What are some facts about human biology and why are they interesting?

 The human body is an amazing machine, with some oddities."

You can brush your teeth too aggressively. This can wear down the enamel and make your teeth sensitive to hot and cold foods.

Goosebumps evolved to make our ancestors' hair stand on end, making them more threatening to predators.

Wisdom teeth are useless. They are remnants from hundreds of thousands of years ago. As the brains of early humans grew, they reduced the space in the mouth, thus eliminating that third set of molars.

Scientists aren't sure exactly why we yawn, but it may help regulate body temperature.

Your nails don't grow after you die.

If they were placed end to end, all the blood vessels in the human body would circle the Earth four times.

Humans are the only animals with chins.

When you breathe, most of the air enters and exits through one nostril.

Every few hours, the workload shifts to the other nostril.

Blood makes up about 8% of total body weight.

The human nose can detect approximately 1,000 billion odors.

You have two kidneys, but you only need one to live.

Navels grow special hairs to catch lint.

The satisfying sound of your joints cracking comes from gas bubbles popping in your joints.

The skin is the largest organ in the body and can make up 15% of a person's total weight.

Thumbs have their own pulse.

Your tongue is made up of eight intertwined muscles, whose structure resembles that of an elephant's trunk or an octopus's tentacle.

Genetically, all humans are more than 99% identical.

The foot is one of the parts of the body most sensitive to tickling.

The extraocular muscles of the eye are the fastest muscles in the body. They allow both eyes to flip in the same direction in a single movement lasting 50 milliseconds.

A surgical procedure called selective tonsillohippocampectomy removes half of the brain's amygdala, and with it, the patient's sense of fear.

The pineal gland, which secretes the hormone melatonin, gets its name from its shape, which resembles a pine nut.

Hair grows rapidly—about 15 cm per year. The only thing in the body that grows faster is bone marrow.

No one really knows what fingerprints do, but they can help remove water from our hands, prevent blisters, or improve our sense of touch.

The heart beats more than 3 billion times in an average human lifetime.

The blush is caused by an adrenaline rush.

How long can a human being go without eating?

In 1965, a 27-year-old Irishman named Angus Barbieri, who suffered from severe obesity, did it for 382 days.

He survived for over a year on just his body fat, plus water, other fluids, and supplements, going to the bathroom approximately once every 40-50 days.

The sensational fast was prescribed by Dr. William Kinnear Stewart and took place under controlled conditions, with frequent blood tests and hospital monitoring.

Initially, the treatment was supposed to last only 40 days, but Angus unexpectedly found himself calm, stating that his body was getting used to the absence of food and, thanks to his great desire to achieve the goal, he decided to continue with the treatment. (bitter end.)

In the end, starting from an initial weight of 207 kg, he managed to lose 125 kg, thus reaching his ideal weight of 82 kg.

He broke his fast on the morning of July 11, 1966, by eating a boiled egg, a slice of bread with butter, and a cup of coffee, stating in a later interview that he enjoyed the meal very much, but that it immediately made him feel full.

In the following months and years, he continued to be monitored by doctors, and the last check-up, five years later, showed that his weight remained below 90 kg, a value he maintained for the rest of his life.

What will be challenges to establishment of human colony on Mars

 There are some problem to establishment of human colony on Mars:

1. Journey form earth to moon take approximately 1yr. for example India launch it's satellite for mars mission in 5 nov 2012 and reached mars Orbit in 24 sep 2013 this long time lead to some problem:

A). Long time spend in Zero Gravity leading to weakness of muscles including heart muscles also which was increase the risk of heart attack.

B). It also lead to the weakness of Eyes which was known as stress graft syndrome.

2. In the Mars extreme weather condition in a night time temperature around -153°C and day time around 20 degree Celsius where human do not sustain and technology for it is very costly.

3. Mars atmosphere is thin and It is primarily composed of carbon dioxide (95%), molecular nitrogen (2.85%), and argon (2%).Without a pressure suit, low atmospheric pressure would cause human blood to boil.

4.Lacking a magnetic field, the surface is bombarded with high-energy cosmic rays, requiring radiation shielding for any long-term habitation.

5. Mars Gravity it very less around 38% of earth and exists of iron oxide highly reactive dust—often described as nanophase iron oxides—which poses a significant health hazard if inhaled, ingested, or brought into human habitats.

6.No liquid water exists on the surface now, there are huge, permanent polar ice caps made of water and carbon dioxide, and potentially more water frozen in sub-surface ice

7.Future astronauts will face extreme isolation, confinement, and the "Earth-out-of-view" phenomenon, which will challenge the human psyche.

8. There are some also a morality issue vehicle do not carry all the people of the earth and what happened with the remaining person who has not going to the mars ,it's unfair

why We do not try to maintain earth in human condition rather thanmake it inhabitiual ?

What are the most mind-blowing facts about the human brain?

 1). The Brain Feels No Pain.

There are no pain receptors in the brain. That's why surgeons can perform brain surgery on a patient while they are still awake.

2). Men's Brains are 10% Bigger than female.

3). When you’re awake, your brain produces enough electricity to power a small light bulb.

4).Surgical removal of almost half our brain is possible with little or no effect on personality or memory.

5).They Saved Einstein's Brain.

After Albert Einstein’s death in 1955, scientists all over the world scrambled for the opportunity to get a piece of his brain. It was a pathologist by the name of Thomas Harvey who got to it first.

6) It is a widely perpetuated myth that most or all humans only use 10 percent (or some other small percentage) of their brains.

The 10 percent myth has inspired many references in the cultural imagination. Films like "Limitless" and "Lucy" are based on the same.

7)."Inception" is Real

It turns out, there is something called Lucid Dreaming, where a person could control the outcome of a dream while in a sleep-like state. It has its roots in ancient Tibetian Buddhism.

What are some mind-blowing amazing facts about the human body?

 This is where I was yesterday. Blue skies, warm breeze, fresh air. I walked 10 miles to have lunch at that spot. Its buried in my memory, I've been in other spots but this days sticks in my head.

So what has this to do with amazing facts of the human body?

No matter how I describe that point in time, no matter how you percieve those photos, you didn't see it through my eyes.

Not many folk have ventured into human vision here, and the eye is a biological masterpiece. How much of all that you know was as a result of what you saw.

Amazing facts you want, amazing facts ye shall have.

Did you know each eye contains over 2 million working parts, yet unlike many organs the eyes dont grow much, they're almost full size at birth (Probably a reason babies look so darn cute…big eyes.)

The human eye is proper high resolution, there's no comparable equivalent but exceeds any modern digital camera. I believe the eye is equivalent to around 576 megapixels in resolution. Suck on that Kodak.

The eye is also unmatched in focus speed. There's no satisfactory equivalent, the extremely tiny ciliary muscles in your eye change the shape of the lens to focus from distant objects to something inches away in milliseconds. Cone cells detect shade of colour, human eyes have high density cone cells meaning they can distinguish between 10 million different shades. I didn't know that many shades existed! But my eyes do…

In perfect darkness the human eye can detect the smallest particle of light known as a ‘Photon.’ We can actually see a candle flame from 12 miles. The eye however works in tandem with the brain, it can't see on its own, and it sees upside down in photons.

Another amazing fact is that 50% of the brains resources are dedicated to the process of vision, someone has to be, the eye can rotate at speeds of 500 degrees per second. Every minute to keep in tip top condition we blink between 15-20 times.

So I'm nominating the eye to have some amazing facts.

What are some mind-blowing amazing facts about the human body?

 Sometimes there are Things we can’t see but is visible to people with extraordinary pair of eyes. There is a girl “Concetta Antico” who can see 100 times more Colors than normal human being.

Antico is a Tetrachromat, giving her eyes the ability to see up to one hundred times more colors than a normal human being.

In 2012 it was found that Antico had a genotype for potential Tetrachromacy a genetic condition that gives her four types of cone cell classes in her eyes (normal color vision humans only have three cone cell classes). Her extra cone class provides additional sensitivity in the region between the normal middle- and long-wavelength sensitive cones. One advantage provided by this extra cone class appears to be an enhancement of color in shadow and in dim lighting. Antico discovered her condition after collectors and students had begun sending her articles about the condition, after viewing her work.

Here is her few paintings which she has drawn.
