty effective, undetectable one time use weapon....not recommended!
5. Our eyes are always the same size from birth, but our nose and ears never stop growing.
That is pretty interesting! In the case of people like Babara Streisand, their nose may in fact never stop growing.
6. The average cough comes out of your mouth at 60 miles (96.5 km) per hour.
If you face backwards and cough your way through a 100m dash, shouldn't you win easily?
7. A sneeze can exceed the speed of 100 mph.
If you sneeze on road with a 60mph speed limit should you get a ticket?
8. Human blood travels 60,000 miles (96,540 km) per day on its journey through the body.
Bare in mind the Earth's Circumference at the Equator: 24901.55 miles (40075.16 km).
9. 85% of the population can curl their tongue into a tube.
The practical application being that you no longer require a straw to sip your drink
10. Womens' hearts beat faster than men.
This is no surprise. An existence of nagging and complaining would require a greater blood flow...lol.
