Our bodies are fearfully an wonderfully made. If you ever doubt that, just take a basic microbiology class. You will come away wondering how on Earth we even stay alive for more than 10 seconds on this planet. Yet, we don’t just survive on this planet, we thrive. Our bodies are works of art, of great engineering accomplishments, and downright awesomeness.
Someone warn the Manhattan Project, because I’m about to anatomically blow your minds:
Humans actually glow!
No, I’m not talking about weirdo mysticism and “auras”. A study in Japan found humans actually bioluminesce and glow in the dark. “Oh maybe they were just using thermographic cameras to”… FALSE. This was not heat they were picking up. The researchers used a charge-coupled device camera than picks up photons (particles of light) and found up to 3000 photons/s·cm2 being emitted. Though the light that we emit, thought to come from free radicals in metabolism, is 1,000 times weaker than our human eyes are able to pick up, we can still literally be the light of the world.
We can taste sounds!
A condition called synesthesia can cause senses to overlap. In other words, some people can taste words, hear colors, and every other possible combination. It is more common than you may think, with 1 in 23 people having some form of it (2) . It is hypothesized when humans’ sensory system is developed, the segregation of the neurons into different compartments for each sensory organ does not happen. The “cross-wiring” is kept and the neurons continue to span multiple sensory organs (3). Here is a great video to show you what its like to have synethesia:
BONES OF STEEL
Human bone beats any structural material we use in our cities. Human bone’s compressive strength can reach to 47,000 lbs/in2 (4). Concrete at your local store will be around 5,000lbs/in2 while Ultra high performance concrete still falls short at a max of 36,000 lbs/in2 (5). Bone is also 5 times stronger, 10 times more elastic, but but weigh much less than steel (6).
Think of it this way, a matchbox size piece of bone can support 9 tonnes, while a concrete piece will only support 2.25 tonnes (7).
We Are Sensitive.
Swedish scientists proved our tactile perception is far more sensitive than we thought. Their subjects were able to determine nano-wrinkles on an otherwise “smooth” surface. That may not sound all too impressive, until the researcher put it in a way we can all understand: if our finger was the size of the Earth, we could feel the difference between houses from cars just by running a fingers over them (8).
And here your step-mother thinks you aren’t doing anything with your life. Silly step-mom. You don’t know my life. I CAN SEE SOUNDS. Whatchoo know about my bones of steel?!
